Is it safe to use WD40 as a switch (or potentiometer) cleaner on
circuit boards and in electronic equipment?

I have used WD40 to clean residue of silicone sealant from acrylic shower
tub in my bathroom!
Spray it on, wait 30 seconds and clean it with wooden spatula or
figernails
and paper towel.
Repeat on thicker patches.
Kind regards!

Another thin that WD is good for is removing tape and label adhesive
residue. I don't know why, but it works almost as well as stuff actually
made for the purpose.
