Lithofin MN Outdoor Cleaner

Heavy rain, UV and frost leave your terrace slabs blotchy; algae darken joints and barbecue grease sticks to the granite step. You spray Lithofin MN Outdoor Cleaner, wait two days and rinse: the original colour pops back and the surface loses its slippery film.

What MN Outdoor Cleaner Does

MN Outdoor Cleaner is an alkaline cleaner for outdoor stone, concrete and ceramic. The pH 12.5 formula releases active chlorine that oxidises leaf stains and tyre marks within 30 minutes and breaks protein-based dirt at the molecular level. No acid means zero etching on marble (Mohs 3) while the high alkalinity opens pores in hard granite (Mohs 7) so that rinsing flushes the grime away.

When to Use

• Sandstone patio after winter - use ready-to-use solution, 100 ml/m².
• Concrete driveway oil haze - apply undiluted, 67 ml/m².
• Wood-look porcelain deck before sealing - dilute 1:3, 150 ml/m².
• Clinker garden path with leaf marks - ready-to-use, 100 ml/m².
• Follow-up to outdoor-cleaning step 1 (ALGEX) - undiluted, 80 ml/m².

How to Apply

1. Remove loose dirt. Spray or water-can spread 67-200 ml/m² according to soil level.
2. Work in with a nylon brush; keep surface wet for 20 minutes.
3. Leave 24-48 h; reaction time is weather-dependent (5-25 °C ideal).
4. Rinse with a hose or low-pressure washer from 30 cm distance.

Coverage: 5-15 m²/L. Allow 24 h drying before sealing or foot traffic; full curing ends after 48 h.

Surface Compatibility

The formula shines on sandstone, slate, basalt, concrete pavers, and bluestone because oxidative cleaning does not rely on acid that could pit soft minerals. It is also safe for outdoor marble, limestone, porcelain and cotto when pre-wetted. Do not use indoors or over vegetation; cover plants first.

Choosing the Right Product

For living algae or moss apply Lithofin ALGEX first; after 24-48 h rinse, then clean with MN Outdoor Cleaner. For long-term stain prevention seal the dry surface with MN Stain-Stop. Need an indoor deep clean? Pick MN Power-Clean instead.

Pro Tips

• Warm weather (15-20 °C) accelerates oxidation by 25 %, shortening dwell time.
• Scrub across, not along, the grout lines; this avoids detergent pooling and gives uniform colour.
• Repeat annually in spring or autumn; regular cycles stop deep-rooted stains from setting.
