How StoneKleen Can Help

Having a powerful and pH neutral stone cleaner as part of our stone cleaning products 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 and for these reasons is ideal as a cleaner for heritage stonework, masonry or listed buildings, statues and monuments.

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 and 20 litres jerrycans as a ready-to-use cleaner.

Exterior Stone Cleaner

Use of a pressure washer in conjunction with use of StoneKleen is generally helpful and a garden hose helps to rinse off dirt and algae. Pour the concrete slab cleaner on or apply with brush or sprayer, saturate the surface well and then agitate it with a stiff brush. If sprayed you will generally need more than one application and a generous volume of detergent on the substrate, wait 15 minutes before rinsing off with plenty of water.

How Does PatioKleen Work?

This water-based Indian sandstone cleaner chemical uses nano energy packages to penetrate and loosen off algae, dirt and stains by breaking the surface tension to dislodge and lever off soiling. Biocides are almost universal in stone cleaner chemicals but there are none in this Indian stone cleaner, meaning much-improved care for aquatic life, the operators using the product, pets, and the environment.

The nano-energy packages in the chemical can be compared to piranhas in the River Amazon that attack and tear dirt away like piranhas would feed by tearing meat off the bones of their prey.

Indian sandstone treated with PatioKleen stay algae-free for longer and in our tests, sandstone absorbs rain water in a more natural way after cleaning.

How To Use It:

After brushing debris and moss off the surface simply pour the product straight from the jerrycan or spray on generously to an area of say 6 or 10 slabs, if it is a hot day then hose over the area to be treated to wet it first. Brush in the cleaner with a stuff broom in order to agitate and help penetration, wait about 15 minutes or so and then rinse off with a hose or pressure washer.
