Lithofin KF Bathroom Cleaner
Art. 306-21-B
Your bathroom tiles look dull, chrome taps show water marks, and stone shelves collect soap residue every day. Universal Badreiniger cuts through those calcium-rich deposits in minutes, letting you reset the whole room without harsh scrubbing.
What Universal Badreiniger Does
Universal Badreiniger is a mildly alkaline cleaner for bathroom stone, ceramic, glass, enamel, and metal fixtures. At pH 9.5 it breaks the bond between fatty soap scum, light limescale, and surface tension so dirt lifts on contact. Non-aggressive surfactants suspend the loosened grime until you wipe it away, leaving no film and no need for neutralising rinses on most substrates.
When to Use
- Polished vanity tops in marble: ready-to-use 1:0 for daily wipe-down.
- Rough shower floors in granite: ready-to-use 1:0 after each shower.
- Wall cladding in ceramic tiles: ready-to-use 1:0 twice weekly.
- Glazed porcelain sinks showing toothpaste haze: ready-to-use 1:0 on demand.
- Daily-maintenance touch-ups: ready-to-use 1:0, then follow the guide at daily maintenance.
How to Apply
- Hold the trigger 15 cm from the surface and spray a uniform film (≈10 ml/m²).
- Wait 60-120 seconds for the alkaline agents to loosen residues.
- Wipe with a damp microfiber cloth or sponge, applying light pressure.
- Rinse with clear water on food-contact or high-polish stone; towel-dry fixtures for streak-free shine.
One 500 ml bottle covers 50 m²; a full litre cleans 100 m². The surface is dry immediately; no curing time.
Surface Compatibility
The formula is safe on acid-sensitive stones because its pH stays below the etch threshold while remaining strong enough to cut bath grime. You can use it confidently on slate, basalt, granite, porcelain, and ceramic tiles. It also works on medium-porosity stones such as marble and limestone-test first. Do not use on freshly waxed cotto or other coatings sensitive to alkaline products.
Choosing the Right Product
For heavy mineral crusts or builder’s dirt, step up to MN Power-Clean. For long-term stain protection after cleaning porous stone, seal with MN Stain-Stop.
Pro Tips
- Pre-heat shower walls with warm water; the 40 °C surface temperature speeds chemical activity by about 20 %.
- Buff polished chrome dry; any remaining micro-film evaporates, preventing drip marks for up to 48 hours.
- Include Universal Badreiniger in a weekly general cleaning cycle to maintain sealer performance.
