Overview
Overview
Back
Osmo Decking Cleaner is a highly effective cleaning concentrate suitable for all types of untreated and oiled decking boards.
To restore the colour of wood that has turned grey / silver over time, we recommend the use of Osmo Wood Reviver Gel.
Preparation
Preparation
Back
Decking boards to be cleaned should be free from loose dirt, debris, leaves and twigs. Sweep the decked area with a stiff broom or brush to remove all loose matter before cleaning.
Application
Application
Back
Always do a test area before starting any project to assess product suitability and finish. Follow the manufacturer's instructions on the container at all times.
Mixing Guidelines
Add Osmo Decking Cleaner to water for mopping. The mix of cleaner to water depends on the amount of soiling on the surface of the wood. For a weak concentration, mix 1 part cleaner to 25 parts water; for a very strong concentration of cleaner, mix 1 part cleaner with 1 part water. Any amount between these values can be used as required, i.e 5:1, 10:1, 15:1 etc.
How to Clean Decking
- Clean along the wood grain with a stiff broom or decking scrubber, such as Osmo Decking Cleaning Brush
- After cleaning the wood deck, rinse with clean water and allow the surface to dry
Please Note: Avoid direct contact of Osmo Decking Cleaner with plants and garden ornaments.

Ineffective
Was not impressed with this product. Found it had very little effect on my decking, even applying it with the Osmo brush.

Easy to use and cleans well
Needs some hard work but it’s worth it.

Ok
Even using this a lot of scrubbing by hand was needed, and a lot of rinsing. I hate housework.

Great deck cleaner
It’s done a great job on our deck that was in very poor condition. It was hard work though, scrubbing on hands & knees

It works better than other deck cleaning products I have used
Easy to apply and more effective than other deck cleaning products I have tried.

Worked Well
Used a stiff brush and this cleaner to remove the grime, and there was a lot of it, from my decking. Once dry you can see a big difference.

Didn't think such a small bottle would ho so far
Takes working to get best results but happy with purchase and would use again
