Homemade Cleaners for Soaking Pool Filter Cartridges

After removing your pool filter cartridge from the pool filter and rinsing away all grime and residue, you may notice it is not fully clean. Body oils and suntan lotions can adhere to the cartridge and simply spraying the filter with the hose doesn't remove them. Although you can purchase cartridge soaks at pool supply stores, you can make soaks at home for a fraction of the price.
