Sandstone Patio Cleaner


PatioKleen is an excellent sandstone patio cleaner for combating the effects of the British weather and damp climate on your patio where the lovely look of a new sandstone patio has quickly darkened with what looks like dirt – and often is – or else black or green algae embedded on the surface.

Hard to shift, this disappointing coating can however be treated with PatioKleen very effectively and because of this remarkable product will tend to resist being darkened again.

Powerful Yet Eco Friendly Cleaner

This sandstone patio cleaner is an effective and highly innovative cleaning chemical which is non-hazardous and non-toxic and is certified as food safe and needs no PPE when in normal use.

If you are wanting an environmentally friendly sandstone cleaner, then this is a great product for you – apply with a low-pressure sprayer, roller (paint roller) or brush and scrub thoroughly with a stiff broom before leaving for half an hour or so for the cleaning to take place.

PatioKleen costs £20.00 + VAT for 5 litres and is ready to use straight from the bottle.

A pressure washer – used carefully with a rotary patio cleaner attachment and hood – helps with stubborn dirt and to wash away loose dirt after application; take care to avoid blowing out the kiln-dried sand between blocks on block paving patios or driveways.

Caring for the environment is very important and this pH-neutral cleaner contains:

  • No biocides or bleach.
  • No strong acids or alkalis

How Does It Work?

This water-based sandstone patio cleaner chemical uses nanotechnology and penetrates deeply and loosens off algae, dirt and stains by breaking the surface tension – thus our expression ‘Cleans Not Kills’ because – unlike biocides – it does not kill anything.

Biocides are almost universal in patio and masonry cleaner chemicals but there are none in PatioKleen hence the care for plants, pets, aquatic life and the environment in general. 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.

Patios treated with PatioKleen stay algae-free for longer and in our tests, sandstone absorbs rain water in a more natural way after cleaning that is almost like ‘breathing’.
