Product Description

From the Manufacturer

Wet and Forget has a unique combination of biodegradable selective surfactants for moss, mold and mildew stain removal on any exterior surface. When diluted with water and applied, it immediately penetrates the unsightly stain. Each time it rains, this safe, cleansing combination reactivates to gently lift the moss, mold and mildew stain without damaging the surface. Wet and Forget is an EPA approved one step process that requires no scrubbing or rinsing. It is non-acidic, non-caustic and contains no bleach. Be patient, Wet and Forget's gentle cleaning action takes time depending on how heavy the stain is and results are visible over time. Remember good things take time, and Wet and Forget continues to clean for up to a year. No special equipment is required. Just apply Wet and Forget with a pump-up garden sprayer. After the first application simply reapply Wet and Forget at the first sign of moss, mold and mildew stains returning. Wet and Forget can be used on any outdoor surface. Some examples of these surfaces are: asphalt (blacktop), Astroturf, aluminum siding, awnings, brick pavers, composite decking, concrete, driveways, docks, fiberglass boats, fiberglass shingles, fiberglass hulls/topsides, green houses, gutters, inflatable dinghies, limestone, marble, marinas, natural stone, outdoor furniture, outdoor planters, paint surfaces, patios, patio furniture, plastic houses, recreational vehicles, retaining walls, sails, sandstone, shade sails, sidewalks, stucco, tennis courts, teak decks, textured finishes, tiles, tombstones, umbrellas (outdoor), vinyl siding, wood.

OK, brought this stuff, 2 large bottles at Costco. Figured if it was crap as I expected it would be, I'd take it back since that's how Costco works. Watered it down as instructed and sprayed one side of two stone steps which were covered in black Mildew. About a week later I noticed a definite difference but wasn't blown away by the results. It does say though, give it a few weeks. Yeah, right. However, I am about a month into leaving it and it's amazing. One side is still the black mildew and the other is about 80% cleaner and brighter. I am going to give another little spray and I reckon in 2-3 more weeks, it'll be as new. I deliberately didn't scrub it either!

So, I live in Norcross, GA. By the river and lots of mildew so this is going to be awesome but I want to know why I haven't heard much about this stuff. How the heck does it work? It says it works with the wind and rain to slowly remove ingrained stains and keep stuff clean. It does exactly what it says it does and that for me, is a miracle in itself. I have also, for fun, sprayed some shapes into my black mildew driveway and I can already see it working, I just want to know HOW :)

I first bought this product in mid-2008 after it was introduced to the US. I had tried about everything (bleach, other chemicals, powerwashing) to keep green moss and black mildew off my brick steps and veneer, concrete porch and sidewalk and pool decking. I was down to power washing (a 2 day job) twice a year and this was really deteriorating and spawling my brick. This product is truly remarkable. I applied it with no prep to black algae and green moss. In some cases the moss was up to 1/4 inch thick. It took a while, but within a week or two the moss began turning yellow, and then later turning to a powder as it died. Slowly the black mildew began to subside. The most remarkable thing was how long it kept repelling the moss and mildew. A year later, the moss and mildew has largely stayed gone. Now don't get me wrong, it is not perfect as there are still some areas that are prone to growth, but it has been almost a year. There were some really bad spots that it did not completely rid the mold, and I'm going to tackle those again this year. However, there were other spots, for example on my pool decking, where the mildew has stayed completely gone after a year. This year I'm going to try applying more frequently as it suggests in the literature, perhaps every 3 months. When I first investigated this product a year ago, I did not really believe all the hype on how good it worked. But, I can now say that this product truly works.

Used Wet and Forget on the brick floor of our front porch. Living in Florida this floor was covered with a green growth, especially following rains. As advertised, Wet and Forget did the job and it continues to remove more following each rain. The only reason I gave it a four star was it is not as efficient in cleaning a wooden swing, admittedly badly covered with mildew and mold. Great product and I will definitely order more when this is gone.

Now, two years later, I find that I only have to use this product once per year and I have enough remaining for 2012 from my original order of two gallons. I have raised my rating to five stars. This is a really great product!

I treated a portion of stone wall covered with black mold and a lot of moss early Fall of 2009. NO Scrubbing or power washing. In a week I could tell it had improved, all the moss was dead. However, the wall still looked very bad. After a month it was some better, but far from perfect. I forgot about the project and wasn't convinced the product was that good... (good thing I didn't write a review then)

Time passed winter, spring... During my spring clean up I noted an incredible change! The Treated area was like new, not a speck of moss/mold etc. I am ordering 4 more gallons.

Do not use this product to loosen and kill mold and moss before scrubbing or power washing. It doesn't work that way and you will just wash it off. Just Wet it down and reserve judgment for 6 months. You shouldn't be filling out a review until 6 months after it's use.

Update: June 2012. Still looks perfect after nearly 3 years on one area 2 on the other areas. I have not done a second treatment. Don't waist time and money on a once a year treatment.

The active ingredient is benzalkonium chloride, the same antibacterial and antifungal agent that makes the popular Lysol spray, except in a much higher concentration. This also appears to contain some kind of sudsing agent because there were soapy bubbles when I sprayed it. Benzalkonium chloride, also known as ADBAC, has been used for many decades to disinfect hospitals and household surfaces and is safe, in fact it is even used in contact lens solutions. I sprayed all of the stucco on our house and the entire wood shingle roof using a Miracle-gro garden sprayer. The runoff appears to be safe for plants because they're doing fine after I used four entire gallons of Wet and Forget a few weeks ago. I found this to be a safe and powerful way to get rid of mildew, bacteria, and fungus on large outdoor surfaces.
