Phosphoric acid, you can get it at a hardware store as ospho. or go to a auto supply store and look for mag wheel cleaner for un-cleared wheels.
It will have phosphoric acid as the main ingredient.
Spray it on let it sit and then spray it clean with water.
It is great for aluminum.
I got my motor all cleaned up & was going to spray it with brake cleaner then paint it black but when I got to the garage it & the bike were all wet from condensation so I let the bike dry off but when I looked at the motor it had little specs of white stuff all over the alum its kinda like powder
cant paint it like that so I have tried to spray it then blow it off but nothing seems to get rid of the stuff I have seen this before on alum anybody got any ideas how to get rid of it with something besides a brush ????????
