Hard-water stains on pool tiles are those cloudy-white residue that are caused by huge amounts of minerals present in the water like magnesium and calcium limestone. As water evaporates, these mineral deposits eventually form on the tiles. Good thing that these can be removed. There are many people who opt to drain their people just to remove stains, however, the cost, as well as the potential damage it can cause can be a trouble and this is something you don’t want to happen. You can only do this as your last resort. What you can do instead are the following.
Steps to Remove Hard Water Stains
- Prepare a container of muriatic acid but be sure to move it outside so it gets proper ventilation. Make sure that you wear rubber gloves and cover your eyes with goggles and a respirator before you open the container.
- Prepare a plastic bucket and fill it with a gallon of water. Get a measuring cup and pour 8 ounces of muriatic into the water. Don’t forget to put a label “muriatic acid only” so you can use it for your swimming pool in the future.
- Slowly stir the mixture of water and acid with a piece of wood or a plastic spoon. Never mix them too quickly as heat will be produce and it will start to boil. After stirring, dispose of properly the spoon or wood you used.
- Fill your spray bottle with water and muriatic acid mixture. Label the bottle and dispose of it properly.
- Start spraying the mixture to the pool tiles. Make use of a non-abrasive scouring pad when removing the hard stains. Never attempt to clean the tiles from the inside of the pool. In spite of using muriatic acid in the water of your pool to help maintain the balance of chemicals, remember that you are still dealing with a diluted kind of acid.
- If you have unused water and muriatic acid mixture, make sure that you dispose them properly. If you do not know how, you can contact the local municipality and ask them how to properly do it. Also, you can get in touch with your pool supply company as they are more familiar with the regulations of the municipality.
- Get a sample of the water in your pool and bring it to the pool supply company. This should be tested in order to determine hard water levels in the pool. They would be able to recommend the chemicals that you can use so you can avoid hard-water stains in the years to come, especially that hardness level can be different from one place to another.
By simply following these tips, you will be able to protect your tiles and your pool in general so you can enjoy it for longer years.
