Frequently Asked Questions

Q: Do I need to use Poolife™ Stain Lift before using Stain Stop?
A: Yes — Stain Stop is designed to maintain and protect after stain removal. Always start with Poolife™ Stain Lift for visible stains.

Q: What happens if I don’t use Stain Stop after removing stains?
A: Without ongoing protection, metals in the water may cause new stains to reappear, especially in warm temperatures or unbalanced water.

Q: Can I use this with my saltwater system?
A: Absolutely. Stain Stop is compatible with saltwater, chlorine and bromine systems — just not with biguanide-based sanitizers.

Q: How quickly does it work?
A: The protective effects begin immediately upon circulation and are most noticeable with regular weekly use.

Q: Can I use Stain Stop as a preventative even if I’ve never had stains?
A: Absolutely. Stain Stop is an excellent weekly preventative solution, especially if your water contains metals or minerals that can cause future stains or scale buildup.

Q: Will this product affect my pool’s chlorine levels or pH?
A: No, when used as directed, Poolife™ Stain Stop will not significantly impact chlorine levels or pH. Always test and maintain proper water balance.

Q: Can I use this product if I’m also using phosphate removers or clarifiers?
A: Yes, but it’s best to wait 24–48 hours between treatments to allow each product to work effectively. Always follow label directions for each chemical.

Q: What’s the difference between Poolife™ Intensive Stain Prevention™ and Stain Stop?
A: Both prevent staining, but Stain Stop is designed as a follow-up to Poolife™ Stain Lift and used weekly to maintain stain-free surfaces. Intensive Stain Prevention™ is ideal for broad, ongoing scale and stain defense, especially at pool startup.
