My son just turned me onto Methyl Ethyl Ketone (AKA M.E.K.) for cleaning oxidized aluminum parts. Just bought a 1992 Camaro 350 TPI engine that sat outside under a tarp. It has that white crusty oxidation on the aluminum fuel injection parts.
In the past I would scrub with a wire brush to get the parts cleaned up...which took a bunch of time/labor. Just bought a can of the MEK and put a little on the TPI plenum then used a small stainless wire brush to work it into the crusty surface. In very liitle time and effort the plenum cleaned up nicely..need a smaller brush to get into the grooves.
Attached a picture after the scrub..wish I would have taken a picture before I started. Really works great..BUT you need to do it in a well ventilated area :o

Ed your right ..The stuff does work great but according to some studies is potently very toxic. My guys in the body shop used to use it but OSHA rules proved tough to comply with. One thing for sure,wear a respirator even in a well ventilated area.
