Corte-Clean® is the Safest, Most Powerful, Easy To Use, Cost Effective,
environmentally responsible, nontoxic, biodegradable, proven product for cleaning composite deck, dock, and fence materials. This is because it is designed and intended only for this purpose. It is not a product that was designed and intended to clean other materials such as wood or nonporous materials. Unfortunately, some cleaner manufacturers have added composites to the label to sell more product. Perhaps you have wasted your valuable time and money using products that do not work for this very reason.

Corte-Clean® has been proven effective by customers like you. It has been tested and endorsed by leading eco-conscious composite manufacturers, distributors, and retailers who realize its many benefits over the competition and choose to recommend our environmentally responsible, proven choice. The information on the this web site should be carefully considered. It will help guide you to why Corte-Clean® is the best choice when used to clean an expensive, long lasting composite.

A Heavily Stained ChoiceDek®
Corte-Clean® cleaning a heavily mold stained Lowe's® ChoiceDek®. This is what repeated uses of sodium hypochlorite based products do to mold stained composites. Notice how the composite is no longer spotting but is entirely covered with mold stains. It generally takes several
additional repeat applications of Corte-Clean® at maximum strength to clean composites in this condition.
The recommendation and use of products intended for cleaning wood or nonporous and other materials is the number one issue facing the entire composite industry and unsuspecting composite owners that follow these recommendations. This is especially true when these products contain sodium hypochlorite, the active biocide in chlorine bleach. When a product containing sodium hypochlorite is used to clean mold, it is generally used against the manufacturere's label directions. This includes products to be dangerously mixed with chlorine bleach and common deck cleaners recommended and used for cleaning mold. Much frustration has been experienced by composite owners who can't get their expensive composite thoroughly clean when using products containing sodium hypochlorite. Not to worry, Corte-Clean® will get the job done.

AFTER (Corte-Cleaned)
Corte-Clean® does not contain or need to be expensively mixed with the dangerous, toxic, polluting, un-healthy, corrosive, environmentally destructive, sodium hypochlorite. Be aware of any retailer or chemical company selling products containing or to be mixed with this chemical for cleaning mold. The sale and use of mold cleaning products containing this chemical are commonly known as THE BLEACH SCAM.

Before (Mold Stains)
You will not have to purchase and use other products which are potentially polluting, toxic, dangerous and unhealthy chemicals for specific staining issues. Examples of these undisirable chemicals: Oxalic Acid, Phosphates, Ammonia or Cetyl Trimethyl Ammonium Chloride. By using Corte-Clean®, you will not be taking the risk of accidently or intentionally mixing chemicals.

AFTER (1 application of Corte-Clean)
The use of Corte-Clean® will not pollute the air or environment beneath, around or downstream from where it is used. You won't risk the penalties associated with illegally using polluting chemicals on surfaces (porous vs. non-porous) or for purposes that are not legitimate. It is safe for cleaning stains from composites that drain into natural waterways such as streams, rivers, lakes, estuaries and the ocean unlike products containing sodium hypochlorite, phosphates, acids and other chemicals.
Corte-Clean® is not a pesticide, known probable carcinogen, reproductive or developmental intoxicant. Its use is far more effective on tough composite stains than unhealthy, unproven, polluting chemicals while cleaning stains that these chemicals cause or leave behind. It should not agitate breathing problems such as bronchitis, asthma, emphysema, etc. It does not have a toxic chemical smell. You will not be breathing toxic fumes that generally result in a terrible chemical headache or worse. It will not have the potential dangers of using and potentially poisoning anything living including yourself, your family, friends, children, the elderly, employees, pets (dogs, cats & birds), or wildlife when following its label directions. Once used it will not off-gas toxins or have a lingering, toxic, unpleasant, unhealthy, nauseating smell.

You will not need to worry about Corte-Clean® causing rust stains or it being corrosive to structural metal fasteners (screws or nails) and connectors supporting and holding most composites together. When using other corrosive cleaning chemicals, such as those that contain sodium hypochlorite, it will likely lead to expensive early replacement or dangerous and potentially costly failure. Corte-Clean® will not kill your lawn or plants surrounding your composite when used in accordance with our step by step bilingual directions. It cleans without the expense and labor of buying and applying multiple cleaners for specific staining issues. Corte-Clean® will save you time, money and aggravation.

BEFORE (Neglected Mold Stains)
It generally takes two (2) repeat applications of Corte-Clean® at maximum strength to clean composite stains. Enough product is provided in each Corte-Clean® container to do two (2) repeat applications. The smaller container or bag of Corte-Clean® cleans approximately 300 square feet of composite at maximum strength and the larger container cleans approximately 600 square feet. If the composite intended to be cleaned has been neglected or previously cleaned with unproven products, additional Corte-Clean® applications may be necessary. Save yourself the added cost and effort. Be pro-active and routinely Corte-Clean® your composite at least twice (2X) per year, spring and fall or whenever stains appear, especially if they are caused by mold!

AFTER (Corte Cleaned)
Corte-Clean® ONLY FAILS when our customers DO NOT read and following its label directions/instructions or do not have enough Corte-Clean® to clean the intended square footage. If the person cleaning the composite does not read and follow the Corte-Clean® label directions, it is likely that the owner of the composite may not be satisfied with the results. However, Corte LLC does guarantee Corte-Clean® when used properly by following the Corte-Clean® label directions. If you have any questions regarding the use of Corte-Clean® make sure you contact Corte LLC (415) 924-9500. We do not want any customer to be dissatisfied with the results of Corte-Clean®.
Imagine the positive impact it would have if every composite manufacturer and retailer made the simple choice to only recommend environmentally responsible, proven, Corte-Clean® to resolve all common staining issues. Imagine if every composite owner choose to only use environmentally responsible products instead of toxic, polluting, dangerous chemicals. Imagine how much better off our environment would be today and for future generations. Fortunately you have the choice, and we hope you will choose Corte-Clean® for cleaning your composite deck, dock or fence.
