I am cleaning my second rotor for my rebuild. My first one cleaned up really easy, but the second I have been soaking in Simple Green for 3 days now, occasionally scrubbing with a scotch brite pad. Most of the carbon came off of the faces but there is still large spots (combustion chambers) on the rotor that are caked and it wont come off. WTF do I do to get it off without messing up the rotor?

Try stronger degreaser, like purple zep. Or scrape the cakes off w/a brass brush by hand, or the tip of a razor. Then a scotch brite pad. It's just work, and simple green can eat the metal if I remember correctly. Hope you replace the bearings. Although I could be wrong...later

Die grinder with a wire brush bit.

Go to home depot and get two big cans of mineral spirits. That stuff is the best.

I would avoid power tools to clean rotor faces, because I really don't want to change and compression ratio's. But that's just me. But I bet you could do it if you are in a hurry, and went lightly.

a rag with a little ATF, its like the ATF trick, without the ******* up your engine part. just dont get ATF on any seals or anything.

I use a razor blade and a wire brush with some brake cleaner.

really? Don't use that envermently freindly brake cleaner, go strait for the one that gets you high in a few seconds... I never had much of a problem getting carbon off with brake cleaner.. can't think of the brand I use off hand though.

i suppose if you put a rotor in like, a clam steamer, you could technically steam the carbon off coudlnt you?

Wouldnt a wire brush scratch the rotor face?

thats why they make NYLON rotary brushes

Pressurized mineral sprits in a sprayer. Like use a paint gun that works good. Or this kitchen cleanind stuff called Tornado. Let it soak for like 10min in that pull out and while wearing gloves wipe away. THat stuff will kill your skin if you anit used to it. It dosnt bother me anymore though.

Just use the mineral spirits in a bucket and soak it for a day or two... everything will come off like it was just laying on top. Have some carb cleaner to blast off loose particles, and some compressed air to dry everything.

I dunno.. what worked for me was Carb cleaner.. use getr enough bottles into a bucket and let it soak.. I got everything off that i wanted to, it was nice a shiney after...

Nitrometano

Soak the complete rotor into Fuel Injector Cleaner, the GM (General Motors) is the better but, other are ok. Soak it a few days. Then use compressed air and all the carbon will go off.
