Corte*Clean® is the #1 Recommended & Proven Single Solution for Deep Cleaning Composite Decks, Docks, Fences & keeping them clean! Say goodbye to mold & mildew stains, black spots, grease, oil, rust, tannin’s and more in one cost effective product.

Product Details

When used at Maximum Strength, a single bag of Corte*Clean® will generally clean approximately 300 Square Feet with two (2) repeat applications. Maximum strength of 4 to 5 Scoops (maximum water solubility) of Corte*Clean® powder per gallon of warm 104 F. water is for cleaning composites of mold stains (black spots) or other difficult to remove stains from. Composites with deep stains generally require additional applications. Please consider purchasing double the Corte*Clean® for cleaning neglected composites or composites that haven’t been previously Corte*Cleaned®. Failure to thoroughly Corte*Clean® or proactively Corte*Clean® composites generally results in stains returning, especially those caused by molds when composites receive moisture. If it is your first time using Corte*Clean®, make sure you have plenty to to thoroughly Corte*Clean® composites and proactively Corte*Clean® in the future.

For Routine Cleaning, a single bag of Corte*Clean® will clean approximately 500 Square Feet, twice (2x) per year, Spring and Fall or when stains appear for a total of a 1,000+ Sq. Ft. This is what is generally necessary to keep composites clean year-round. Composites located in climates that receive routine moisture may require additional Corte*Clean® applications. Example: Spring, Summer, Fall & Winter. If stains are noticed, one is waiting too long to proactively Corte*Clean®.

Proactively Corte*Cleaning® composites, before stains become deep set or below the surface from seasonal heat & moisture, is the key to generally spending less time & money keeping your composite clean. The ideal cleaning schedule and strength Corte*Clean® is used for for your specific composites may be fine-tuned. We suggest at least twice (2X) per year to start, however it is best to proactively apply Corte*Clean® before composites receive moisture. Do not skip the final Corte*Clean® label direction which states “When Corte Clean no longer becomes dirty or discolored, it can be diluted & allowed to dry on weathered composite surfaces. Corte Clean is designed to continue to clean any time it receives moisture.  A white residue may remain until thoroughly rinsed (use a brush if necessary). Thoroughly rinse prior to using.”

Additional Information

Corte*Clean® is designed to clean the tannin’s from the wood fibers or other dead organic matter from new composites that feed fungi, such as black mold, then soak into the porous surface of most composites and continue to clean any time it receives moisture, until thoroughly rinsed. Always thoroughly rinse any remaining Corte*Clean® prior to allowing bare skin, children, pets, animals, or any person on the composite. When the composite is not being used, it is best to re-apply another coat of Corte*Clean®, especially before the composite receives moisture, and let the rain, morning dew, snow, ice, etc. naturally rinse it. Proactively applying Corte*Clean®, at least twice yearly, Spring and Fall, at the “routine cleaning” reduced strength, before stains occur, is the key to generally spending less time & money keeping composites clean.

Composites with stains will generally require at least two (2) repeat applications of Corte*Clean® at MAXIMUM STRENGTH to a properly prepped, thoroughly dry composite surface to thoroughly remove stains when first noticed. Additional applications may be necessary to remove deeply saturated or rooted stains, especially if sodium hypochlorite has been previously used to clean mold. Keep in mind, the longer one procrastinates properly Corte*Cleaning® composites, the more time, labor and expense it generally takes as the stains root or saturate deeper into composites.

If this is your first time using Corte*Clean®, you will likely need to purchase twice (2X) as much to thoroughly Corte*Clean® the underlying dirty recycled plastic and tannin’s from the wood fibers of which most composites with mold problems are made, especially if they have been neglected, previously power washed or other cleaning products have been used, specifically those that contain sodium hypochlorite or oxalic acid in an attempt to clean mold. It may take 2 to 4+ applications of Corte*Clean® at maximum strength to thoroughly dry composites in direct sunlight between the temperatures of 65 F. to 85 F. when composites are allowed to expand, to clean 300 Square Feet of composites. This will likely require up to two 2000A bags of Corte*Clean® – allowing up to four repeat applications at maximum strength. Do not skip the final Corte Clean label direction which states “When Corte*Clean® no longer becomes dirty or discolored, it can be diluted & allowed to dry on weathered composite surfaces. Corte Clean is designed to continue to clean any time it receives moisture. A white residue may remain until thoroughly rinsed (use a brush if necessary). Thoroughly rinse prior to using.” The best way to thoroughly rinse is to apply before the composites receive moisture from rain.

Note: 6′ railing sections generally require approximately 75 square feet of Corte*Clean®, 8′ railing sections generally require approximately 100 square feet of Corte*Clean®.

If you are unsure how much Corte*Clean® you need, or have any questions, please visit the Corte*Clean® corporate website at or contact us prior to placing your order. It is very important to ensure you have the right amount to complete the job and that you understand the process. If stains are still visible, especially when composites are wet, with water, or the Corte*Clean® is still turning dirty or discolored, one must repeat the application process. Failure to thoroughly Corte*Clean® composites made from wood & plastic is a waste of your time and money. If you aren’t willing to thoroughly Corte*Clean® composites, by following the Corte*Clean® label directions, please do not purchase our proven product. You won’t likely be happy.

Corte*Clean® is most effective when it is fresh! This is why each bag of Corte*Clean® is made-to-order online, and available for auto-ship with the Routine Maintenance Program. Please do not order more than you will be using within 3 to 6 months, as Corte*Clean® has a “Best If Used By” date that is one year from the date of manufacture. Store new or unused Corte*Clean® in original re-seal-able packaging, away from combustible materials in dry, cool area out of direct sunlight. Climate controlled areas below 80 Degrees Fahrenheit but above freezing and are consistent in temperature are best. Do not take Corte*Clean® on airplanes.
