I must admit two (2) things. This is NOT one of them but, yes, I am from the South and sometimes use more words than might be necessary. BUT, "in the South" is where decks can sour the quickest due to the heat & humidity. So, bare with me here. Or "bar" with me. One, I do squeak when I walk, I am that tight with a dollar. BUT, I am MORE than willing to pay for quality products and/or services within my budget. And I do my homework, often relying on customer reviews and Consumer Reports to try to select a best value. I purchase my hearing-aids at Costco for that reason. Two (2), I have used Corte Clean many in the past. Initially because I considered the good reviews, which are compiled by an independent company, Reviews.io, and found it to be an extraordinary product, AND a good value. After my first use, I relied on my own experience and the results it rendered. Yes, I have tried to cut costs by using some other methods of cleaning, including a soda/vinegar wash. My bad. My deck is composite and 408 sq. ft. in size. It is the scene of MANY family gatherings over the past dozen years during the summer and into the autumn, usually through Thanksgiving. It falls victim to a LOT of spillage from our grand kids and great-grand kids, plus my grilling. Too late for "long story short", but I do HIGHLY recommend the product, which I have to apply about four (4) times per year. Thanks for listening, y'all. James Paul
