Hi, what grinding tool do you use? 

Especially for bigger surfaces like flat bottoms (no foot) or just kiln shelves.

I searched through discussions. People use Dremel tools but I think it is just for foots or details covered with glaze.

You might take a look at these tools from Harbor Freight. I've used something similar for grinding glaze off shelves, but it has to be done with a light touch or you'll wind up grinding grooves into the shelves. The price is right for what you want to do. My grinder is a Makita that I used to use in my remodeling business.

Good luck...

I use a 4 INCH MAKITA for grinding shelves with a masonry wheel-I also use a diamond wheel on tough shelves (not cordialite or mullite) 

for glaze runs on pots its a 8 inch bench grinder with a green silicon grinding stone then few small green grinding stones on two Dremel tools.I also use diamond bits as wheel

For rubbing pot bottoms smooth it's a  diamond  pad 100 mesh from tool city or a glaze eraser from Smith Sharpe

For shelves I usually start with hand tools -- cold chisel/hammer/silicon carbide rub-brick.  

Bad drips that eat into furniture I use a 4" angle grinder with a diamond-core grinder head -- I used to use a silicon carbide masonry head but the diamond-core head works amazingly well in comparison.

duck barn, could you please explain what you mean by "soap wash" your shelves?  do you mean that you actually get them wet and use soap on them?  may i ask why and how often you do this?
