new tile, older pool---after the winter a layer of calcium buildup appeared along the water line--on the new tile.
the folks that installed the tile said "don't" use anything abrasive on the tile--so what can i use on a vertical surface, without abrasion, to remove calcium buildup?

You'll need to use a dilute acid to clean the tile. Muriatic acid, about a gallon should do it. Dilute the acid to 3 parts water one part acid in a small total volume.
Remember to always add acid to water, not vice versa.

Test to see if this is strong enough to takle the calcium. If not make it a bit stonger.

If the pool is full, it is preferable to drop the waterline so as not to dilute the acid further.

Don't allow the acid to stay too long on the tile, but don't panic. I think your test spot will show the grout will hold up. The acid will not damage ceramic pool tile. Use a sponge to apply just long enough.

Use gloves, goggles and have plently of water available (like a pool!).

( I opened about 50 commmericial pools each summer for about 15 years. Each one was acid cleaned each year and refilled.
