Cleaner for paving stones and natural stone FRISCHER 1000 ml concentrated formula

FRISCHER concentrated cleaner for paving stones and natural stone in a 1000 ml bottle is formulated to remove dirt, moss, algae and common outdoor stains from concrete pavers, natural stone and other hard exterior surfaces. The concentrated formula allows dilution according to the degree of contamination and can be applied by brushing or using a pressure washer. The product is intended for routine maintenance and spot cleaning of garden paths, driveways, patios and public walkways.

Advantages

The concentrated composition reduces storage volume and transport needs while enabling adjustable working strength for different soiling levels. It effectively loosens organic growth and surface deposits without mechanical abrasion when used as directed. The liquid format permits application by brush or pressure washer and rinses clean, simplifying upkeep of outdoor hardscapes.

• Concrete paving stones and slabs
• Natural stone surfaces such as granite and limestone
• Garden paths, patios and terraces
• Driveways and parking areas
• Public walkways and paved communal areas

Key specifications

• Formulation: concentrated liquid for dilution
• Volume: 1000 ml per bottle
• Application methods: brushing or pressure washing

How to use

Determine dilution based on the extent of contamination: use a stronger mix for heavy moss and thick deposits and a milder mix for routine maintenance. Apply the diluted solution evenly with a brush or with a pressure washer designed for chemical application. Allow the product to act for several minutes without letting it dry, then rinse thoroughly with clean water. For stubborn stains, repeat the application or use mechanical agitation with a stiff brush. Follow safety instructions on the label and prevent runoff into sensitive vegetation or drainage where required.

Usage recommendations

Wear appropriate protective gloves and eye protection during preparation and application. Test the diluted product on a small, inconspicuous area to confirm compatibility with the surface. Avoid use on polished or acid-sensitive stones and protect nearby plants from direct contact with concentrated solution.
