What the AI looks for in Swimming Pool Stain Removers
- Identify the stain
- Organic stains (brown, green from leaves) lighten with chlorine. Metal stains (rust-brown for iron, blue-green for copper) respond to ascorbic or citric acid tests. Using a metal remover on an organic stain does nothing, and the reverse is also true.
- Sequestrant follow-up
- After lifting metal stains, add a sequestrant and find the metal source Stains return if dissolved metals remain.
- Water balance during treatment
- Follow label instructions on lowering chlorine and adjusting pH Many stain treatments are consumed or ineffective at high chlorine.
- Surface compatibility
- Check the product is approved for your surface (vinyl, plaster, fiberglass) Acidic treatments can damage some finishes.
