Geeto67 Posted January 14, 2015 Report Share Posted January 14, 2015 Hey All, So I have these aluminum motorcycle racing pistons. They were in great shape when I got them but I had them stored in a bad part of my storage locker in NY and it looks like an animal got in and pissed on them (smells like it too). Since they sat like this they corroded where the urine was. I have washed them but anybody have a good suggestion about cleaning the corrosion? Do the finishes have to be machined, or can I just hit it with an emory cloth (like a scored piston) and then polish them? They are really rare and I would hate to have to toss them in the trash because of this. Thoughts? (beyond the usual don't store stuff where animals can pee on them).

Cordell Posted January 14, 2015 Report Share Posted January 14, 2015 If there is any pitting or porus spots where you can't polish it to like new you might as well consider them ruined. If you want a final say take it to a machine shop and ask if its any good. Quote Link to comment Share on other sites More sharing options...
