How to use High Performance Decking and Garden Cleaner

Before you start

Use a stiff wire brush to sweep away any leaves, moss, dirt and other grime.

Don’t wet the surface of your decking, our cleaner works much better when it’s dry.


  1. Cut open the pack and take out the sachets. Be careful not to cut the sachets!
  2. Drop the sachets into a watering can or one of our sprayers. Once sachet needs 2.5L of water.
  3. Wait 90 seconds for the sachet to dissolve in warm water or up to three minutes if you use cold water.

For general cleaning

  1. Pour or spray on the liquid.
  2. Scrub the surface with a stiff brush.
  3. Leave the cleaner for 10-15 minutes.
  4. Give the surface another scrub.
  5. Hose it down until the cleaner has washed away.

For killing algae

  1. Pour or spray on the liquid.
  2. Leave it for two to three days. This will get rid of the algae and its green colour without the need for scrubbing.
  3. Brush away any dust that may be left behind.



Inspect your decking every six months or so to decide if it needs cleaning.
