I have a sawstop with which I'm completely in love. Or at least as much as you can love a power tool. anyways, like many of us here, I'm coming off of Christmas projects and the mad dash to finish projects. Now that Christmas is over, there's a little time to breathe. My cast iron top is looking rough. it has some surface rust and even some scratches. what's the best way to get it back to "like new" condition? i don't mind seeing some of the scratches, but i don't want to feel them. i generally coat regularly with johnson's paste wax. but i want to do a deep clean and "lightly resurface" the top. what's the best way to go about doing this? bar keepers friend? naval jelly? wet sand with high grit wet dry paper?
