I'm using a HD degreaser made by ZEP, either the same or very similar to Industrial Purple, to degrease parts. I've noticed that it will occasionally react with certain types of aluminum, making the part either white (hard crystal -like areas) or sometimes black. I totally submerse the parts, and leave them anywhere from 1 hour to a day or more.
Do I need to cut the cleaner with water, or isn't it a problem?
Today it soaked some sportbike parts and the cast brake and shifter turned dark grey/black in spots. The top triple clamp was not affected.
Most of it will be blasted anyway, but on things like the underside of a VC it needs to be scrubbed-off (mostly the white, crystal-like residue) to look decent.
What do most of you use for degreasing? Do you completely submerge the parts? How long?
Thanks.
