Remove Limescale Deposits From The Waterline Tiles In An Inground Pool

Posted on: 23 December 2015

Limescale deposits often form on the tiles that run across the waterline in an in-ground swimming pool. This can occur if the water is hard as a result of of chemicals that may have been added to the pool incorrectly. Learn how to remove these unsightly marks from the tiles in your pool with the following steps.

Materials

  • soft cushion
  • acidic gel tile cleaner
  • lint-free cloths
  • stiff-bristled scrub brush
  • plastic putty knife
  • sponge 
  • bucket of water

Lower The Water Level And Prepare The Work Area

Lower the water level inside of your pool so that it falls below the bottom row of tiles that runs across the waterline. You can clean the tiles while you are in the pool or from the side of the deck that surrounds the pool. If you decide to clean tiles from the deck, place a soft cushion on it so that you can kneel down and remain comfortable as you are working. Fill a bucket of water and place it near the edge of the deck.

Apply Acidic Gel Cleaner And Remove The Deposits

Pour a small amount of acidic gel cleaner onto a lint-free cloth. Move the cloth over each limescale deposit. Work in small sections at a time so that you can successfully remove all of the limescale deposits that are present in a particular section before moving to tiles that are further away. Wait several minutes for the gel to penetrate the deposits. Scrub the deposits with a stiff-bristled scrub brush to remove them.

If any deposits are thick and you are having difficulty removing them with the scrub brush, place the edge of a plastic putty knife underneath the edge of each one to loosen them. Pry the deposits from the tiles by lifting the handle of the tool away from them. 

Rinse The Tiles With Water And Dry Them

Once all of the limescale deposits have been eliminated, wipe the tiles off with a damp sponge to remove the gel. Rinse the sponge out in a bucket of water as it becomes covered with gel and continue moving along the length and width of the pool until all of the tiles are gel-free. Dry the tiles with a lint-free cloth when finished. Once the tiles are dry, you will be able to clearly see if all of the limescale deposits have been eliminated.

Have the water inside of your pool tested to determine if more chemicals need to be added to it. Add water to the pool until it is at the level that it was at before you cleaned the tiles. Contact a local swimming pool maintenance company for additional advice.
