I have an enamel stove. Lucky me, I had some boil over. Tried everything to clean the stove without scratching the enamel. Tried Oxy clean, vinegar, etc.
Final solution was Mothers Body Clay.
Mothers® California Gold® Clay Bar System
I use it to get boot marks off of my motorcycle pipes, remove nasty stuff from the car finish, etc. Works great, doesn't scratch your finish (but requires a lot of elbow greese)
Anybody have any other suggestions?
