BioGuard Kleen It Filter Cleaner - 1 Quart

BioGuard Kleen It Filter Cleaner is a pool filter cleaning solution designed to remove metals, dirt, scale, and buildup from sand, D.E., and cartridge filters. By helping your filter work more efficiently, Kleen It supports better water clarity, longer filter cycles, and easier pool maintenance throughout the season.

Deep Cleaning for Better Pool Filtration

A dirty pool filter can reduce circulation, shorten filter cycles, and make it harder to keep pool water clean and clear. BioGuard Kleen It helps remove the buildup that can collect inside your filter over time, including scale, metal deposits, dirt, debris, and clarifier residue.

This 1 quart filter cleaner can be used as a spray or soak treatment for cartridge and non-backwashable D.E. filter elements, or as a skimmer-applied cleaner for sand filters and some D.E. filters. It is a practical seasonal maintenance product for pool owners who want cleaner filtration and more reliable pool water quality.
