How do you get rid of calcium depositis on pool tile?

Answer 1

I'm guessing that you have a salt water pool. Sometimes water will evaporate and leave behind salt crystals. Usually the problem is calcium or other hard water minerals that get deposited at the water line and anywhere water splashes on the tile. If you do have "salt" it will probably just brush off. If however it is calcium it can be removed with an acid (like Biodex 300) while it is just a light film. If it has accumulated enough to form a crust you will most likely need a professional. There are three methods to remove it. Some use wire wheels and grinders others use sand or glass bead blasting. The newest method, and least damaging to tile is water blasting with magnesium sulfate.

Answer 2

Are you sure it's chlorine? If so it should rinse off with water. If on the other hand you are talking about a white film or deposit at the water line it is most likely calcium or another hard water deposit. A film can usually be removed with an acid product (I prefer Bio Dex 300) be very careful to follow the instructions, it is very dangerous. If calcium is allowed to build up too long it forms a thick crust almost impossible to get rid of. You may try a pumice stone (follow instr or you can damage the tile. Failing that you'll need to call a professional. One process uses glass beads to blast the residue off. The newest process uses high pressure water and a soft media to remove the calcium ******************************************************************** People using acid need to be very careful as to you can easily ruin more than just your tile. As far a glass beads goes you would be better off getting a piece of coarse grit sand paper and scuff away because you'd get the same result of having someone bead blast it; but on more of the harder surfaces like fake rock, stone, flagstone, etc glass beads would work well. But the water blast setup works by far awesome. Maxxstrip is the media in term "soft abrasive" that would be used it safely removes build-up on tile and even leaves a shine to tile.

A lot of people will use a scouring pad with a strong detergent. this is not necisarily good for the chemical composition of pool water. it is wisest to seek advice on this from your local pool shop as they will carry exactly what you need.

Answer 4

You can DIY if it is still just a light film. I use a product called Bio Dex 300 FOLLOW the instructions or you could damage the tile or worse, hurt yourself. If the deposit has gotten to the thick baked on stage you probably need a professional. The old method uses air blasting and glass beads. A newer method only available in the past 4 years uses a power washer and a mineral salt to clean. Do your homework before hiring someone.

Depending on how many hard water stains there are on the pool, you could try a natural method. White vinegar has been proven to work time and again and is non-toxic, see below for a proven step-by-step technique:

Natural Formula to Use:

A mixture of baking soda & white vinegar to make a paste

Method to Use:

1. Make up the mixture of water and baking soda

2. Apply to stain and let dry on the tile

3. Scrub stains with a brush or sponge

4. Rinse thoroughly with water to remove all residue, reapply if necessary

Answer 5

You didn't say what you are trying to remove. If you have mold, algae you could try using biodex 300, (or a similar prodict) a very strong acid. BE CAREFUL. If it's a mineral deposit (usually calcium) Biodex will also work as long as the deposit is just a film. If it's been around awhile and is thicker you can try a pumice. Be careful not to scratch the tiles. If it's worse you will need to hire a professional. There are basically three methods that work. They may use a grinder or sander to remove the deposit (easily damages the tile) they may use glass bead blasting ( also easily damages tile) The newest method is to use a power washer and mineral salts. (won't damage tiles) The mineral used is too soft to damage the glaze. Despite claims from bead blasters it won't knock the tiles off either. If the tiles are loose enough to fall off you have a more serious problem.

Answer 6

Chlorine residue? Chlorine is a gas that dissipates automatically over the course of many hours - that's why you have to add it every day. There is no "residue". To reduce the chlorine content of pool water, merely wait 24 hours - 48 if neccesary.

Answer 7

Try CLR ( calcium lime rust ) remover, it is available at most supermarkets and home improvement stores.

Answer 8

The only way I would sugest to do this is to bead blast it away by calling Surface Renewal (949)269-3122
