Product Description

GREEN TO CLEAN is a concentrated microbiological biocide specially formulated to kill and remove all types of green organic growth on external hard surfaces. Just spray and leave it to take effect. 

GREEN TO CLEAN is easy to apply and suitable for use by the DIY market or professional contractors. After application, the powerful formulation will quickly start to kill and remove organic growth, algae, mould and mildew as well as the various types of lichen that are frequently found on driveways, patios, roofs, walls and paths. 

Used frequently to kill green organic matter on

  • Driveways & Patios
  • Natural Stone
  • Tarmac
  • Roofs & Render

To ensure surfaces remain free of organic growth, GREEN TO CLEAN can also be re-applied at any time in the future to help keep external hard surfaces looking clean at all times. GREEN TO CLEAN is used frequently by homeowners as it can easily be applied with a watering can or sprayer. Only 5 litres is required to treat up to 100 - 125m.

  • GREEN TO CLEAN kills most types of organic growth on external hard surfaces.

Add GREEN TO CLEAN to water in container to avoid excessive foaming. Stir or mix the solution well before applying. Ensure thorough saturation to affected area.

Product FAQs

Q: What is your best product for lichen and heavy growth of moss on roof.


A: We would recommend Green ClearPRO. This would be a contractors choice for heavy infestations of organic growth. It also acts as a effective preventative.

Response from Alex

Q: Hi, we have some green and general dirt staining on our white outdoor patio tiles (I think porcelain but could be ceramic). Which product is best for this - Green Clear, Green to Clean or Clean Extreme? Presumably all are toxic/will kill grass if rinsed on to lawn? Many thanks


A: We would recommend Green Clear or Green to Clean, they will not damage the grass, even though it is always advised to saturate surrounding areas with water prior to use. The Xtreme Cleaner is far more aggressive and would not be required to treat the algae. It might be required if the staining is from a 'man made' product and not a result of organic matter. Hope that helps.

Response from Ricky

Q: Does it remove black spots from indian stone please? thank you


A: Green to Clean is a gentle non acid and non clorine based cleaner. Once applied, it can be left on the patio to 'go to work' over time, it will gradually kill of the black spot, but this could take a few months. For fast results, you wou need our patio cleaner Xtreme product. Hope that helps.
