Product Details

Apply undiluted directly to affected tile and grout surfaces; 1 QT. covers approximately 100-150 linear feet of waterline tile depending on scale severity.

- Safe for fiberglass gelcoat and sealed natural stone
- Not recommended for polished marble or acid-sensitive unsealed limestone
When To Use This
Pro Tip
Lower the water level 3 to 4 inches below the scale line before application. Acid-based cleaners work twice as fast when applied to dry calcium rather than submerged or water-diluted deposits.
Common Questions & Instructions
How do you apply Bio-Dex 300 Tile Cleaner to waterline scale?
Lower the pool water line a few inches below the scale mark. Apply Bio-Dex 300 directly to the dry scale using an acid-resistant brush or sponge, let it sit for 1 to 2 minutes, scrub lightly with a nylon pad, and rinse thoroughly with pool water.
Will Bio-Dex 300 Tile Cleaner damage pool tile or grout?
No, Bio-Dex 300 is formulated to dissolve mineral buildup without etching glazed ceramic tile or degrading sound grout lines when rinsed as directed. Avoid prolonged dwell times on unsealed concrete.
What personal protective equipment is required when using this cleaner?
Bio-Dex 300 is a professional-strength acid cleaner that carries a DANGER label for severe skin and eye burns. Always wear chemical-resistant gloves, eye goggles, and protective clothing during handling.
