Hot Tub Things® Cartridge Cleaner – Professional Filter Cleaning Solution
Hot Tub Things® Cartridge Cleaner is a concentrated filter cleaning solution specifically formulated for hot tub and spa cartridge filters. Unlike simple water rinses, this cleaner penetrates deep into the filter pleats to dissolve body oils, sunscreen, cosmetics, mineral deposits, and other contaminants that clog filter media and reduce water flow. Regular use keeps your filtration system operating at peak efficiency, ensuring crystal-clear water and optimal circulation.
