The science behind our products

Over the years the perceived wisdom has been that the stronger the cleaner and the harder the pressure, the more chance you had of removing black spots from your stone. Nothing could be further than the truth.

Acid-based cleaners and endless pressure washing will permanently damage your stone. This approach will cause short and long term damage to plants in the surrounding area.

Sandstone is sedimentary; it cures in layers and splits in layers. The vibration caused by pressure washing causes these layers to delaminate, resulting in destroying the surface and breaking the stone.

Patio Black Spot Remover gently removes black spots, completely restores the colour to garden stonework, of any age, and prevents the return of black spots. Our products are biodegradable and acid free. Our expertise in stone led us to develop this unique system and it’s why top garden centres throughout the UK have chosen to stock our brand.

To keep your patio free from black spots after they've been removed , apply our Patio Black Spot Preventer for all stone types. When used annually, Patio Black Spot Preventer will prevent re-infestation of black spots for good. The Patio Black Spot Preventer will also remove any green algae within 3-5 days. You simply dilute, spray and leave on the stone to work its magic. There is no need to pressure wash.

Due to strong demand from the Australian market, The Patio Black Spot Removal Company LTD expanded its operation, with the creation of The Patio Black Spot Removal Company PTY LTD, in 2015.  With its strategically based manufacturing facility in Sydney NSW, orders are dispatched and delivered within 3-5 days.
