How to Make Homemade Spa Filter Cleaners

Updated February 21, 2017

Every two to four weeks, a spa filter should be removed from the filtration system and cleaned. Removing the dirt and debris from the filter allows it to continue effectively and efficiently filtering the water. If not properly cared for, the filter will lose efficiency and eventually stop filtering. Typically, spraying the filter with a hose will remove all dirt and build-up. However, if after spraying the filter you notice it is still dirty, soaking it can remove all remaining residues and oils. While homemade spa filter soaks are sold at most pool supply stores, vinegar or chlorine can be used to make your own homemade cleaner. Every six months, use a soak of muriatic acid for deep cleaning.

  1. Combine 3 cups of white vinegar with 4 litres of warm water in a bucket deep enough to submerge the spa filter.

  2. Submerge the spa filter in the water.

  3. Allow the filter to soak in the diluted vinegar overnight, or for about eight hours.

  4. Remove the filters from the water and use a hose to rinse away all remaining dirt and vinegar residue.

  5. Combine 1/4 cup of chlorine with 4 litres of warm water in a bucket deep enough to submerge the spa filter.

  6. Submerge the spa filter in the water.

  7. Allow the filter to soak in the chlorine over night, or for approximately eight hours.
