Hi All,

I did a Google search and found that a chemical called Methylene Chloride can be used to strip the green solder mask from circuit boards. Unfortunately, if left exposed for too long, it can also start to attack the metal underneath. Has anybody ever used this chemical and how well does it work?

I only looked at Hi Valley Chemicals, but they do list it at $42.25 for a 1 gallon bottle. Bad news is the shipping is $51.94 for that same gallon bottle.
