Ultrasonic Cleaning: How To Get A Super Clean Bike Chain & Cassette

[@gcntech]

Would you use an ultrasonic cleaner on your bike parts?

[@ianphil397]

I need one for my .22LR moderator. Might as well use it for my bike chain as well.

[@johnbay1234]

About once a year after winter wash off the road salt.

[@davidburgess741]

Already use one. Have moved away from using kerosene. Curious if there is a safe solvent for wax based chain lube. Some recommend boiling water. This does not seem safe or practical. Have dipped chains into molten wax, but not so sure it gets clean enough. Would it work to have molten wax in ultrasonic parts cleaner?

[@milybanily]

I do.

[@jeffbrunton3291]

Yes, especially if it pays for itself by getting a couple extra months out of my drivetrain

[@bikedawg]

Pro tip for Ollie--- put your chain and cassette in a zip loc bag and fill it with the cleaning solution. Then place that bag in the ultrasound machine after filling the machine with water. That way, you do not have to use as much solution AND you do not have to clean the machine afterwards. The ultrasound goes right thru the bag and will not affect the cleaning.

[@bushsons100]

What litre size do you reckon that cleaner was?

[@rudyramirez4623]

@@bushsons100 That one is probably a 3 liter model.

[@Methodical2]

I suggest you use a glass jar because it allows the ultrasonic frequency to penetrate with enough strength to thoroughly clean your item vs plastic.

[@Alex-kr7zr]

Or a pickle jar. Not for the cassette, but for the chain

[@peterdelmonte9832]

Does anyone know the size in litres of an ultrasonic cleaner large enough to take a chainwheel with a fixed crank, please. I’m only going to buy one!

[@prestachuck2867]

Here’s a little constructive suggestion for you, Ollie. When showing the “after cleaning” results, stop wiggling and waving the parts around so much. It’s difficult to tell how clean the cassette actually is since the eyes cannot focus on it long enough. Also, let us see the other side of the cassette where most of the chain sludge accumulates. Otherwise, great video.

[@felderosa]

yeah, id really like to see a still frame closeup of the chain before/after, plus a still shot of the cassette

[@mmmikeyyy]

yes! I found this video so frustrating to watch! He looked at his cassette, marvelling at the difference between the cleaned half and the untouched half, but we couldn't see anything. We did not even get a real good look at the clean chain. I just got an ultrasonic cleaner and did some tests yesterday cleaning a bicycle chain. Tried dishwashing soap. Not good. Tried dishwasher soap. Not good. Tried Oxyclean. Not good. These attempts removed fine particles of dirt and apparently metal that I could find at the bottom of the tank, but left sticky muck in place. Finally tried a mixture of white vinegar and dishwashing liquid soap. That worked. But the chain turned black. All tests at about 140F if someone's curious. I quickly rinsed the chain after the last test and left it to dry. The vinegar solution might be a terrible idea as it may have stripped a protective coating preventing rust (a very thin layer of rust quickly appeared when the chain was dry). Anyway, as is often the case, the comment section is just as informative as the video, if not more. Love the idea of another poster, consisting of sealing the part to be cleaned in a ziplock with the cleaning solution (will try diluted Muc-Off degreaser next), before immersing the bag in water to avoid unnecessarily diluting the cleaning solution. Update: just checked on my cleaned chain and I must say that it looks fantastic finally (cleaned it about 12 hours ago). If someone's curious: I cleaned it with a solution of about 40% double strength white vinegar and 60% water plus a couple of tablespoons of dishwashing liquid soap. Half an hour at 140F. Then rinsed thoroughly, wiped it and left it to dry. Chain was a dark black coming out of the solution, but all the muck was gone (at last). A very thin layer of rust appeared at the surface of the dry chain. I coated it with Muc-Off dry lube (liquid when applied...). Wiped off excess lube. Now the chain is no longer black: the original dark gray is back. There's absolutely no rust visible. Could vinegar and soap be a good idea after all?? (note that it's extremely cheap...)

[@abcd969696]

[@philippbeckonert1678]

[@SaleenS351R]

Unless you’re all accusing GCN for swapping out the parts for clean ones to act like it worked, he clearly shows the chain and cassette after it was in the bath. Noticeable difference and you can see the half clean, half dirty cassette, no problem.

[@erobertson1417]

“The chains much cleaner, check this out” The shot of the chain shrinks to less than a quarter of the screen. Nice.

[@brianschiff35]

I’ve been doing this for years. I but the chain in a zip lock bag with degreeer and but hot water in the ultrasound cleaner. This way I use less chemicals and I don’t dirty the tub of my ultrasound cleaner.

[@berthull9333]

I have been doing a similar hack. I have a large 10 liter cleaner (2.5 gallon) which is too big for one chain at a time but great if you want to do a crank or a whole groupo (or auto parts) so I have a few plastic tupperware bowls I use for small parts and fill the rest of the space with water. I like your zip-lock idea better. I'll give that a try. I think your way would use even less solvent. saves money and less waste.

[@durianriders]

Good tip!

[@Mr.FastZombie]

How much degreaser do you put in the bag?

[@daysetx]

[@Booyamakashi]

[@zyghom]

I am wondering why, the most important scene - showing the chain after - was so small and so short... just asking ;-)

[@foxtrot978]

I find the difference is not that spectacular on first sight. But whatever dirt is still on the chain comes off much easier. Also the roller internals will be completely dry. Which is also what makes the re-lube with oil or wax bath so important

[@tehpanda64]

Yeah im guessing he diluted his degreaser too far and it didn't work as well as expected. Really wanted a before and after of him feeling for grit by flexing the chain :/

I've been trying to shop for this but, nobody ever mentioned what volume do we need, 3l,5,6, 10 or more Liter in order to be able to completely submerge a 40T cassete inside together with front 54t front cogs chains and other drivetrain parts? what frequency & wattage should the device be capable of for for most efficiency? what detergent should one use? they sell some detergent with the device but, can one use just water and dish detergent and a bit of aceton, thinner isopropyl alcohol or some other sort of industrial degreaser. These are question I wish they answered with this video.

[@SignorLuigi]

I would love to have seen a more thorough and up-close look of how the chain and cassette looked after they were cleaned. Does it beat petrol in cleaning ability? I know. I know. Petrol is the devil. I soak my chains in a sealed container so no vapors escape. I use a coffee filter and recycle the petrol I use to clean my chains and can get many, many cleanings from just a little of the solvent. I also clean outside. I also use gloves. I also bike everywhere and so use much less petrol per day than the average human. Plus...

[@TryboBike]

For anyone willing to use ultrasonic cleaners: 1. _DONT_ use dedicated ultrasonic liquids. They often are caustic and it will destroy anodizing. 2. Get an unit with a release valve at the bottom, so you don't need to tip the cleaner to get rid of the dirty water. It gets messy otherwise. 3. Likewise - get an unit with heating, make the process faster 4. To throughly clean someting - two - three baths are needed. 5. If you clean something with exposed steel in water based bath - dry it throughly ( a heat gun is helpful ) otherwise rust will get into the part real fast ( as in: within hours ) 6. I found isopropyl alcohol bath to be great to dissolve any old grease from shifters. Then a quick spray of the innards with light oil and its good as new. 7. "Real" men use gasoline bath to clean old grease. Gasoline in ultrasonic bath is cancerous, toxic, flammable and explosive. But cleans stuff real good. EDIT: 8. If any makers read this - make a powerful ( 500+W ) heated bath with shallow tank, but square size - something like 30x30cm on the surface and 3-5cm in depth. It would be great for cleaning chainrings, cassettes and whatnot.

Stick your chain in a jar of degreaser and put it on top of your front-loading washer. Wash load and let the vibration agitate out the dirt ;)

[@YelCan]

That's good, but don't even need a washing-machine agitator. I put mine in old paint cans (clean and remove the lip with a can opener). Agitate for a few seconds every time you walk by. Done. Pour the dirty solvent (in the US, use "low odor paint thinner") in a gallon container and let settle. Once settled, pour the liquid (it'll be stained but have no particulate) into your "clean" one-gallon solvent container, and re-use. One gallon of solvent will last ten or more years. At some point the solids won't properly settle. Properly discard the container with the settled solids (might have ½" of crud) and start a new one.

[@gbalock]

[@magicknight8412]

Needed to see the chain close up also for longer! Also the cassette was hard to see the difference. Might have to get one of these !

[@MattWarfield]

As Chris Williams mentioned, add water only to the USC. Place the cleaning solution and the part into a glass/plastic/metal container and set the container into the USC. This not only allows easy cleanup and storing of the cleaning solution, but also will let you clean parts taller than your USC if your container is tall enough.

[@shanehansen4355]

I just purchased a UltraSonic cleaner and found that starting with hot water from the tap with some Simply Green cleaner works best. I have never had a chain and cassette as clean as this. From there I used an old pot and used Paraffin Wax on the chain. I based upon my research and the help of GCN I believe that this will reduce maintenance cost in the future and reduce the amount of chemicals that will be needed to keep my bike in top shape. Highly recommend.

[@TheRealMichaelB]

Make sure you use the "Extreme Simple Green Aircraft & Precision Cleaner" the standard stuff isn't recommended any more (at least for chains) - Even though I used the standard Simple Green for years when I worked as a bike mechanic in the early 90's and, as far as I know, there were not catastrophic failures as a result :)

[@Drzhounder]

By god I think Ollie is in his element, SCIENCE! Good job. The points I would want to make to the viewers are to be sure to get a unit that is large enough to submerge all the parts you want to clean. I got a small one that is good for small parts and chains but not cassettes, similar to Ollie's issue. Another point to consider is what to do post cleaning. After you rinse off the components, be sure to dry them as thoroughly as possible. You now have water and degreaser in the tightest of spots. A compressor or air canister to blow them out works very well. Then be sure to re-lubricate them almost immediately so that you don't introduce rust to the components. I ride a lot and I will clean my drive train after each ride. I use sonic cleaning about once per chain in the middle of its life, so for me about every 600-800 miles or 1000km-1300km depending on road conditions.

Here is a tip to avoid having to cleaning out the greasy the black bits coating your ultrasonic cleaner tank tank. Put the cleaner solution and the parts in a zip-lock bag. Put some water in the tank and drop the bag in. The bag won't effect the cleaning effects of the ultrasound. Less muss and fuss.

[@arthurstreet2811]

ozcycle did a review of ultrasonic vs handheld chain cleaner vs homemade cleaner. ultrasonic came out cleanest with 2 runs of 15 minutes each.

[@Ender06]

A ultrasonic cleaner hack: Fill the cleaner with normal water, then take a old plastic jar (or glass depending on the cleaner you're using) and put your de-greaser of your choice in it. And put the component you want to clean in the jar, and put the jar in to the water. The sound waves still pass into the jar and it still cleans just as well, but you're using less of your cleaner of choice.

[@philoso377]

Ultrasound builds up standing wave nodes and anti nodes, distribute across the 3D volume of liquid. Sound wave agitates the liquid then agitate chain metal, stain and surface debris. There are two important piece not often discuss about. 1) some minute and hard debris doesn’t sink to bath bed while machine is running, continue to stay suspended in the fluid by ultrasonic standing wave - acts like spotty sand paper on part surface. 2) distributed cavities (followed by cyclic implosion) can accelerate those suspended debris at the metal surface like sand blasting. Given enough time that can be our unwanted erosion. Shiny metal surfaces can turn into lava rock finish full of spotty and minute cavities, and in extreme case create irregular surface profile. I was there in my first run of a new cleaner.

[@jimjr4432]

I've used one for about three years on my bikes. When I start, say with an old chain, I soak it first in a can covered with white gas for a day or so, stirring on occasion. I then put the chain in the USonic cleaner. Simple Green is in the water. I don't start the USC until the lid is on. I usually clean it for a couple of cycles of 480 seconds. One might have to change the water once after the first round. I think the cleaners cost around $70ish USD. When the chain is dry, I soak it in melted paraffin, in a small electric crock-pot. I stir until the bubble stop and say another 10 minutes to be sure the paraffin gets in all the crevices. I love the system and have seen it affirmed on youtube videos. The chain seems to stay pretty, well really, clean. They say the treatment is good for 5-600 miles.

It cleans much better, the water is "softer" and it has more cleaning potential. 4th I prefer to take out objects while the unltrasonic device is still un operation. The dirt stays better in the bath and less on the object. 5th why just 51°C and not 60 or 80? 6th how do you get the water out of the last corner or gap? How about a flush with senatured alcohol or/and drying on a heater?

Oil, interested in your thoughts...from SRAM chain manual.. “Clean the cassette and chain with biodegradable cleaners only. Rinse thoroughly with water and allow the parts to dry, then lubricate the chain with chain lubricant. Lubricate regularly to extend the chain's service life. ⚠WARNING - CRASH HAZARD Do not use alkaline or acidic solvents to clean the chain and cassette cogs. Do not soak or store the chain or cassette in any cleaning product. They will become brittle and can break under load, which can cause the rider to crash resulting in serious injury and/or death.

[@tychoMX]

That's why Ollie is a chemist :). I'd feel safe doing what I know about the process and materials I use to clean and lube a bike (I have a minor specialty in material sciences), but also why a manufacturer's warning notice is very conservative regarding the advice they give for cleaning and maintenance. I'll give you a non-binding, non-prescriptive example: steel and aluminium alloys are essentially inert to solvents such as methanol, ethanol, acetone, diesel spirits. etc. But you can definitely get some corrosion with some other solvents. The problem is that aluminium is highly reactive to almost everything, but forms a passive hermetic protective layer on top (you're never looking at aluminium, you're always looking at the aluminium oxide layer on top). However, when the pH of your cleaner deviates from neutral this passive layer may be washed off, so you start getting corrosion. Conversely, even something like Dawn can present problems, because it is relatively high in chlorides - if it's not perfectly rinsed, it will often result in surface corrosion. I still use it (at least two dozen times in the fall; CX is messy) because it's very mild and fairly safe, but I make sure to rinse, dry and lube all the drivetrain components quickly after. Otherwise you can find a bit of rust (SRAM, Shimano and KMC chains all seem susceptible to this). So if in doubt, or if you don't accept the responsibility it entails, stick to mfr. recommendations!

[@voxmarsh6458]

Clean chain but now how do you clean the ultrasonic cleaner?

[@casualguy3938]

Dump out the container, then wipe with a cloth

[@AlanPB1968]

So Dr Bridgewood (the clean shaven Clark Kent to Oilie's Superman) whilst white spirit may have an autoignition temperature of over 200˚C it also can have a flash point as low as 20˚C. If the vapours find a suitable ignition source they will ignite. For perspective petrol typically has a flash point of below -40˚C and an autoignition temperature of >240˚C (weirdly higher than diesel at around 210˚C). On a serious note, putting neat flammable liquids in a heated bath outside of a properly protected facility is potentially very dangerous and a clean chain is not worth getting hurt or burning your house down for. I'd go with plain water or an aqueous degreaser solution.

[@JeffOehlsen]

Cleaning can be as simple as soaking your chain or cassette in gas, or rubbing alcohol. No need to spend money on cool gadgets, just get a glass jar, fill with gas, or rubbing alcohol, swish a couple times over 24 hours, and it does a better job, for cheaper.

[@chazpilks]

Would you use water with degreaser? I tend to with mine...does the job

[@G-rig6969]

Bought an ALDI one for A$30.. bit small as it's intended for jewellery but does the same thing just a bit small but fine for chain, cassette separately. I just put some degreaser in, but wouldn't hurt defeating and scrubbing it first to get most of the muck off, then putting in with detergent. Ps read the manual I won't put other coated materials in.

[@c799651]

In the past I wrecked a chain as I cleaned it so well with Kero all the internal lubricant was stripped. With this method what step are require to make sure this does not happen?

[@diesistkeinname795]

You ALWAYS need to re-lubricate your chain after cleaning it. Before lubricating it, make sure any water/solvent in the chain has evaporated as any mositure could get trapped in there. Use a lubricant that is capable of penetrating the pins and rollers, common options are oil (gearbox oil or expensive chain oil) wax (molten wax or dissolved). Give the lubricant a few minutes to penetrate and clean off any excess lubricant after that.

Mr T would love this video...

[@zygmuntthecacaokakistocrat6589]

Fine: I use one all the time in my workshop for drivetrains, and even rejuvenating tired 10 speed shifters, derailleurs, etc. HOWEVER: make sure you get a good warranty on whichever one you buy, as the transducers on cheap Chinese ones tend to cack out sooner or even sooner, and once that happens, it goes in the bin. I learnt that lesson at a shop I used to work at, and bought a good quality lab spec German-made one, with a warranty and service agent nearby. 10x the price of an eBay special, but it will last 10x longer, I'm pretty sure of it.

[@natdlareg]

Will an ultrasonic cleaner properly lube the chain's internals when you soak one with lube?

[@bernhardzach9686]

Be carefull with polished aluminum parts on dereillieurs and shifters - most of the time they are coated transparently which can start to come off by the cavitation and results in flakey white oxydation. Generally be careful with all coated parts and ultrasonic cleaners.

[@jamestalkscycling]

Can you use the yellow muc off bio chain cleaner/ drivetrain cleaner?

[@jaimeisreal]

I use WD-40 on my chain/drive-train in the winter. Works great. Gotta apply often though. But in the summer months, I use Finish Line Ceramic Wax.

[@casualguy3938]

I use it as well. WD40 works great, and in tests proves it is only a 2-3 watt loss over the very best waxes.

[@rogermanwaring1220]

It should be remembered that WD40 is not a lubricant but a protective film.

[@casualguy3938]

@@rogermanwaring1220 It actually "Water Displaces" which protects it from rusting. And if you wipe down the outside of the chain then very little dust adheres to it, preventing excessive wear. 18,000km on my current Campagnolo Chorus chain, and it still works fine. I have been simply spraying it on every 300-500km, wrap a towel around the chain and rotate the pedals backwards until most of it is wiped off. This leaves a thin coat outside, and the rollers wet. At the first sign of noise while riding, I repeat. Waxing is a bit more work, and better, but I am happy with WD40.

What size (how many lt) will I need to clean an mtb 10-50t cassette ?

[@philadams9254]

5:13 - just "bear in" mind. See what you did there

[@danlancaster2239]

Some comments below say it takes the grease out of the chain. Ummm, I didn't think grease was in chains, that's why you use oil or wax for your chains. You have to remove as much grit from your chain or the chain acts like sandpaper to your cassette and inside the chain racers.

[@tychoMX]

there is a manufacturer, factory applied lube on the chain. Whether you call it grease or oil is probably semantics. For my usual chains (KMC) it is a pretty thick compound!

[@EtienneDionMarcil]

Can you wash disk brake pad the same way? Mine are contaminated.

[@nyccanuck8692]

What ultrasonic unit would u suggest?

[@petinka721]

Ollie look very clean! Do not let Si lubricate the chain!

[@christophermee5214]

Way over the top pal

[@remotecontrol9874]

Good show. I used to use the microwave to clean the chain and cassettes but the explosions prompted the wife to forbid me from entering the kitchen. Ultrasonic is better.

[@adrianaprhys]

In the US, white spirit is called mineral spirits. I had to look it up, because I thought you meant vodka or moonshine.

[@Alex-kr7zr]

Cleaning Benzine does an excellent job degreasing for a cheap price. White spirit leaves some residue, so not ideal. Also worth mentioning that the ultrasound cleaner needs to be filled 3/4 so that would use a lot of cleaning fluid, better to fill it with water and put the components in a pickle jar or ziploc bag.

[@martinberry1540]

What about waxing the chain, see Oz Cycles video.

[@casualguy3938]

Yep. Wax your chain after this and you'll be good. I use WD40, but both are good to apply after a proper cleaning

[@srpskihayk]

Oh, I must be old. In a technical drawing class I took long long ago, we used these cleaners to clean our pens. They could not stay too long in the machine, as the flow control wire would get damaged. Maybe that is true or not. Maybe the instructor just did not want us to leave our pen parts in the machine.

[@SleepDisorderedBreathing]

Downside to these baths is that they are loud! I have one and I don't think I can use it in an apartment complex. Im with family now so I can use it in the garage but when I move out Im not sure how the neighbors will take it

[@AirSpace]

Have you tried re-lubing with hydrogenated oils for margarine-al gains?

[@julianallen515]

Is this the new presenter? He looks kind of young! ;-)

[@R_C420]

They also clean spectacles. Even fake ones. And vape paraphernalia. I wonder - if you put a clean chain in an isolated container full of lube then put that container in the sonicator.. will the lube work it's way into the chain gubbins? Then it could truly be like new.

[@robincooney1263]

I have now stopped using my ultrasonic cleaner for items with friction joints e.g. rivets. So cassettes and chains. Over time the ultrasonic cleaner loosens these joints giving premature wear of the components.
