I have my 406 small block out for some painting I did on the frame. I decided to paint the motor and clean up all parts. My rpm performer looks like crap and I was wonder what to clean it with. I have it off the engine so it can be soaked it needed. I was considering soaking it in peroxide. I was told that cleans aluminum up real well. I am putting on some AFR 195's and want to bring everything up to par so i can hit the remaining summer car shows.

i cleaned mine with some degreaser then used brake cleaner on the tough sopts. worked pretty well. i ended up painting it with hammer paint, looks pretty cool.

Try some paint stripper from the auto parts.
Stuff I got was from NAPA and was water soluable.
Spray it on, wait for a while and then take a brush to it. rinse it off.
If it is oxided aluminum, this wont make a difference much. If it is gas stained, it cleans pretty well. I also found some high temp aluminum paint in a rattle can. Sprayed the engine of my Gold wing. Looks just like the factory color originally to give you an idea. Got it at Murrays Auto Parts. If your interested, I will get the exact name of the stuff. Just email me.

If you have access to a blast cabinet with glass beads as media that can do a great job.

Simlpe Green & hot water

Spray the intake with mag wheel cleaner. Eagle One makes a good one that will give you excellent results. I used the etching spray. Worked great! rb6667

Plain old laquer thinner works fine

We have all kinds of thinners and chemicals at work and for some reason carburetor cleaner in particular works the best.
