Bio-Dex BD300 – 300 Tile Cleaner (Pool & Spa Tile Scale Remover)
The Bio-Dex BD300 (300 Tile Cleaner) is a professional-strength tile and scale remover designed for pool and spa tile, coping, and other non-porous surfaces. It dissolves calcium deposits, scale, oil, and mineral build-up — helping restore tile shine and improve overall waterline appearance.
Key Features
- Strong chemical formula that breaks down calcium scale, mineral deposits, grease, and grime.
- Effective on pool/spa tile, waterlines, coping, and other non-porous surfaces where scale accumulates.
- Works on stubborn deposits that standard tile cleaners cannot remove.
Specifications
- Brand: Bio-Dex
- Part Number: BD300
- Form: Liquid cleaner
- Intended Use: Removing calcium scale, mineral/metal stains, oil films, and heavy buildup from pool tile and non-porous surfaces
When to Use / Replace
Use BD300 when tile or pool waterline surfaces show scale buildup, mineral staining, or persistent deposits that don’t respond to routine cleaning. It’s ideal for deep cleaning before repainting, resurfacing, or seasonal start-ups to restore tile appearance and surface cleanliness.
Application & Safety Recommendations
- Wear protective gloves and eye protection — this is a strong cleaner, not a mild detergent.
- Apply to dry surfaces only — on tile, coping, or non-porous areas needing cleaning. Avoid applying directly onto pool plaster, grout, or porous surfaces.
- Work in small sections and monitor dwell time — surface sensitivity varies by tile type and age.
- After the cleaner has worked, scrub if needed and rinse thoroughly with fresh water to remove residual chemicals before refilling the pool or allowing swimmers.
- Do a test patch in an inconspicuous area before widespread use to ensure compatibility with your tile or coping.
