- REMOVES IRON STAINS FAST: Dissolves ugly brown iron and rust stains from pool walls, floors, and hot tub surfaces in as little as one treatment. No scrubbing, no draining — just dose and watch stains lift.
- 100% NATURAL, ZERO HARSH CHEMICALS: Made from pure, Non-GMO ascorbic acid and plant-based ingredients. No bleach, no acid washes, no artificial additives. Safe for your family, pets, and pool equipment.
- WORKS OUT CHEAPER THAN PROS: One 32 oz package treats multiple stain events — far less than a $200+ professional acid wash or replacing a stained liner. Keep a bag on hand all season for pennies per treatment.
- DEAD SIMPLE TO USE: Sprinkle powder directly on the stained surface at the recommended dose. Once the stain lifts (often within hours), follow up with a standard metal sequestrant to clear dissolved iron from the water. No special tools needed.
- MADE BY MINERAL POOL EXPERTS: From Think Minerals, the makers of ClearBlue Ionizer systems trusted by thousands of pool and hot tub owners. We know pool chemistry inside and out — this formula is designed specifically for pools and hot tubs
