Wet & Forget Outdoor Moss, Mold, Mildew, & Algae Stain Remover Multi-Surface Cleaner, Xtreme Reach Hose End with New & Improved Nozzle, 48 Fluid Ounces

Great spray. Works perfect. A quick spray down on the side of my house and leave it alone just to see the difference within a 24-48 hour period. It doesn’t harm my grass or my pets. Doesn’t have a harsh smell to it and don’t burn my skin if I get a little on me. It works fast and cleans the green algae off the side of my home like a professional. Looks great.

Effective and efficient product. Have been using this product ( Wet & Forget), for the past 8 years on a two story colonial house that was always plagued with mold on the north side ( non sun facing), and just one coating each year has totally eliminated all the mold and NO regrowth. Had previously tried power washing with no positive effect until reading about this product. The far reach nozzle eliminates the need to use a ladder, and at age 77 a truly great benefit, and the cost is less than 5% of what a house washing company quoted for the job. It is imporatnt to shake well before use, and good to wear a hat and eye protection but nothing else.

Very effective for siding and trim. Not so much for concrete driveway

Great product for cleaning spouting, gutters, siding, decking and concrete. Pretty much works like the name implies: wet and forget. Cleans dirt, mold, mildew and the usual stains caused by everyday exposure to the elements.

You must read the fine print and believe it. It says “Green stains clean up within 1-2 weeks, black stains or heavy, stubborn stains can take several months, long-established stains may take 6-12 months.” My house has vinyl siding which has been cleaned numerous times using a chlorine based vinyl siding cleaner. I applied this new product last month and I have seen virtually no improvement. Also on a totally windless day the spray might possibly reach 20 foot, and that is with the narrow spray nozzle. If there’s any wind, you’ll be lucky to get 15 feet. If you put on the wide area spray nozzle you’ll probably only get your face wet with even a small amount of wind. The product foams, and when you raise the sprayer, the product doesn’t dispense well, so when trying to hit higher levels, you’ll get mostly water, and that is with a full bottle of liquid. Today I applied 2/3 water +1/3 chlorine bleach, and sprayed the front of the house and it cleared up almost as I was spraying! The stains on my house were not what is described as long and established stains, but if they were I didn’t have a year to wait and see if this product worked. For the price, I’m very disappointed, not only in the liquid product but the sprayer.
