You can clean your swimming pool or hot tub spa's cartridge filter element with either a degreaser or acid bath, or per the manufacturer's specifications. For more information on cleaning your cartridge filter element, read below!
A degreasing solution removes all the body oils that will clog cartridge elements. Acid baths can sometimes imbed the oils into the cartridge filter material and make it less effective over time. You can purchase a cartridge cleaning solution, or you can make one yourself with a mixture of laundry detergent and water! When mixing it you should use about one cup of detergent for five gallons of water. Once mixed, let the cartridge soak in the mixture overnight. Be sure that you thoroughly wash the cartridge before reinstalling it into the filter so that you don't have soap bubbles that appear.
We recommend an acid bath only when you have mineral deposits that are built up on the cartridge. Whenever you need to use an acid bath on your cartridge, make sure that you use a degreaser wash first. To begin, you will need to mix 1 part acid to 5 parts water in a medium sized bucket. *Be sure that you add the water to the bucket before adding the acid!* We also recommend that you follow the acid manufacturer's guidelines for using their product, and for the proper disposal of the acid mixture once you are done.
If your cartridge filter is showing signs of wear and tear or distress and it is not filtering properly even after cleaning, it may be time for you to consider buying a replacement cartridge filter element.
