Just cleaned a swimming pool that had a major mineral buildup on the tile along the top. The pool was empty, and the owner had tried several ways to remove the white crud, but nothing worked.
I used a sand blast attachment on my wand, and shot glass beads instead of sand. The white stains disappeared! I was impressed, as I had not expected such ease and success. Be sure to wear good eye protection, and watch your footing, as the beads act like ball bearings underfoot.
The homeowner will be doing the chore of cleaning up all the junk at the bottom of the pool, but he's happy not to be scraping tile...
