Hard water Foam Cleaner | 500ml x2

Hard water stains form when mineral-rich water evaporates and leaves calcium and magnesium deposits behind.

Over time these harden into thick limescale that bonds tightly to bathroom surfaces and becomes increasingly difficult to remove. Standard liquid cleaners run off vertical surfaces too quickly to break down thick limescale effectively.

Invisel Hard Water Foam Cleaner solves this with foam. The foam clings to any surface vertical tiles, glass, chrome fittings, and curved basin walls holding the enzyme formula in direct contact with the limescale for over a minute. During this time the formula actively softens and dissolves mineral deposits, making them easy to scrub off with light effort.

The result is a clean, residue-free surface without harsh chemical fumes or aggressive scrubbing. India has one of the widest ranges of water hardness across cities, which means the age and thickness of limescale varies significantly from home to home.

Old or heavily built-up stains may need 2 to 5 rounds to fully remove each round lifts one layer of the deposit.

Step 1 - Shake the bottle well

Shake before each use to ensure the foam formula is fully mixed.

Step 2 - Spray foam evenly onto the stained surface

Hold the bottle 10 to 15 cm from the surface. Spray the foam to cover the stained area completely tiles, glass, fittings, or grout. Make sure the foam is in full contact with the stain.

Step 3 - Leave for a minimum of 1 minute

Leave the foam undisturbed for at least 1 minute. For moderate stains, 2 to 3 minutes is better. The enzyme formula is dissolving the limescale during this time. Do not wipe early.

Step 4 - Scrub with a brush or non-abrasive pad

Use a scrubber brush or non-abrasive scrubbing pad to work the loosened scale off the surface. The limescale should come off with light to moderate effort after the foam has had time to work.

Step 5 - Rinse thoroughly with water

Rinse the surface thoroughly with clean water until all foam and residue is fully removed. Wipe dry with a clean cloth for a streak-free finish.

Step 6 - Repeat for old or heavy stains

• Do not use on natural marble, granite, limestone, or any unsealed natural stone surface the acid formula may etch or damage the surface.
• Do not use on aluminium fittings or anodised surfaces without patch testing first.
• Avoid contact with eyes. If contact occurs, rinse immediately with large amounts of water for 15 minutes and consult a physician if irritation persists.
• Use in a well-ventilated area. Open windows and switch on exhaust fans during application.
• Do not mix with bleach or any other cleaning product. Mixing with bleach can release hazardous fumes.
