pool tile crud removal

I have a 38,000 gallon in ground plaster pool. Around the edge are four rows of tiles, about 1 1/2" square. They are a pretty blue, but have a lot of scale on them from hard water. It rubs off with a fingernail, so is not on there really hard.

What would you use to clean this with? I am reluctant to use a power washer because I don't want to blast the grout loose. I thought about draining the water down, spraying it with CLR, or LimeAway, or something like that, then scrubbing with steel wool or brushes.

Anyone got any suggestions? I want to do it right, and want it to look nice, but I also don't want to spend lots of man hours on it.

There is nothing better than a razor blade scraper. It goes really fast after a few minutes of 'learning' and does minimal damage.

What I've always used is a "block" of what looks like volcanic pumice rock that's specifically designed for this purpose. Your pool store will have it in various sizes. The block wears rapidly, and you have to vacuum up afterward, but it seems to work quite well on hard water deposits on tile without scratching it.

And of course diluted muriatic acid would also work, but you would have to be really careful, and over time might dissolve away some grout. DO NOT use CLR or Lime Away.

Whatever you do, I think you will have some hours of work involved.

Eau contraire, mon ami. I intend to hire ten topless maidens to do it while I supervise.

Ah, yes. The old "topless maiden" ploy. Well, have fun getting your tile polished.
