The tile around a swimming pool

[adamh]

Hoiday inn would like the tile cleaned around their inside pool. The tile is man made and very dirty. I ran some tests with everything I have. Nothing would touch it. Not even 2500 PSI and a pressure washing lance.

Any ideas?

The best results I've had was muriatic acid, doing a google on this, some have used a spray bottle and protective gear of course.

Epson salt blasting media seems to work well and doesn't need the pool drained. A buddy of mine has a set up a does a few dozen pools every year this way.

go to pool supply store, they have what you need.

Muriatic even has a hard time with that build up. It will also throw the water out of balance. Bead blasting, or dry ice blasting are the best. Dry ice is more expensive to begin with but equals out due to the labor to vac the pool to recover the beads. Neither process will mess up the water balance.
