A swimming pool that is not properly cleaned and maintained well can be pretty unpleasant. Imagine dipping in the pool and seeing algae swarming the plaster surface. Even worse is when you cannot even see the bottom because the algae have grown too much under that not even chemicals can remove them.

I suggest you try acid wash. It has been proven to remove algae growths remarkably well. Just make sure that you handle these properly and that you have someone with you in case of emergency and spill. Remember that acids can be potentially corrosive, so take extra care in handling them.

Here are the most effective and safest ways to acid wash your pool:

  1. First, make sure to turn off the power of the pool’s filtration system and close the fill valve.


  1. Using a sump pump, drain the pool by putting the drain hose in the deepest part while it is connected to the sump pump. The other end must be connected to the drain-out valve.


  1. Wash away dirt from the pool by using a garden hose as the water level starts to drop. Start brushing the sides of the pool. Sweep away the dirt into piles and place them in garbage disposal bag.


  1. Wear protective gears, respirator, and gloves. Mix a gallon of water and a gallon of muriatic acid. Add the water first and then the acid. Always mix them in this fashion since doing it the other way around can cause bubbling which can spray onto you.


  1. While cleaning, focus on one side of the pool first. Make sure that the water is running while you are scrubbing the pool.


  1. Pour the acid solution slowly and with utmost care at one side of the pool. Then brush the plaster surface. Do not rinse that section for about 30 seconds.


  1. After 30 seconds, rinse the acid-scrubbed part of the pool thoroughly. Rinse properly until the pool is squeaky clean. If you are not satisfied and you can see there is still dirt in the surface, then repeat the process of pouring the acid solution, brushing, and letting it stand for 30 seconds again.


  1. Mix in two pounds of soda ash per gallon of acid solution. Stir it with the pool brush. This action neutralizes the acidity as evidenced by the cessation of bubbling and foaming.


  1. Then, put the sump pump in the deepest end of the pool and drain out the remaining water while continuously rinsing and draining.

Things to bear in mind when working with acid:

  1. Always wear protective gear, gloves, and respirator mask.
  2. If a spray of acid gets in contact with your skin, rinse it with running water for about 15 minutes.
  3. Always have someone with you when working with acid in case of emergency.
  4. Keep children and pets away from the area while working with acid.
  5. Wash out any acid sprays in your protective gear before removing them all.
