All good advice above!

I use wet sandpaper laid on a piece of plate glass. The plate glass is wetted and placed on a few wet pages of old newspaper on a tile counter. 400 grit for start on 4K and 8K Norton; then 600grit for both. 600g and 1000g for the 15K Pro. Shapton followed by 1000g and 2500g. 3000g for the Shapton 30K glass. I like the ability to use the grits I know work for me. After a session, I keep the washed sandpaper standing in the sink to drain then insert them separately into an old issue of Shotgun News along with the plate glass. I store on tile with some flat weights (books).
