Without wishing to upstage PWB, here are a few good places to start. All glass windows and sliding doors, any glass, should have a little super-thin dime size Cream Electret rubbed on, same with all steel and wood objects, including chassis of electronics, wood panels of speakers, bookshelves, books, records, lamp cords, all power cords including TV, etc. some good places for silver rainbow foils - all book BARCODES, CD jewel case barcodes, any and all barcodes, one foil on the refrigerator, one on stove. The foils can be cut 1/8” wide each. So that’s enough to treat a lot of things.
