Block Paving Cleaner


Our eco-friendly block paving cleaner gets rid of algae and dirt in an environmentally friendly way without too much back-breaking labour and that also reduces rates of re-infestation by algae due to superior penetration to the surface. Keeping monoblock paving looking presentable is challenging with typical issues deriving from our damp British climate where the rainfall makes conditions for algae, moss, and lichens to grow and thrive.

How This Block Paving Cleaner Works:

With our block paving cleaner, the process of cleaning is by getting underneath the algae and dirt and loosening it off for removal instead of killing it and this unique feature makes it a great product!

Most brands of exterior stone cleaner chemicals use biocides (disinfectants like DDAC) in various types to kill the green growth. In some cases they are biodegradable but toxic to aquatic life and in some cases to pets. If you are concerned about the environmental impact of your activities, you’ll think twice before you use them.

With the PatioKleen block paving cleaner there are absolutely no biocides and it is:

  1. Certified as food safe.
  2. Non-toxic and non-hazardous – contains no caustic acids.
  3. Contains no biocides or disinfectants.
  4. Uses no bleach or sodium hypochlorite.
  5. Slows regrowth of algae.
  6. Made in the UK.
  7. Needs minimal or no PPE.

You won’t want to use traditional brick cleaner acid on your block paving either – although powerful and cheap it will likely ruin or discolour the blocks.
