Q. Can I use Barrettine Decking and Patio 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 finish stripper and remover.

For me , on old decking did not totally clear surface adequately for deck oil application
As previously stated might need a number of applications to get good results.
Maybe better on stone surface

Very poor performance
The product was not very good on wooden decking at all. Tried it three times and gave them a good scrubbing as the instructions said and washed it off and made very little difference.
It was okay on concrete coloured slabs but not the best results I’ve ever had. Far better products out there with a lot less effort. Sorry about being negative this product but you asked me for my opinion.

Not what I expected
First time using this product to clean my decking. It was ok but have used other cheaper well known products and had the same result.
Probably wouldn't buy again unless on offer

Excellent, extremely good value for money
In the top three products for its type that I have used in recent years.

Great product, good seller & well packaged
It works really well on clearing Algae on Patio's, driveways, pathways etc, and actually keeps working long after application to help stop it returning.

Fantastic product,
I'd planned to repaint some of the decking, but didn't need to do it all thanks to this amazing stuff

First Class
First time I've used this product and found the results excellent which made light of the work needed to remove moss and build of dirt on my decking. Have used other cleaning products previously which required a lot more effort and time to achieve results. I highly recommended this product .

Cleaned the decking
Used it before I oiled the decking. Did the job.
