Super Clean Aluminum Engine Parts

[@killerguitarvoodoo]

After cleaning and polishing several aluminium parts and wheels I've found it's not the solvent necessarily but the brass brush is the real winner here. It really does a great job.

[@smore1g]

Scotch brite and some elbow grease is also extremely effective

[@TREXautoservice]

I remember years back....filling our new parts washer with a 5 gallon bucket of Purple power. LOL. It ate the aluminum pump in the tank.

[@thelegendaryblackbeastofar39]

I personally have had poor results using purple-power on unfinished caste-aluminum parts. It cleans caked-on oil/grease very well and the parts look nice and clean. I few days later, a white cruddy powdery residue starts appearing on the surface. Looking through various automotive forums, this is a very common experience with Purple-Power. Thorough scrubbing of the part with detergent seems to remove the crud, but it eventually comes back. From what I gather, it has to do with Sodium Hydroxide (the active ingredient in Purple Power) getting into the micro-pores of cast aluminum and causing a reaction.

[@rockymntain]

Sodium Hydroxide in solution will turn all aluminum black.

[@michaeljayfawkes2414]

That's corrosion. When aluminum composites corrode, that's how they do it. Over years that powder becomes deep pitted holes in the surface. Water makes it happen much, much quicker, but because this is an engine part the heat probably prolongs the life of the part, slowing the reaction down considerably by flash drying it with regular use. For another fun chemical experiment, you ought to drop a drop of gallium on it and wait overnight. By the next day you'll be able to fully demolish the part by hand and it'll be made entirely of that powder because of the way gallium bonds with aluminum.

[@thelegendaryblackbeastofar39]

@@michaeljayfawkes2414 Yes, automotive aluminum does corrode in the real world but it is generally accepted to be cosmetic rather than structural on nature. Pure aluminum passivates (ie forms an impermiable oxide layer that protects the metal underneath from further reaction). The white powder (that I've seen forming after using Purple Power) is very different in consistency from the normal corrosion that forms on typical alluminum alloy surfaces. Natural corrosion residue is much harder, forms much slower and is characterized by pitting. I've never had the white powder chemically analyzed but it matches the physical characteristics of Sodium-Aluminate (NaAlO2 or NaAl(OH)4 in hydrated form) very well, a soft white fine powder formed when an aluminum surface comes in contact with sodium hydroxide (the key component in Purple). As bad as gallium is for aluminum I believe mercury is even worse. I remember hearing that it is prohibited to transport mercury on planes.

[@sfdrcm]

I think the trick is to not let it sit on the part. Spray, scrub, rinse, rinse, rinse.

[@michaeljayfawkes2414]

@@sfdrcm Agreed. LAs Totally Awesome also works quite well, and I haven't had the corrosion issue. The original yellow one, mind you, the orange one messes up aluminum in a matter of 30 minutes.

[@misterfixit1952]

I read a study on the top 10 grease and oil cleaners and Purple Power was number 2 behind a $20/gal brand. At less than $5/gal it is my favorite parts cleaner but definitely don't leave aluminum soaking in it for a long time. 5 or 10 minutes and a good scrub will do the trick. Although it does leave a dull gray finish on aluminum, you can polish it up as much as you like afterwords.

[@daveg2199]

Here in Wisconsin at the farm store they have whats called power team acid rinse. Its thin pink sprayable liquid. Its a blend of phosphoric acid and sulfuric acid. Are used it on my pontoons and it was amazing! It brighten them up very well but didn’t cause any kind of pitting or etching. It’s only eight bucks a gallon! spray it on and let it sit for a few minutes and rinse it off! I’ll be doing an aluminum canoe next!

sir this purple power also does radiator flush great my truck was overheating with lots of rust and i mixed it with half a gallon of water let my truck idle for 15 minutes.. wow it did the job no overheating anymore i was impressed i didnt have to take radiator off to get it cleaned .. so thumbs up for purple power work amaizin. so it work better than having to buy at an auto store radiator flush when u have it right at home thanks you

[@pantherplatform]

That's the same stuff I use! I soak my aluminum parts in a mixture of that and hot water overnight and it literally melts everything off. I would recommend using a paintbrush when rinsing them to help get all the residue off.

[@MikeM-ld1rw]

Another great video. Thanks Dale! That purple stuff is great. I just used it to clean my block to help me track down and oil leak.....Half of my valve cover bolts were loose! I torqued them all to 85in/lbs and leak is gone! Glad it wasn't my RMS! Its nice to fix an oil leak in 10 minutes! I appreciate the easy ones.

[@JeepSolid]

Thanks man! Yeah, the easy ones are always nice wins!

[@JeffHucik]

My buddy who has only worked on irons block engines told me to put my aluminum LS block in a purple power bath. Left it in for 2 weeks and when I pulled it out it had eaten at it and the Block was shot. On my second block.... I used a pink aluminum brightener which consists of hydrochloric & Phosphoric acids. Wet surface, spray on, scrub in with soft brush, & let sit for 10 mins and hose off. Rinse and repeat until desired clean. It takes a few times but gradually you’ll get your desired level of clean. If you have smaller alum parts, I use Berryman Chem-dip. Amazing stuff.

[@ct1762]

the chem dip is incredible. nasty stuff so use outside of course but even in freezing temps it literally dissolved oil and grime.

[@theadventuresofdk]

Most products like this contain hydroxides. Purple Power has it listed on the material SDS. Aluminum is generally a reactive metal and hydroxide (OH-) can dissolve away the protective aluminum oxide layer. A better alternative would be elbow grease + a biodegradable cleaner like simple green. Highly recommend diluting products like Purple Power and minimizing the amount of time it spends in contact with the surface of the aluminum.

[@strongman86]

Purple Power cost me a timing cover and ac mounting bracket!! thank you for letting others know about this!!!

[@theadventuresofdk]

@@strongman86 I don't think a lot of people know or understand that a strong bases (like sodium hydroxide) eat a lot metals just like a strong acid (think hydrochloric acid that you might see at a hardware store). I think there's a misconception that if something is sold in a plastic container, it must be safe for metals. Not that anyone would do this in the automotive world, but bromine reacts with aluminum as well, pretty violently. It's one of my favorite lab demos. @mtsuchemistry

[@LandyAndy62]

I always use a rotary wire brush - just lightly, but it takes off all the oxide which is what holds the oil/grease.

[@vernonbosshard9317]

A fine brass wire brush is ok but not for gasket surfaces, a large machined flat block of alum and PSA 320 on it does a good job.

Nitro Force for R/C cars is hands down the best cleaner Ive ever used. Spray that stuff on, and the hardened dirt grease and grime just falls right off.

[@hussssshie]

My trick is usually spraying some brake cleaner, letting it sit for about 30 seconds and then hitting it with a pressure washer. Never found any grease stubborn enough with this method. As long as the surface is not painted, the aluminum should be perfectly fine without any etching or discoloration

[@tylerseabook9423]

Toluene, its used as a degreaser in aeronautics machining. Aluminum and carbon steel safe. The only down side is the fumes make sure to use it out doors or in a big open space with a fan.

[@sonicgroovesi]

been using purple power for 10+ years as a detailer, be careful if it sits on the aluminum too long it can turn it a real dark gray

[@richardschmidt6619]

Years ago I had used the Amway Industrial Clean mixed 50/50 with water. I the part soak overnight in it. Took it out the next day rinsed it off. The part was clean as brand new. And, with no scrubbing. It you used it with steel parts, you need to spray it with oil or rust would start on it.

For car parts, I use Simple Green in various ratios w a toothbrush and the brass brush. Covers 90% of my needs. When this isn’t enough, out comes Purple Power.

[@parrot69777]

Back in the day we use to soak all aluminum things (pistons, covers, etc.) in carb cleaner. That was before the EPA got involved and now everything sucks. ZEP industrial cleaner in a boiling tank works good. Have tried the purple stuff too. Once I get the grease/oil gone....I use a sandblaster with 50% silica sand and 50% glass beads to finish it up. Some people blast with walnut shells.

[@bernhardlist9359]

Hi, I cleaned all my aluminium parts in my vapor blaster but blasting the grease works well and fast but it makes a huge mess in the blaster housing so recently I started using a handheld blaster (25U$) with soda and preclean the part out in the garden (get good protective glasses) since the baking soda is environmentally safe you can do that in the lawn. Afterwards I blast it in the vapor blaster with glassbeads which brings great results and a smooth surface. Ok, you got to rinse them really well with warm water and dishwashing liquid to get any of the beads out especially out of thread holes that tend to fill up. When dry I use compressed air and go over it once or twice until its has no beads left.

[@occamsrazor1285]

4:50 There's something I use as a "first step" (won't get it completely clean, but does as well as this Purple Power stuff); think about what grease is. It's an emulsified oil. An emulsion is any dry material that is mixed with a liquid, but only enough liquid to make it a high viscosity liquid (and not a low viscosity. Basically more of the solid than the liquid). Grease, the kind of grease we're talking about, is solid carbon mixed with liquid hydrocarbons (oil with carbon soot). Now, what cleans up grease really well? Like when you need to repack a wheel bearing and you want to get all the grease (that's been further emulsified with dirt and rocks) out of the bearing? Mineral Spirits.

Years ago, I took a really gross aluminum intake manifold off a diesel V8 to a motor machine shop and had it cleaned it in a hot tank. The guy left it in there about 40 hours. It looked brand new when I got it back. Another method is to blast it with walnut shell abrasive.

[@larrywoolford8978]

The white residue is just aluminum oxidation , that just what bare aluminum does over time . This may be considered cheating , but what I do is spray the part down with engine degreaser, then pressure wash it really well , then dry it with compressed air , clean any grease or oil left on with a nylon brush and replete the engine degreaser , pressure wash and dry cycle ,then go over the entire part with scotch brite to scuff it up then paint it with aluminum engine paint . I know this isn’t exactly restoring the aluminum to its original condition , but it keeps the aluminum looking brand new for years and is really easy to keep clean .

As of todays date, August 26, 2019, you can purchase 1 gallon jugs of Purple Power concentrate at Walmart, for $4.87 per jug. This is concentrate and can be used to make up to 20 gallons of house hold cleaner, or 2 to gallons of heavy degreaser, depending on the severity of grease/oil you are dealing with. I find is works best as 70% concentrate, 30% water for most all heavy degreasing jobs. 100% pure is serious stuff. Ive used it as a 3 day pre-soak on a BMW engine that had a several year leaky timing change cover, and valve cover gaskets, and power steering unit...pretty much a black coated engine block and under carriage. I sprayed concentrate on the engine, hoses, lines on 3 occasions and pre-soak. The final day i mixed 1 quart of diesel with 2 quarts of purple power and 1 quart water, and soaked same areas 15 minutes before taking it to car wash, to spray off all grease. No lies, every sign of leakage, stains, discoloration, grease or oil washed off without having to scrub anything and all metal parts looked like nearly new metal, hoses were like fresh rubber, lines looked nearly new, no yellow or brown hazy stains... Almost like new metals.... I've been using purple power since 2003. Don't use it on polyeurothane clear coated anything. Great for removing stains from carpet, clothing, washing work clothes, cleaning concrete... Its good stuff!
