Cleaning The Chlorinator Cell

The cell on your chlorinator is the most vital part of your equipment, it maintains the level of chlorine in the water so the pool doesn't go green. As a part of the process, the chlorinator will slowly become coated in a white-colored substance, that is calcium. While it is coated in calcium it can't do its job efficiently. Although many modern chlorinators are self-cleaning you will find that you still need to manually clean them from time to time. 


  • First make sure that the equipment is off, then if your pool is below water level shut off the valves leading in and out of the equipment.

  • Then prepare a solution of 1 part hydrochloric acid to 10 parts water in a plastic,  container/bucket. Always add the acid to the water, never the other way around. Remove the cell from its housing and place it in the solution making sure that the cables remain clear, it will start to fiz.

  • In 10 to 20 minutes it should be clean, if there is some build-up remaining try gently removing it with something plastic or wooden, NOT metal.

  • Place back in the housing, turn valves back on and return the system to its normal state of operation.
