Exterior Stone Cleaner

How StoneKleen Can Help

Having a powerful and pH neutral stone cleaner that will not ruin natural stone or marble is very important to maintain the natural beauty of the stone. This is a very innovative chemical that uses no caustic acids, alkalis, biocides, or bleach – among other factors this means your metal fittings are safe from corrosion that would typically come from brick acid.

The StoneKleen chemical ‘cleans not kills’ in contrast to most biocide-based chemicals that are deadly for aquatic life and sometimes even for pets; it won’t kill plants or grass either.

It works by using nano-size energy packages that penetrate and lift off the dirt or algae by breaking the surface tension that holds it on the substrate. There is also an added bonus of keeping the cleaned area free of algae for longer than biocide-based chemicals.

Exterior Stone Cleaner

Many ‘dirty’ looking patios or stone walls are suffering from an invasion of living microorganisms called algae that thrive in our damp climate. With a generous application of StoneKleen they are loosened off – along with dirt – ready to be washed away.

Non-corrosive, non-acid, non-toxic, and non-hazardous, this exterior stone cleaner is even certified as food safe and is safe to use near a water course. It is supplied in 5 litre bottles as a ready-to-use cleaner.

Use of a pressure washer in conjunction with use of StoneKleen is helpful. Pour on or apply with brush, sponge, roller, or sprayer, saturate the surface well and then agitate with a stiff brush. If sprayed you will benefit from more than one coat, ideally wait half an hour before rinsing off.
