Ronseal High Performance Decking and Garden Cleaner

An easy way to keep you garden looking great 

Our cleaner will kill any algae and remove any mould or dirt from just about anything. Simply dissolve our sachets in water then you’re ready to go.

Where can I use it?

Bare and treated surfaces. Great for decking, patios and garden furniture.

How much will it cover?

When both sachets are diluted, 5L will cover up to 24m2 

Before you start

Sweep off any leaves, dirt, moss etc with a stiff brush. Don’t wet the surface, our cleaner works a lot better when it’s dry. 

Using Decking and Garden Cleaner

First, cut open the pack and take out the sachets. Be careful not to cut the sachets. Then drop them into a watering can or one of our Sprayers. One sachet will need 2.5 litres of water. Two sachets will need 5 litres. It’ll take 90 seconds to dissolve in warm water. Or up to 3 minutes if you use cold. 

General Cleaning

Pour or spray on the liquid. Scrub the surface with a stiff brush then leave it for 10-15 minutes. Give the surface another scrub and then hose it down until the cleaner has washed away. 

For killing algae

Pour or spray on the liquid and leave it for 2-3 days. This’ll get rid of the algae and its green colour without the need to scrub. Then brush away any dust that may be left behind.
