Natural Stone Cleaner – 5 Litre



Our natural stone cleaner chemical is not caustic, corrosive, or acidic and contains no biocides, acids or bleach. Having a pH neutral outdoor natural stone cleaner which is effective and will not damage the stone is very important to maintain the natural beauty of the stone while effectively cleaning it.

Product Description

Increasing demand for environmentally friendly and safe-to-use yet effective cleaning chemicals in cleaning of stone has led to us producing StoneKleen, an innovative cleaner chemical that can make your life easier and safer. It is available in both 5 litre and 20 litre jerrycans with quick delivery UK-wide.

How Does StoneKleen Work? One of our motto’s is ‘Cleans Not Kills’ and our natural stone cleaner does this in contrast to biocide-based cleaners that are for deadly for aquatic life and less than ideal for lawns or flower beds. It works by using nano-size energy packages that penetrate and lift off the dirt or algae from limestone or granite.

It does this by breaking the surface tension that holds dirt or algae embedded on a substrate with the added bonus of keeping the cleaned area free of algae for longer than biocide based chemicals. We also offer a 20 litre ready-to-use and 10 litre concentrate option – see more here.

Many a ‘dirty’ looking patio, headstone, or natural stone wall is in fact suffering from an invasion of living microorganisms called algae that thrive in our damp climate; with StoneKleen applied generously they are loosened off ready to be washed away by hose or just rain and the weather over time.

The cleaning action is powerful yet non-corrosive, non-acid, non-toxic, and non-hazardous and this cleaner product is even certified as food safe and is safe to use near a water course. It is supplied in 5 litre bottles or 20 litre jerrycans as a ready-to-use cleaner and ideal for patio and concrete and hard surface cleaning.

Apply the ready-to-use strength natural stone cleaner by pouring on or with a brush, sponge, roller or low-pressure sprayer, saturate the surface well and then agitate with a stiff brush. If sprayed you may benefit from more than one coat, ideally wait half an hour before rinsing off.

Use of a pressure washer in conjunction with use of StoneKleen is normally helpful for outdoors but older stone masonry needs care and a low pressure setting and it is a good idea to test an area first.
