Ahhhhh, the ever popular, on going question. I have before me two cans of spray cleaners, one at $2.00 per can and the other at $8.00 per the same sized can. I read the contents of both cans and they are the same. The $2 stuff is "SUPER X" brake cleander and the $8 stuff is "CRUD CUTTER" a brand of gun cleaner. I buy 4 cans of brake cleaner and do a lot of firearms.
You can also spend a little more a can and buy automotive electronics spray cleaners. If they don't hurt computer parts, they will not hurt you favorite bullet blaster.
