Composite Deck Cleaner

Composite Deck Cleaner

It is said “You only need 2 tools to clean a Trex deck: a hose in one hand and a beer in the other”. Trex decking is now only available in the 3rd generation high performance capped decking. So a specialised cleaning product is generally no longer needed. But for those of you who purchased a 1st generation (un-capped) or a 2nd generation (pvc decking) then you will probably need this environmentally friendly cleaner.

Corte Clean® is a proven single solution for deep cleaning composite decks, jetties and fences! It will remove mold and mildew stains, black spots, grease, oil, rust, tannins, tide marks, water marks and more. 1 packet of Corte Clean® generally cleans 28 square meters and maintains approximately 93 square meters of surface area.


When used at full strength, a single bag of Corte Clean® will clean approximately 28 square meters with two (2) repeat applications. Maximum strength is for cleaning composite decking of mold stains (black spots) or other difficult to remove stains when they are first noticed. Composite decking with deep stains generally require additional applications. Please consider purchasing double the Corte*Clean® for cleaning neglected composite decking or composites that haven’t been previously been Corte Cleaned®. Failure to thoroughly Corte*Clean® composites generally results in stains immediately returning.

For Routine Cleaning, a single bag of Corte Clean® will clean approximately 46 square meters, twice (2x) per year, Spring and Autumn. This is what is generally necessary to keep 1st and 2nd generation composites clean year-round. Composite decking located in environments that receive regular moisture may require additional Corte Clean® applications. Example: Spring, Summer, Autumn & Winter.

Proactively Corte Cleaning® composite decking, before stains occur from seasonal moisture, is the key to spending less time and money keeping your composite deck clean. The ideal cleaning schedule may be fine-tuned as you learn more. We suggest at least twice per year to start.
