Keep your hot tub or pool running at peak performance with Spa Marvel Filter Cleaner—the most economical and user-friendly way to clean cartridge filters. Most filter cleaners rely on harsh chemicals, create excessive foam, and cost significantly more per use. Spa Marvel takes a smarter approach. With 8 full cleanings per bottle, you get powerful results at just $3.75 per cleaning, making it one of the most cost-effective solutions available. Its non-foaming formula ensures that even if small amounts remain after rinsing, it won’t interfere with your water chemistry or create unwanted foam—something many competing products struggle with. Designed to be tough on grime but gentle on filter fabric, it penetrates deep into cartridge pleats to remove oils, cosmetics, dirt, and buildup—helping your filter work more efficiently and last longer. ✔ Why Spa Marvel Stands Out: * Lower cost per cleaning * No foam or residue issues * No acids or bleach * Safer for filters and easier to use * Better long-term water clarity 🔹 How to Use 1. Remove filter and rinse debris 2. Mix 2 capfuls with up to 20L (5 gallons) of water 3. Soak filter (4 hours or overnight) 4. Rinse thoroughly with strong water pressure 5. Reinstall and enjoy cleaner water
