aluminum cleaner
« on: June 23, 2007, 04:14:58 AM »
What is the best thing to remove oxidation from our aluminum engines with?
I don't want a polished look, just a non-blotchy even clean look.

I'm not tearing the engine down and have done a few parts with that
acid wash cleaner which works pretty good but I don't want to
spray the whole engine with it. Some sort of paste cleaner
is what I think would work best, and a tooth brush :)

Remove covers from the engine. You can do this procedure w/ covers on engine in frame but you'll get better results w/ a little dismantling. Chemically zip-strip the factory clear lacquer, then etch them w/ hydroflouric acid (Mothers Wire Wheel and Chrome Cleaner) while rubbing w/ 000 steel wool then rinse w/ plenty of water. Now polish w/ 000 steel wool w/o adding any polish paste. You can give a final rub w/ 0000 if you want a finer finish. Use Penetrol as a polishing lube, which also works to rejuvinate nuts, bolts, plastic, metal, and frame paint. You can clear w/ Eastwood metal clearcoat in a rattle can, which will add some durability and will approximate the orig clear. Or leave the aluminum bare and rub once  or twice a season. DEFINATELY wear HD rubber gloves and eye protection when using these harsh chemicals!
You will be more than happy w/ the results. I use this technique when I want to give the motorcycle a super-clean original "unrestored" look, which is compatable w/ original paint, chrome, gauges, spokes, nuts, bolts etc.

Hey that's the look I'm after. Don't want it to look to restored just cleaned!
Thanks, Robert

it doesn't look like you have had any ill effects from applying steel wool to aluminum, which i thought i remembered reading here would lead to steel particles oxidizing the aluminum, or accelerating oxidation where the particles are left in/on the aluminum.   ???

Hey Klark, you still heading down this way? If and when be sure to holler at me!

I used steel wool on my wheels and it really cleaned them up great.

hey RM
i wish i had more free time when i was in VA.  i spent about 3 hours a day awake where i wasn't working or riding to/from work.  Made a good pile of dough, so now i have some free time and might revisit the area for fun- and if i did i would head straight for the mountains, so I'll let you know.- today would have been perfect for a trip like that- damn hangovers...

anyway about your polish question, steel wool is great on chrome(ium steel) but that is steel on steel, and i might be mistaken (i'm the one who wet sanded his chrome) but i could have sworn that i read steel wool would leave little specks of steel in the aluminum, which would lead to white specks of corrosion popping up.  but 736cc's bikes all look so badass that i am questioning this....  :-\
