[@kandiepunk]

if doing any tank restoration and your nervous about using the acid, i can definitely say that white vinegar works really really well, i left in a 84 virago xv1000 tank with medium to heavy rust for 2 weeks. then washed out and used red kote (tank sealer from oreilys) now the tanks good for another 20 years at least.

[@Eskareignneo]

kandiepunk did you wash it out with just water?

[@colleenegan1961]

Dont mess around with muriatic acid. It's terrible and eats the metal. White vinegar is like $1 a gallon, super cheap, use it, no damage to your skin or surrounding area and you can pour out anywhere. It's all you need. This kid is doing overkill.

I used muriatic acid on my 78 gs750 tank. Shit works amazing, i used a pressure washer on the inside to get all the acid out, then sprayed WD-40 to prevent any flash rusting. Still rust free

[@sixtyfiveford]

Awesome.

[@bmay8818]

Ardent Fan Drain cleaner is a strong base, the opposite of an acid, so I doubt it would work the same.

[@slantsix9783]

Ardent Fan: Your are correct in saying that drain cleaner is a strong base. However, not always. Sulphuric ACID drain cleaner, although not as readily available because it's more dangerous to handle, IS NOT a base.

It is not difficult to find HCL at all. You can find it anywhere they have pool supplies. It comes in 31-33% strength and it's the strongest you can buy. Paint departments at hardware stores also have the same thing, but at the big box stores it is often sold in 15% strength.

[@nunliski]

Or you can just buy some muriatic acid, which is hydrochloric acid lol

When the acid has eaten all the rust, it starts on the clean metal. Limit the soaking time.

[@wyattoneable]

With the cost of steel gas cans these days it's worth a little work to keep those going. Nice one!

[@kenpoq4]

+1970chevelle396 They're great tanks as long as water is kept out...

[@Azazelwalk]

I started out (before I properly educated myself that is) trying to clean out my motorcycle gas tank with CLR. Left it three days, emptied, inspected. Poor results. Then tried vinegar. Poor next to no results. Then went the electrolysis route: mixed results. Only "pulled" about 50% of the rust out. Tried for longer time period, still unsatisfactory. Then I tried this... poured a 50:50 acid water ration and immediately saw it chew off some rust I couldn't even scrape off with my finger at the inlet of the tank. Gonna leave it for 24 hours. Excited...

[@sixtyfiveford]

It's strong stuff.

[@theSword-]

white vinegar used at 50%/50% with water is a very effective ratio and works great.

[@rronaldreagan]

vinegar 100% is too much? i was planing to use vinegar and some bolts as recommended in the video with my metal bike fuel tank

[@theSword-]

don trump 100% vinegar works but the 50/50 mix is equally effective and water is free. If you try it and think it needs more, just dump more in. I use it at 50/50 and its great.

[@rronaldreagan]

MGTOW KNIGHT thanks, ill try it soon. Did you coat the surface afterwards with something? (to prevent rust in the future)

[@theSword-]

Yes, you have to rinse it really well with water, then dry it before it can rust, then spray primer on it. If you are coating the inside of the tank, I read on the back of the "chassis saver" can that it is oil, solvent, and fuel resistant. I haven't done it yet but I will. "Chassis saver" is the same as POR15 but about half the price. It's on Amazon.

[@rronaldreagan]

MGTOW KNIGHT are you sure those 2 products are compatible with gasoline? ive been researching them and they look like thick paint that is applied to exterior surfaces only.

[@eamonnmckeown6770]

last year I was able to get a good price on two gallons of evaporust to use on a Yamaha Vino tank. It's pricey but the tank is only 1.2 gal and it did work. I just priced Muriatic acid. Definitely a lot cheaper. You can dilute it and it is infinitely more reusable it seems. Oh well.

[@elgilligan6616]

I heard you can put a bunch of ball bearings in a can and put it in your car for several weeks/months and it will knock the rust down.

[@vorkev1]

what you can do also at the end of a acid wash is flush the tank with a hose yes water pref hot then when dun to get rid of the water past use rubbing alc of if you are in in a hury let air dry.

[@GTVAlfaMan]

What do you think of using EvapoRust on a rusty gas can? EvapoRust is safe to your skin and eyes and also removes the rust safely. Also, it can be reused many, many times over.

[@sixtyfiveford]

+Buick Mackane I' m sure it works, just slower.

[@Schralenberger]

Working from the point, that you've decided they are worth all the effort(and that it's a moot point,that they would be easier to replace.):Perhaps you should change your approach. If this were my project(and it's not. so yes it's indeed your opinion that matters here not mine. I will apologize right from the get go.) I would turn this in to a welding project. First, just cut all the bottoms out to start with. Carefully avoiding the rolled edge seams(where the bottom meets the sides.) . Just cut and knock out, the centers. Then just sand blast them clean(inside and out.). Then, just mig weld an 11 gauge steel bottom on(placing your weld on/around the bottom.) Just search out any pin holes, and weld over. A much easier approach. The important thing(to state the obvious.) is that they are watertight. Though you should still be able, to get a cosmetically acceptable seam on bottom.

[@sixtyfiveford]

+Schralenberger You still have to rid the inside of gas vapors that have buried themselves into the steel before you weld/cut. An acid wash does just this. Welding up a few pin holes or a small patch is much more considerable than an entire bottom. I would guesstimate these at around 18gauge and you know what a pain they can be to weld without just doing stitch spot welds.

[@dennissobey4573]

Great video...Thanks... I need to clean my Model A gas tank. Replacing it is a no as the car has been freshly painted and I do not want to remove the whole cowl. gakkk. I am guessing this would do the trick. hard part would be the sloshing around but I think the rust is mostly on the lower part so perhaps just putting a couple gallons in. anything I should be aware of other than the acid being acid and being sure to neutralize after?

[@sixtyfiveford]

Just watch it closely as this method is pretty fast. If you leave it too long it will start to eat good metal. Be prepared to dilute it and or neutralize it. Also, be prepared for your petcock to get clogged multiple times with chunks of rust.

[@FontediCalore]

I find that vinegar will eventually remove all rust and will not harm the metal. For instance I had a rusty motorcycle drive chain that was almost neww no mileage done but it was seized tight and covered with rust after some 40 years in the rain, after a month in the vinegar it came out clean, no rust on it, all rust melted away in the bottom of the bucket.

[@sixtyfiveford]

True, it's just slow.

[@theclaros6521]

Ok so i did it. Worked amazing. One hint of caution. Watch how fast you add the neutralizer. Mine was like a mini volcano lol. Otherwise it looks great.

[@sixtyfiveford]

That's great, I'm glad you tried it out.

[@thomasgronek6469]

'Varnado' toilet bowl cleaner, and 'The Works' toilet bowl clean are each 20% HCl (Just in case you can't find anything else, , , ,but check the label, they might have different formulas)

[@LelouchVelvet]

Wouldn't not mixing HCl with water have much faster results?

[@sixtyfiveford]

Yes, but it is extremely strong to begin with and adding water just lets you contact more surface area inside the tank.

Before you mention gas tank liners, I was actually going to suggest that it. Idea for that wrecked gas can, make it a safe if you think about it, if someone break into your shop, most likely they wouldn't grab a rusty old gas can so you could hide stuff underneath it.

Muriatic acid is sold at pool supply stores, Home Depot and Lowe's also sell it in the garden departments out west.

[@earlyculyer4103]

How about sandblasting? Or media blasting?

[@36barnstormer]

Careful with Muriatic or Hydrochloric acids, instead go to Lowe's or HD and buy Klean Strip Concrete and Metal Prep for about $18 a gallon (April 2021). Cleans, converts and doesn't keep eating the steel like the aggressive acids. Clean, let the acid sit overnight, drain and use baking soda and water to flush (or just alcohol) and dry with your leaf blower. Then coat the inside with POR-15.

[@BigFarles]

Thank you. Great video. Have you ever rebuilt a diaphragm pump. My pump in my camper new replaced or rebuilt and I'm not sure which way to go.

[@sixtyfiveford]

+Marcus Kloepping I have torn them apart before. The one I was trying to do I couldn't find a rebuild kit for. Years, ago they used to be $100+ plus but I just checked Amazon and some are only $20-30 for a complete new pump. The weakest link in a cheap pump is going to be the electric motor. So If your pump has little use and not rusted I would rebuild it if it was cheaper than a new one.

[@kirkjohnson9353]

Great demo- thanks. I have a CT110 motorcycle that needs the tank cleaned. It is not real bad but I want it to be dependable and stop the rust. Do I need to use a tank liner like POR 15 if there are not yet holes or deep pits? Will the rust stay pretty much stopped if I keep using fuel with no alchohol in it? -- A friend of mine turned a gas can like that into hitch hiking "luggage" by putting a bottom on with snaps. Standing along the road with a gas can is a good way to catch a ride.

[@sixtyfiveford]

+Kirk Johnson Just flush it and you're done. I wouldn't coat it unless you had a hole. Keeping the vent closed on the Hondas and ethanol free fuel will prevent rust for sure.

[@shalakadasari9938]

Will this acid affect the welding of the tank? How much is the soaking time? How much amount of baking soda and water have you added to neutralize the acid?

[@sixtyfiveford]

Acid affect welding: No. Soaking time: depends on acid concentration and rust severity. Baking soda: You can't use too much; go until you so no more bubbles/reaction.

[@RedDawg2k]

I would highly recommend not sniffing the tanks after muriatic acid has been present. A big whiff and your sinus can be burnt from the fumes. I know a kid that found a cup of it on a job site and it took months for him to recover.

[@pixelpatter01]

Putting the acid and water on steel will generate hydrogen gas. It's not that big a deal but then you tightly secured the cap and pressure will build. HCl cleans fast, eats sheet metal fast and rusts fast after it's rinsed off. IMO you can never get it all off and the metal will always rust at an accelerated pace after an acid wash. The fumes will make all your steel and iron in your garage rust too.

[@maciasrick454]

I pulled my gas tank off of my sidekick that sat. It had fresh gas which I emptied out. Should I flush with water and let dry first before I do the muriatic acid and water method?

[@sixtyfiveford]

[@57WillysCJ]

So it'll be my first time using this method. I Need to clean a rusty 5 gallon generator gas tank. What ratio would suggest? maybe 2 gallons acid, 2 gallons water, water in first, slosh it around for a bit with some marbles or rocks or bbs? Rinse it out and then a quart of diesel sloshed around to coat the tank? Does this sound about right? Then neutralize with baking soda and water? Anything I'm missing

[@sixtyfiveford]

You can reduce the amount of acid it will just take slightly longer. So 1 gallon acid and fill the rest with water.

It is great because it only eats rust, doesn't eat the metal -- works very much like phosphoric acid does: only eats rust, and leaves a coating that won't flake off the surface and that doesn't have to be removed. Also even lower cost than the very affordable phosphoric acid. Not as hazardous as muriatic acid though it should be used like muriatic acid -- in an open area or with positive ventilation.

+Sean Flanagan Interesting. I've never heard of oxalic acid.

[@seanflanagan5674]

+sixtyfiveford I hadn't either. I was going to use the potato method but my trusty Ace guy got me to try phosphoric acid, which does work great but is a bit pricey. Did a search for bulk phosphoric acid and stumbled into some forums for hot rods, with tons of info on restoring vintage cars. Learned about oxalic acid and its benefits, such as not eroding the metal; option to leave parts in the solution for very long periods if that was convenient, etc., but the clincher that compelled me to try it was a thread about leaving a frozen hinge in the solution for some time and taking the hinge out and it moved freely. Found a very, very good price at an eBay vendor, Florida Labs: www.ebay.com/usr/floridalabs?rt=nc I recommend you give it a try.

[@sixtyfiveford]

The phosphoric acid is the main ingredient in Navel Jelly, that is readily available at most stores. I will give the oxalic a try.

Wouldn't these cans be great candidates for electrolysis?

[@sixtyfiveford]

Electrolysis doesn't work well on oily parts. Gasoline is an oil so if there's any remnants of gasoline it'll probably deter electrolysis from happening.

[@cpoul]

​ I had seen someone on youtube use electrolysis on a cast iron pan and all the caked on buildup came off and the pan looked new.

[@snapfly7]

did you neutralize with water or vinegar?

[@sixtyfiveford]

Baking soda and water.

[@slv_car_refinisher6864]

@@sixtyfiveford bro I did this in my fuel tank of 1978 datsun.. I put a gallon of muriatic acid inside I kept sloshing it for a 15 minutes, I was so happy with the results. White, clean bare metal, I put a pound of bakin&soda and a gallon of water did the same thing sloshing it everywhere, I put only water after drain the solution. I was more focused on get rid of The remain baking soda powder, I put a quarter of paint thinner.. And I drained it and as soon as I closed my eyes is was flash rusted so bad,,, now I have it with a Phosphoric Prep and Etch..a gallon from home depot. I'm going to keep rotating it every single day to get all the spots and corners.... The only thing I dont know is with what the hell am I supposed to rinse it,since some people say dont rinse with water and others say just let it dry by itself. Any thoughts? please it would help.

[@gregblack2628]

Thanks I got 2 generator and tractor. Wish me luck

[@MidwestMotoRider]

Nice, those came out nice!

[@sixtyfiveford]

+MidwestMotoRider Thanks for watchin man.

[@baitsandbullets5283]

will the acid attack the paint on my tank?

[@sixtyfiveford]

It probably wouldn't be good for paint if left on it for an extended period. But I doubt it would harm the paint if it contacted it and you neutralized the acid with baking soda.

[@matthenard]

Ah man, wish I would have seen this video a couple years ago. I did the apple cider vinegar with nuts and bolts and it did not work well, left it for 48hrs. This would have saved me a lot of time. Thanks for the video, now I know!

[@sixtyfiveford]

+SLO70 It seams to work within a few hours. It does need to be watched though as if it sits too long it will start to eat the metal.

[@c50ge]

Clean it with acid/water first just like the video. Throw some nuts and bolts in it strap it to the rear wheel of your truck. Jack the wheel off the ground. Idle in drive for 20 min. All will be shine (I use my small tractor)

[@Paul-hn1wo]

Use a pressure washer to clean the varnish off the inside. That's the yellow stains

[@chargermopar]

After cleaning I like to electroplate the inside of my gas tanks using junk D batteries. Battery acid recovered from junk batteries works well for electroplating.

[@bobjones1131]

Need a video on that.🤔

[@TheChipmunk2008]

Ebay is good for chemicals too, fairly cheap

[@sixtyfiveford]

+TheChipmunk2008 Good tip.

[@steventaylor9016]

Great video! I had a question, how much muriatic acid per gallon would i use for a 11 gallon gas tank? Thanks.

[@sixtyfiveford]

The more you use the faster it works. I would probably use 1-2gallon acid with the rest water. It will take probably around a day to fully remove all the rust at that ratio.
