When used at Maximum Strength, a single bag of Corte*Clean® will clean approximately 300 Square Feet with two (2) repeat applications. Maximum strength of 4 to 5 Scoops of Corte*Clean powder per gallon of water is for cleaning composites of mold stains (black spots) or other difficult to remove stains. 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® composites generally results in stains returning when composites receive moisture.
For Routine Cleaning, a single bag of Corte*Clean® will clean approximately 500 Square Feet, twice (2x) per year, Spring and Fall or 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.
Proactively Corte*Cleaning® composites, before stains deeply saturate or occur from seasonal moisture, is the key to spending less time and money keeping your composite clean. The ideal cleaning schedule for for your composite may be fine-tuned as you learn more. We suggest at least twice per year to start.

Corte*Clean® is designed to clean the tannins from the wood fibers or other dead organic matter from new composites that feed funguses, 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. This is the most effective method to keep composites clean for longest period of time. 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, before stains occur, is the key to spending less time and money.
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. Keep in mind, the longer one procrastinates properly Corte*Cleaning® composites, the more time and expense it generally takes.
If this is your first time using Corte*Clean®, you will likely need to purchase twice as much to thoroughly remove mold stains or other difficult to remove stains. To clean a seriously neglected mold stained 300 Square Foot composite, may require two bags of Corte*Clean® - allowing up to four repeat applications at maximum strength.
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®.
