"Do not use solvents on electronic equipment"

Not true. Chlorinated solvents, yes, but alcohol, a resounding no!

If your PCB maker is using a component silk screen ink that solves in alcohol, I would question a lot about the quality of other aspects of his manufactured product as well.

All of the inks I have EVER heard of were all enamels that were hardy to weak solvents like alcohol. It is actually a UL requirement IIRC. Same holds true for the makers of heat shrink wrapped and labeled parts like EL caps and the like.

A PCB is ALREADY hygroscopic unless it has been conformally coated.

An effective goo remover is peanut butter (aka peanut paste). In the absence of peanut butter, use WD-40. Both leave a smudge of oil, but that's easily cleaned up with a drop of detergent on a damp tissue.

On a metal or glass surface, tea tree oil and mineral turps are both good at removing sticker goo, but these can attack paint and plastics so don't use on such surfaces unless you are willing to accept some surface spoilage.

Also, bought in store tube of "RTV" The acronym means "Room Temperature Vulcanization". It isn't rubber, and there is no heat or sulfur involved.

It appears that it firms up rubber, and makes it stronger and better, but it seems to "firm up" plastics, and make them brittle or even cause micro-fractures in their molecular lattices.

I am sure the chemistry group boys could explain it a lot better than a lay person such as I as it relates to plastics and their interactions with various solvents. If they are even reading the thread.

Peanut butter? Heh! Now that will give me an excuse to keep a jar of peanut butter in the house.

Must try the peanut butter because although I haven't tried the tea tree oil you suggest for removing sticker glue, I have tried eucalyptus oil and it works rather well. Presumably eucalyptus oil is quite similar to tea tree oil in this respect.

Now here's another: if you are a sweaty sort of person then I find that skin oil (say, from the brow) works remarkably well!
