Hi

I gave my wife some Castrol LM grease to put on the gears inside an old
(60s/70s) sewing machine. Unfortunately some of the gears are plastic.

The questin is, will the (presumably) petroleum based grease damage the
plastic?

If so, what's the best way to clean it off without further damaging the
plastic?

LM grease is a lythium based lubricant. I am no expert on this, but in
my experience, I can't see a problem.
