RUSTINSRustins Composite Decking Cleaner - Effective Mold and Mildew Remover | Deep Cleaning Solution for Decks, Patios, and Outdoor Spaces 4 litre

Used on composite decking, approx 20sq meters. Was not very heavily soiled but did have some green algae and lichen. I'm not certain how this would perform if you didn't put a bit of labour into it but in order to get the results I did its probably worth a bit of effort. I power washed the surface the day before treatment. The day I chose to do it, amazingly the sun shone and the application dried out quickly - I not certain how this affected the efficiency. The area I had used up almost all the product. I used a sprayer and applied reasonably heavily. I allowed the 10 minutes as per the instructions but by that stage a lot of the surface was dry. I then scrubbed with a deck scrubber trying my best to spread onto the dry areas. As per the instructions I left it a further 30 minutes and power washed again. I also used a rotary spray attachment on the power washer and this definitely agitated the the product. I rinsed again with the washer and swept off with the deck brush. Some of the lichen did not remove but possibly due to the fast dry off but overall I was very happy with the results. I would buy this product again.

Use a decking scrubber when using the cleaner. Stubborn stains still take some getting off.

Cleans of all dirt of composite decking.Looks like new

Does what it says on the bottle

Absolutely brilliant! My Husband cleaned the Decking with the Jet wash firstly but that didn't remove the dirt from the grain on the Composite decking so we purchased this and it was effortless the second time he used the Jetwash the Grime just lifted off before your Eyes after 20 minutes of leaving it soaked in this Cleaner, My Husband said he wouldn't really of needed the jet wash after using this Solution he said the Hose would of lifted it off with this Solution applied, have bought another Tub to store for when we need it next!

one tub not enough. Good product

After extensive research for a good cleaner for my decking. I used this product on my not so dirty grey composite decking. applied as per instructions, neat onto the area, left for 19 minutes, agitated vigorously with hard brush and washed off the area with clean water. many green/algae marks and stains still present. Very disappointed..

I've used this before and it does a very good job, good stuff for the job.
