How to Remove Calcification From Pool Tile

Calcification occurs when there is a buildup of calcium deposits. If you have calcification on your pool tiles, you'll notice white residue on the surface. It can be especially noticeable if you have a darkly colored tile. Remove the calcification yourself by using certain pool-cleaning materials. If this proves unsuccessful, hire a professional pool cleaner to perform the job. He can use a method that involves blasting with glass beading to remove the calcium deposits.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Paintbrush
• Pool pH test kit
• Pool tile cleaner
• Gloves
• Eye protection

1. Put on gloves and eye protection when planning to get rid of calcification on your swimming pool tiles. The chemicals you will be handling can be very harsh.

2. Conduct a water analysis with a pool test kit to determine the pH level of your pool. If the water is out of range, it can cause deposits to build up. Ideally you want the level to be at 7.2. If it is too low, use a substance like sodium carbonate. For a pH level that's too high, add muriatic acid. Follow the recommendations provided by the manufacturer for dosing.

3. Use a swimming pool tile cleaner. As an example, you can purchase Scale B Gone through an online cleaning supply company like Always Brilliant. The cleaner is available in gel form and should be squirted onto the areas of your pool tile that have calcification. Spread the pool tile cleaner using a paintbrush to make sure you get as much of the tile covered as possible.

4. Wait several minutes and then rinse off the residue with clean water. If the calcification returns, you may need to reapply the cleaner.

Tips & Warnings

• As an alternative, you can use muriatic acid diluted with water to clean the calcium deposits. Apply the chemical to the tile with a sponge and rinse the residue away with clean water.
