Which hard water stain remover should I choose?

Start by identifying the surface, any coating, and the type of stain. These options differ in formulation; a product that suits one job may not suit another.

• Bio Clean: A thick paste for water and mineral stains. It uses a mild abrasive, so avoid surfaces that abrasives can damage.
• Titan Labs A-1: A non-acid stain remover containing an engineered abrasive. Non-acid does not mean non-abrasive; check the surface requirements before choosing it.
• abc Water Stain Remover: A thick cream combining a mild acid with an abrasive for deposit buildup. The product is labeled for industrial and institutional use and for surfaces not harmed by mild abrasives.
• One Restore: A strong acid. Use gloves and goggles. Can't be used on the tin side of glass.
• Crystal Clear 550: The strongest option available for restoring severely stained windows. Use gloves and goggles. Can't be used on the tin side of glass.

Can I use these products on any window or shower door?

Do not assume every glass surface accepts the same cleaner or pad. Check the glass manufacturer's care instructions, especially for coated or treated glass, and the cleaner's label. Confirm compatibility with nearby frames, seals, and finishes too. Test a small, inconspicuous area before treating the full surface.

What should I check before ordering?

• The surface and finish you need to clean.
• Whether the product contains an abrasive or acid.
• The applicator, protective equipment, and rinsing steps specified on the label.
• The container size and quantity needed for your work.

Choose the pad or applicator specified for both the cleaner and the surface. A more aggressive pad is not automatically a better match. Follow the product instructions instead of applying one cleaner's method to another.
