I'm thinking of embedding a circuit into a jacket that I have, and I was wondering whether I could dry clean it with the circuit still attached to it. I read that dry cleaning could potentially dissolve items like plastic pens and was wondering if it could dissolve the PCB or the chip's shell...

PWB is an epoxy resin fiberglass mix and plastic chips are encased in an epoxy resin polymer mix both similar to epoxy adhesive which are category 4 = not recommended with Perchloroethylene , the dry cleaning fluid commonly used. Perhaps something else can be used. http://www.beaconadhesives.com/epxchmresis.html

I use acetone, trichloroethylene and perchloroethene to clean prototype boards from solder remains. Often the liquid goes on chips and components, and in 20 years I never had a single problem with components or PCB itself.
