## Questions & Answers

**Q: Can this product be used safely on composite decking?  Specifically Wolf decking.**
A: I have only used it on wood, stone, and brick.

**Q: Anybody have luck on composite/Trex decking? Any warnings/tips? Thank you.**
A: I use the cleaner on my white siding, wood deck and even concrete.  The cleaner continues to work over time, I never even power wash here is Florida!  I love the stuff. (Some you put on dry and hose off, the other kind just put on surface.)

**Q: How will this affect my shrubbery which is right next to the house?**
A: Yes. It is important to do your best to avoid over spray and to rinse your plants well as soon as possible if any contact does occur. If you need something that is safe to use round your lawn and landscaping, then we recommend you use 30 SECONDS Outdoor Cleaner.

**Q: Is this safe to use on a wood deck that has been stained and sealed?**
A: I would say since the cleaner seems to work over a period of six months on on my plastic siding.  NO I would not seal it under wood.
  Rather sand and stain your deck would suffice.
  If your not sealing it, use it every 6 months and remember it takes time to work.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Worst Cases Take Months to Clear Up
*by R***  on November 29, 2024*

Grain of salt on the negative reviews. People are clearly not reading the instructions.Especially the people doing immediate comparisons to power washed surfaces.Or power spraying the product onto surfaces which wastes the product.(IF YOU NEED TO POWER SPRAY hard to reach surfaces, prepare to use 3-5x more product. And spray on a low setting )OR using the lower concentrate product on Roof Shingles, when the Roof Specific Formulas are much more expensive.This is not a product that clears up debris within hours, days, or even months in the worst cases.You don't SEE immediate results with these products.THUS THE NAME, "Spray & Walk Away."Worst cases of Staining, Moss, Lichens and Mold can take many months to clear up.And in some cases, they recommend repeated treatments.(It took years, even decades for what you're spraying to accumulate. PATIENCE is just as much part of the formula as what's in the bottled formula)If you spray it on correctly the first time, you'll be pleasantly surprised several months later.I've sprayed the much more expensive versions in past years (before the price is doubled), and in some cases the results were better after 24 months then they were after 12 months.But I was always happy after the 6 to 12 month mark.Having used the much more expensive competitor's product - and using this Spray & Walk Away product just days ago - I spray this on patios and walkways in the Autumn Season.NON WINDY DAYS ARE CRUCIAL with no cars parked nearby.(This stuff can damage auto paint. Even your neighbors cars parked on nearby driveway.)Then after Autumn Spraying, let Natire take it's course over the Winter + Heavy Spring Rainfall.The rain, snow, wind, and sunlight are what works with the chemicals to remove the debris.And in the ensuing summer months when it's bone dry for weeks on end, you'll REALLY notice the results.Spraying it on bone dry summer days is also a great application time, allowing the sun to bake the product onto the debris you're seeking to remove.Sunlight exposure is part of what makes these products work.This much less expensive "Spray & Walk Away " product is a first for me.But the ingredients are exactly the same as Wet & Forget.The smell is exactly the same.I just treated one side of a vinyl sided garage caked in moss and Lichens.And I'll expect results to really show 6-12 most later. Simple as that.No need to torture yourself sitting around and watching paint dry. Watch the manufacturers YouTube videos if you need assurances.Or just want to brag to your neighbors how you cleared everything up for less than $100.Use a $15 tank sprayer so you can control the product right down to the individual spray, making the most of the product. But also spraying into corners and crevices.(If you're using a power washer, buy 3-5x more product because you'll probably go through this much faster)Wear protective shop glasses.Prepare to go through 4-10 pairs of disposable Medical office gloves within 30-60 minutes.(For when you have to refill the tank sprayer, touch door handles / sink handles / etc )Wear old potentially disposable clothes.And when you're finished, wash the clothes and take a good shower.Even with good protection measures, you'll notice the smell on you after going through an entire bottle of this within 40 minutes.LASTLY, if you're spraying roof shingles: There's a separate, highly concentrated Roof Formula that you should consider FIRST.Roof Specific Products are more expensive. And I have yet to come across the Roof Specific Formulas in Discounted Concentrate Form.(I've made the mistake of buying the refill bottles, then finding out the refill bottles are NOT the roofing formulas. But then I used the non-rooftop formulas on everything AT EYE LEVEL, allowing me to see the product work over the course of months and years. (On pavers, limestone, and concrete.)I sprayed the Roofing Formula on my steeply pitched ranch roof.And the difference between what I could reach and what I couldn't reach is profound.The sprayed surfaces looked like a brand new roof after several months.I also sprayed it on a section of roof under shade of large trees. That section was carpeted in moss.First several months, the moss was orange / dead.6-12 mos, the dead orange moss was clearly flaking away with the weather.16 to 24 months later, that section of roof looks brand new.THE BEST PART OF THESE PRODUCTS:If you power wash your power spray the same surfaces, you get instant results. But whatever you removed starts to grow right back from day one.* You can, however, powewash first. AND THEN spray this product on dry surfaces, so ensure that your power washed surfaces look fresh and washed for years on end.When you use these spray & walk away / wet & forget type products... You're spending a lot less money. Extending a lot less effort. And you're getting long-term results.And I know this having recently sold the ranch house. The broker included High cam drone footage of the property. I could see exactly where the roof formula reached only halfway up the highly pitched roof.

### ⭐⭐⭐⭐⭐ It works
*by D***1 on May 7, 2025*

Good stuff. I have ordered several bottles. It works gradually as the sun shines and rain comes down. It is a concentrate so I use about 21 ounces per gallon in a one gallon sprayer. Easier than power washing.

### ⭐⭐⭐⭐ Easy to apply
*by S***S on March 8, 2025*

Beats pressure washing
