Protect Your Pool from Stains and Scale with Professional-Grade Treatments

Even a well-maintained pool can develop unsightly stains or stubborn scale buildup. Metals like iron, copper, and manganese can discolor pool surfaces, while calcium deposits leave rough, chalky buildup that damages plaster, tile, and equipment. These issues don’t just affect your pool’s appearance—they can also compromise water balance, reduce circulation efficiency, and shorten equipment lifespan.

That’s why pool owners and service professionals rely on stain and scale control products. At Benchmark Pool Supply, we stock a full range of stain removers, sequestering agents, and scale inhibitors from trusted brands. These treatments help prevent and remove staining and scale, keeping your pool surfaces smooth, clean, and inviting.

Protect surfaces further with Balancers, pair treatments with Specialty Chemicals, and improve clarity with Clarifiers.

Why Use Stain & Scale Products?

  • Protect Pool Surfaces – Prevent discoloration on plaster, tile, vinyl, and fiberglass.

  • Maintain Smooth Walls & Floors – Stop rough calcium deposits from forming.

  • Safeguard Equipment – Protect heaters, filters, and pumps from scale buildup.

  • Improve Water Balance – Support consistent pH and calcium hardness levels.

  • Enhance Appearance – Keep water sparkling and surfaces stain-free.

Types of Stain & Scale Products

1. Stain Removers

  • Remove iron, copper, and organic stains from pool surfaces.

  • Often formulated as spot treatments for tough discoloration.

2. Sequestering Agents

  • Bind metals in the water to prevent them from depositing on surfaces.

  • Used as a preventative treatment after filling or shocking pools.

3. Scale Inhibitors

  • Prevent calcium and mineral scale from forming on surfaces and equipment.

  • Essential for hard water areas.

4. Combination Formulas

  • Treat both stains and scale in one convenient solution.

  • Ideal for routine maintenance.

5. Specialty Treatments

  • Products tailored for plaster pools, vinyl liners, or saltwater systems.

  • Offer targeted protection for unique pool types.

Signs of Stains & Scale in Pools

  • Brown or Rust-Colored Spots – Usually from iron.

  • Green or Blue Stains – Often linked to copper.

  • Black or Purple Streaks – Manganese deposits.

  • White, Rough Buildup – Calcium scale forming on tile or plaster.

  • Cloudy Water & Poor Circulation – Caused by clogged equipment from scale.

Maintenance Tips to Prevent Stains & Scale

  • Test water weekly for pH, alkalinity, calcium hardness, and metals.

  • Use sequestering agents when filling or refilling your pool.

  • Shock pools carefully—oxidizing metals can cause stains.

  • Maintain calcium hardness between 200–400 ppm.

  • Brush tile lines and surfaces regularly to reduce deposits.

  • Treat early—once scale hardens, it’s much harder to remove.

✅ FAQ – Stain & Scale Products

Q: How often should I use a scale inhibitor?
A: In hard water regions, add weekly or monthly as recommended by the manufacturer.

Q: Can stain removers damage pool finishes?
A: When used properly, stain removers are safe for plaster, vinyl, fiberglass, and tile. Always follow instructions carefully.

Q: What’s the difference between a stain remover and a sequestering agent?
A: Stain removers treat existing stains, while sequestering agents prevent metals from causing new stains.

Q: Do I need stain and scale products if I have a saltwater pool?
A: Yes. Saltwater pools can still experience stains and calcium scaling. Specialty formulas are available for salt systems.

Q: Can I swim after using stain and scale products?
A: Many products are safe to swim in shortly after treatment, but always check the product label for wait times.

Q: What causes recurring stains even after treatment?
A: Persistent stains often indicate a source of metals in the water supply. Using a sequestering agent regularly can help.
