Now now now, don't go get worried, I am talking about stripping off paint on old door hardware!
We are replacing the door on the bathroom and I remember seeing something about stripping old paint off metal hardware...in the crock pot. Sounds simplet, no nasty paint stripper, no hard scrubbing. I was game. I took the back plates and knobs off the bathroom door, and put them in the crock pot with a bit of dish soap, turned it on high and waited about 24 hours.
Now, they are not fancy, they are just steal and plain, but with a good spray down with some spray paint, they will be set for a new life on the new bathroom door.
