To prepare decking or other garden wood for cleaning with Ronseal Decking Cleaner, first remove any debris including leaves, twigs, soil, weeds and large amounts of moss and mould using a stiff brush. Do not wet decking.

Always do a small test area before starting any project and follow the manufacturer's instructions on the packet at all times.

How To Clean Decking

  1. Remove the cleaning capsules from the outer packaging
  2. Cut the inner case to remove the capsules - be careful not to pierce them if you use scissors
  3. Place one capsule of deck cleaning solution into 2.5 litres of warm water or two capsules into 5 litres of warm water (Warm water will allow the decking cleaning capsules to dissolve more quickly)
  4. Stir and leave the capsules to dissolve for 90 seconds (3 minutes in cold water)

How To Clean Algae From Decking

  1. Once diluted, apply to areas needing treatment using a watering can, Ronseal Sprayer or a brush
  2. Allow to dry fully
  3. After 2-3 days any green appearance will have disappeared
  4. Clean the wood after application by using a brush to clear away any remaining dusty deposits

How To Clean Moss and Mould From Decking

  1. Apply the cleaner with a watering can, Ronseal Sprayer or a brush
  2. Scrub the deck well with a stiff bristle brush and leave for 10-15 minutes
  3. Wash off with a brush and water or hose down ensuring all residues are washed away

Please note: When using this product, take care to protect plants, fish ponds, rivers and drains from contamination. This product may remove partially deteriorated or flaking coatings when applied to clean decking.

Q. Can I use Ronseal Decking Cleaner to remove the old decking stain or decking oil from my deck?

A. Unfortunately not. This product has been designed to clean and remove mould, algae and fungi. If you want to remove an existing decking stain or decking oil, you will need to jet wash the decking or use a decking stripper / remover.

Q. Is it safe for my plants?

A.This product is hazardous to plants when wet but safe when fully dried.

Convenient and it works by Michael Lynch

Used to prepare decking prior to oiling with coloured oil. Cleaner sachets dissolved as claimed, I used warm water, and applied using a watering can. Stiff brush over did the rest.

Excellent product by David Kelly

I used one sachet at a time brushing on with with a Harris brush. I left it 15 minutes and brushed (scrubbed) again. Worked well and left the decking ready for staining.

Does the job by David Munro

this contains phase-transfer surfactants, and is very useful in situations where acid-based algicides might cause corrosion on adjacent surfaces

Better than buying the tins by Philip Asselin

Cheaper than the 5L containers and was very easy to use. Definitely worth cleaning the decking with this first as a lot of grunge came up.

Nice item by Kuljit Jaye

Cleans well. Read the instructions carefully. Works best if you leave the cleaner for a couple of days for it to work in to the molded area.
