Default Re: cleaning aluminum cases without disassembly.....any ideas??

I just used some aircraft stripper to get the paint off a set of cases. It worked great. Brushed it on, let it sit, scrubbed it off with a solvent brush. Be careful though, I also took some paint off my bike lift too when I spilled it on it.

Brake cleaner first, then soap water and a few good stiff bristle brushes. Rinse and you're done. The 99 cent store is your freind in times like these. If you get lucky you can even find brake cleaner there.

Speaking from experiece on this one, the oven cleaner does not work. I left some aluminum Triumph parts in some purple cleaning stuff that turned them black, so I followed some JJ advice and tried the oven cleaner which did nothing- even after a few hours. +1 on the walnut shell blasting though.

Aluminum wheel cleaner works great, oven cleaner DOES NOT work on aluminum, it has lye in it which causes aluminum to turn black. Soda blasting would be best, or walnut shell second. I've had good results with Bon Ami® cleaner and a stiff nylon brush, the sink will get clean after too.

Default Cleaning cases without etching or blackening

I have my bike torn apart and Im cleaning the head and the cases, trying to make them look like new before I rebuild. So for cast aluminum I have always used Brake cleaner or Orange Glo. I dont want to use anything that will etch, blacken or rough up the outside of the cases like Acid or sand / glass blasting. Any other recomendations? I always had my engines and heads hot tanked on my cars.. can the same process be used for aluminum?

So post all your cleaning, paint removing and degreasing tips and recipes. What even you use to keep you ride looking nice.

Vapour blasting, or whatever it's called in your neck of the woods is the way to go for bare alloy parts, WILL NOT remove chrome or other finishes from parts, can restore bits with good bearing/machined surfaces to usable condition and leave them with a natural cast looking finish.

Thanks for the info. I was looking into Vapor blasting but my cases are covered in over-spray, gasket sealant, oil and just about everything else.

Wow, alot of info here, i just went to the auto parts store and bought some engine degreeser i think it was a cittrus based product. Spray it on let it set awhile and lightly hose it off, worked great. Now my engine was just oily and road grimey, not etched or anything like that but it did work very well. Also used a citrus based product on a old aluminum oil bag on the inside, rinse and repeat a few times, clean as a whistle.

PM TroyFab for the name of the guy he used to get his heads and cases done. Some kind of shot blasting process. I've NEVER seen such a clean job in my life.
