Protect Your Pool Surfaces from Unsightly Stains – Remove & Prevent Metal Buildup Fast
Iron, copper, and manganese stains can ruin the look of your pool and damage expensive surfaces over time. Applied Biochemists Staintrine is a professional-grade stain preventer and remover that targets the source of pool staining—metal deposits in your water—and eliminates them before they settle or oxidize.

Staintrine’s advanced sequestering formula works in both fresh fill water and existing pools to neutralize dissolved metals, helping to clear up discoloration and prevent long-term staining on vinyl, fiberglass, plaster, and painted surfaces. Safe, easy to use, and compatible with all pool sanitizers, it’s a must-have for pools on well water or those prone to scale and staining.
