Some manufacturers are still recommending using chlorine bleach or wood deck cleaners containing oxalic acid on their composite materials to remove mold and other staining problems. This is like running diesel fuel in your gas powered vehicle. Eventually you will destroy your composite with these type of cleaning instructions.
Some manufacturers go one step worse, they recomend mixing chlorine bleach with other chemicals. This is extremely dangerous & violates numerous EPA Federal Laws
OSHA does not recommend that you use CHLORINE BLEACH on porous surfaces such as composite decking.
Corte-Clean @ www.compositedeckcleaner.com is spacifically developed to clean composite materials and is recommended by Trex and other quality composite manufacturers.
Corte-Clean was developed spacifically for all composite materials. When you use Corte-Clean, the mold takes up to 5 times longer before it comes back. It is environmentally friendly and will not fade colored decks like chlorine bleach.
The reason that mold grows back so fast when you use chlorine bleach is because all it does is remove the spotting. It does not get the mold "root." It actually waters it (store bought chlorine bleach is about 95% water) and makes the problem worse and come back twice as bad.
Check out the Corte-Clean web site and enjoy your composite deck!!!!!
