Dust, pollen, dried drips or soot from an evening by the fire – concrete outdoors picks up all sorts. AKEMI Stone Cleaner is an acid-free concentrate that loosens and washes such dirt away without harming the surface of concrete or stone.
Concentrated cleaner for concrete and natural or artificial stone, acid-free, 250 ml.
And dirt does not stand a chance
After winter, after the spring pollen season or before the first garden party, your table deserves a thorough clean. The stone cleaner deals with everyday dirt as well as oil and grease, wax residues, soot and rubber marks – in other words, everything a terrace can collect.
It is a concentrate, so a small bottle lasts a long time: for routine care you dilute it heavily with water, for tougher dirt less so. It contains no acids, phosphates or alkalis, which makes it gentle on GFRC concrete and natural stone.
Concentrate
Dilute with water from 1:1 to 1:500, depending on the dirt.
Acid-free
Gentle on concrete and natural stone.
For all kinds of stone
Concrete, marble, travertine, slate, granite and tiles.
How to use it
Dilute the cleaner with water according to how dirty the surface is – from 1:1 for heavy dirt to 1:500 for routine care – and apply it. Leave it to work for 10 to 20 minutes.
For heavier dirt, help it along with a brush or sponge, or repeat the process. Finally, rinse the surface thoroughly with clean water.

Before impregnating
The stone cleaner is the ideal first step before AKEMI Nano Effect: the surface must be clean and dry for the protection to soak in evenly. After cleaning, let the concrete dry for 1–2 days.
Do not use the cleaner on rubber or plastics that are not solvent-resistant.
