Need a little help with my pool tiles. These are the ones on the pool
lip. They were originally light blue and had turned blackish with what
looked like baked-on hard soot or grime. I've tried most of the tile
cleaners and they were not effective.
Pumice seemed to do the job, however it was slow going and hard to get
into the crevices (the tiles are "dimpled" to avoid slipping). What
are my other chemical alternatives? Would muriatic acid do the job?

on top of it before.
What you may have here is dirt attached to your tiles by stearates.
Many chlorinator tablets, particularly the three inch diameter ones
employ a metalic-stearate binder to keep them in tablet form like
sodium, potassium or calcium stearate. These esters of stearic acid are
soapy materials which are relatively insoluble in polar solvents like
water. They accumulates near the surface where they carry surface borne
dirt and dust to the tiles at the edge of the pool.
You may be able to remove it from the tile with a non-polar solvent like
kerosene, or any other solvent that would dissolve greases or soaps.
The longer term solution is to get away from this method of
chlorinating. Many of the 1" chlorinator tablets do not use stearate
