“The composite deck had been in place for 10+ years and never cleaned. It was it pretty bad shape!! We used the Corte Clean on a cloudy day so we could allow it to soak for the recommended time without drying out. The deck isn't perfect, but the difference is AMAZING. Very little scrubbing, very little effort and the deck looks so much better. We truly were not sure what to expect as this deck was in bad shape. Still a little more work to do, but I believe with another cleaning this Spring, it will look GREAT. Very pleased with the results.

Thanks for the testimonial! Their is good reason the Corte Clean label directions state "Works best in direct sunlight between 65 to 85 F.", especially to clean a neglected 10+ year old composite deck in pretty bad shape! The key to success isn't the time Corte Clean is allowed to work, but using it in the correct conditions & carefully following its label directions. Your deck would have likely turned out perfect, if this critical label direction was followed, especially if you didn't skip the final label direction which states “When Corte-Clean® no longer turns 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 composite prior to using.)” The best way to thoroughly rinse is to apply before it rains and let the natural moisture complete the job. If it doesn't, re-apply. Perhaps this is all the remaining "work" you need to do? Once thoroughly Corte Cleaned and exposed to the sun for weathering issues even out, which generally takes 6 to 8 weeks, your composite deck should look "perfect." Don't forget to proactively Corte Clean your composites, at the reduced "routine cleaning" strength, "at least twice yearly, spring & fall, or when stains appear" if you wish to generally spend less time, labor & money keeping your composites clean.
