I use a fair bit of acetone. I have always accepted that it leaves a

so is the likely cause cutting costs during production?

Acetone evaporates almost instantly, and leaves *no* residue. If you're
seeing any oily residue at all from acetone, it's not pure. Bitch at the
supplier.

What specific product are you using, so I know what to avoid? :-)

This can came from HD. It is not a problem really as I have been using
a two-stage procedure for degreasing for some time now (that is if I
need a *really* clean item - has to pass a waterbreak test).

It's just that the amount of grease in this last can was more than I
remember previously.

BTW I find proper degreasing another one of those Black Magic
procedures: You have to do it right before the next process, you
cannot do it a day in advance. You also cannot do Stage 1 one day and
the Stage 2 the next day. Why? Lord knows...
