## Overview

Wet & Forget Concentrate is a powerful, bleach-free outdoor cleaner that removes moss, mold, mildew, and algae stains without scrubbing or rinsing. One 128 oz bottle mixes to cover up to 2,250 sq ft and works gradually with natural elements to keep multiple surfaces clean for up to a year.

## Description

Wet & Forget is an outdoor cleaner that eliminates black and green stains caused by moss, mold, mildew and algae without any scrubbing, power washing or bleach. Just mix 5 parts water with 1 part Wet & Forget in a pump up garden sprayer. Fully saturate a dry surface with Wet & Forget on a cool dry day and leave it. That’s it! Just wet it and forget it. Wet & Forget goes to work with the wind and rain to gently clean the surface over time. Green stains generally clean up within a few weeks, a few days with rainfall. Black stains or heavy stubborn stains may take 6-12 months to fully clean up. Be Patient, Good Things Take Time! Wet & Forget properly cleans surfaces, so they are likely to stay clean up to 1 year or longer. Repeat application yearly or when new stains appear to maintain a clean surface. Wet & Forget contains no bleach and is safe to use on any outdoor surface including any type of deck, siding, roof, walkway, patio, brick, and cement. Gallon Concentrate makes 6-Gallons and covers 750 - 2,250 sq. ft. depending upon severity of the stain and porosity of the surface. Wet & Forget - the easy way to clean all your outdoor surfaces

Review: Excellent product - I have used this product on driveways, unpainted fences, rock retaining walls, concrete blocks, brick walls unpolished landcape granite stones, paved pathways and composite decks. It cleans so well, that it eliminates need to pressure wash. Concrete Driveway was almost black, before application, however, now it has a newly laid look. I have been using his product near plants (not edible) and have noticed no damage. Yes, its hard to control overspray 100% of time. I love that rain, snow, wind are also the cleaning agents and I dont need to waste any additional water in cleaning. Water is expensive. Rock retaining walls look like newly installed and just made, after using this product. I have had people think 10 year old walls were installed a month ago. I also use it on pebble bed to keep cobblestones looking clean. It works. It keeps fences clean even after 2 years of application. It doesnt seem to attract as much moss, lichen mold etc. It does give it weathered clean light grey/whitish look, which I dont mind. It does NOT give a fresh brown wood look, like if you pressure washed it. One needs to be patient after using the product. It works slowly over a year. The best time to apply it is dry fall day, so the rains can help with cleaning, not to mention winter snow. After that once a year to year and a half, maintainence is more than enough. And come spring and summer, you can enjoy the cleaner surfaces. I also used it on cedar roof. I did excellent job with it. However, the roof was old and leaked after this application, requiring me to change the roof. My theory could be a combination of any: 1) It actually started eating the moss and mold between cedar shakes, that was actually like a barrier for water somewhat. my cedar shakes had only 2 to 5 years of life left and potentially cleaning it, reduced its life 2) I walked on roof to apply the product which could have strained old shakes. - There are special shoe fasteners that I overlooked wearing. The house damage was negligible and very promptly addressed, though I wish I didnt have that extra expense. That said, I would stay out of the roof - for the rest of my life and have a professional take care of business. I almost always have extra bottles on hand. It is extremely helpful to have a battery sprayer. I used a 1 gallon manual one for years and it works just fine. Battery sprayer is way faster and probably reduces the time by three quarters. i have not tried the other product from wet and forget that connects to the hose. Many have found difficulty in the way the spray works. I dont want to try something new when this works great. Moss, slowly wears off. Lichen growing on organic surfaces is the hardest, but it loosens that up too. I noticed that the lichen dries up and does not grow even after 2 years of application. I have used this product over 10 years now and this is a cumulative review.
Review: THIS STUFF WORKS - effect lasts a long time too! - I live in the panhandle of Florida. Item arrived with a tag attached which said, in so many words, "Read the instructions thoroughly, or don't complain if it doesn't work." I took that to heart and was very meticulous in how I mixed and applied the product. Using a garden sprayer, I applied product to the sidewalk (28-ft 6-inches) immediately leading to my front porch on 1 October. I stopped there and did not treat the remainder of the walkway, so that I could see the contrast between the area treated and what wasn't treated (20-cups water and 4-cups product). One week later (9 Oct) I treated the same area again, this time with 25-cups water and 5-cups product. To date, I can see no significant difference. I do see small quarter-size blotches that appear to be cleaner, but there's a long way to go before I can declare the sidewalk as noticeably cleaner. Probably no fault of the product. It may not be intended to treat the type of stain on my sidewalk. Or, maybe I'm being too impatient! In any case, if I see any marked improvement, I will make it a point to update this review. I opted to try this product instead of using my pressure washer again because, although the pressure washer works, it tends to eat away at the surface of the concrete. Now granted, the instructions on the product state: "REACTION TIME - Once treated...stains may take up to 6 to 12 months to come clean in the very worst case scenario." But, this may not help folks who get complaints from their Homeowner's Assn. asking that they clean their sidewalk immediately. I have a little less than half-gallon remaining, which I will use. But, unless I see a significant difference in 6-months, it is unlikely that I will buy this product again. Results may be different for others. 11 Dec 2014 - Still no significant difference between the treated and untreated sidewalk. I have about a half-gallon remaining, which I will use on my brick to try to control the mold that's returning after a pressure wash I completed almost a year ago. 10 Dec 2015 - I upgraded my review from 4-stars to 5-stars. All I can say is: "THIS STUFF WORKS." A full year after applying it to my sidewalks, I have the cleanest pavement in the neighborhood! That includes my neighbor, who just had her sidewalk pressure washed earlier this year. It may take a while to work, but the effect is long lasting!

## Questions & Answers

**Q: Any luck with just dirty landscape bricks or is it just for mold and mildew??**
A: I doubt that W&F would clean ordinary dirt, soil, grease, and similar stains from landscape bricks, but it does do a great job of removing mold, mildew, fungus, lichens, moss, etc. My experience with W&F is that when it kills the mold, mildew, fungus, moss, etc., with time the deposits of discoloration that those organisms put on the surface will also come off. I have an area of pavers by the side of my house that is in the shade almost all year so it tends to grow mold/mildew and lichens. When I apply W&F, almost immediately the mold/mildew changes color from black to brownish color, and gradually after a few weeks the brownish color goes away, too. Similarly with lichens and moss: First it changes from live green color to a dead brownish color, and then it goes away completely. This stuff is fantastic for killing "dirty" organisms like mold and mildew and also for removing most of the stains they leave behind, but it won't clean ordinary soil, grease, etc.

**Q: Can I spray thiis on my back deck today, and paint the deck 4 days later without washing?**
A: Wet & Forget does not work that fast. If you were to paint your deck four days after applying this product you would be wasting your money because Wet & Forget  would not work at all. In order for Wet & Forget to work it must be exposed to the elements, e.g., sun and rain. I would pressure wash the patio lightly, let it dry completely and then paint or stain it.

**Q: Any luck with this cleaning mildew off of painted brick?**
A: Used on roof, vinyl siding, painted concrete. Found it to be better than other products that made similar claims, just use as instructed.

**Q: apply wetandforget prior to restaining ?**
A: I have only applied it after staining. I suggest you contact the manufactureran ask your question.

### ⭐⭐⭐⭐ Wet & Forget... Too good to be true?
*by B***K on June 25, 2014*

I heard about this product on a DIY talk show that I listen to on the weekends. It sounds too good to be true, but I'd hate to miss out on a possible good product! :) The pros: + VERY easy to apply with a spray bottle or pump sprayer. + Work great on exterior brick surfaces, like chimneys. + Advertised - 1 gallon concentrate makes 6 gallons of ready to use product. Covers approximately 750-2250 square feet. + Advertised - non-caustic, Non-acidic, Contains no bleach. + Advertised - safe on any outdoor surface. + Advertised - one step process... Wet & Forget! + Advertised - EPA approved one step process that requires no scrubbing or rinsing. + Advertised - safe around plants. + Advertised - continues to clean for up to a year. + Advertised - can be applied at any temperature above 32° & no rain is expected for 4-5 hours. The cons: - Update - 2016 - The price has really gone up in the last year, making this product VERY expensive! Yes, this is a concentrate & makes 6 gallons, but that over $5 a gallon! I dropped one rating star for this. - Work very s-l-o-w-l-y! Don't expect instant results on everything this product is applied to. It could take a month or longer for visible results. - Slight bleach like smell when it's first applied. Not bad, but not scent free. Closing comments: ▪ I sprayed the side of a shed & fencing that had green algae on it. By the next day, it wasn't green, looked white, which should wash off when it rains. :) When I was reading the instructions on how to dilute the concentrate... 1 part Wet & Forget Outdoor to 5 parts water, I thought there had to be easier instructions. I found this on the Wet & Forget website FAQ (Frequently Asked Questions). ▪ For a 1 gallon container or sprayer, add 2-1/2 cups (20 oz.) of Wet & Forget Outdoor concentrate & fill with water to the 1 gallon mark. ▪ For a 2 gallon container or sprayer, add 5 cups (40 oz.) Wet & Forget Outdoor concentrate & fill with water to the 2 gallon mark. ► Update - June 25, 2014 ▪ sprayed the green on the fence & on the concrete under our hose reel yesterday. Today, all that green is gone! Not everything I sprayed shows this kind of result, but so far, I'm impressed enough to up my product rating to 4 out of 5. :) ► Update -November 11, 2014 ▪ We sprayed the driveway + sidewalk yesterday & I can already see it working on the driveway! The long range plan is not having to pressure wash the algae off the concrete in the Spring. :) ▪ I just ordered another gallon so I'd have it on hand, ready to use. ► Update - November 18, 2015 ▪ Since I started using Wet & Forget on the sidewalk & driveway, I haven't had to do any power washing in years! :) ▪ This product is on the expensive side, so I shop around when I need more. The last 2 gallons I purchased cost me $24.97 a gallon at the Home Depot. If you buy 2 gallons on-line, the shipping is free! :) ► Update - March 9, 2016 ▪ I've been using this for years & it works as advertised. The down side is how expensive it's gotten! Last year I paid about $25 a gallon, this year it's $34 a gallon! ▪ The best price I could find this year is here on Amazon & in my opinion, it's expensive! :(
