Well, now that my stove is out of the basement and i can get to all of it, i would like to replace the gaskets, and especially the gasket on the glass. However there are two screws 1 on each side that hold brackets that hold the glass in place, and they are stuck. Plus it would look as if someone tried once before because the screws look a bit "worn" . should i soak them with PB Blaster or something else to see if they free up? What do you guys do to get these out (without drilling and tapping)
