anyone got ideas on cleaning this ?

Hi george,

Gotta photo? That's something I've never encountered...

###

no photo's. working on that. but there seems to be stains, etc. the porcelain is smooth as glass but ya can see white dots and wavy stains. used oven cleaner and steel wool and scrubbed till i wore out. no change. not a real biggy but would like to start fresh after going to all the trouble of rebuilding the wsm. noticed something similar on the kettles but not as bad.

I've used automotive metal polish with really good luck.
