Amazing Product We have Choice Decking on our porch, front steps and back steps with multiple stains/mold on all. After using many different products, Corte-Clean was the ONLY product that made any impact and removed most stains. This company REALLY does care and took the time and effort to work with me directly on how to remove the stains and care for my decking. My only regret is that I wish I knew about this product before wasting my time, effort and money on other products. Highly recommend this product and 5 stars to Greg, the representative I dealt with.
