i fixed my pinking shears with pb blaster (auto dept in wally world), let them sit for a couple of hours and then cut up every rag i could find, the stuff is greasy, and wiped them down really well, it took some time to loosen them up and get all the smelly pb off them, but it worked. and the nasty stuff will help with tools too. (had to hide mine from bob, bf, as he keep thinking it was his, he has his own, lol) but i have also used it to get adhesive off stuff. it will take the finish off paint, so if you have any be careful. silicone spray will also help. (i do upholstery on boats, that is why i have some really wierd things under the cabinet.
happy quilting
