This stuff is a miracle for siding algae. It removed even the stuff the power washer could not and I didn't even have to get the power washer out of the barn! Please have more of this in stock. Incredible!

Product worked well, not sure why I wouldn't just use bleach since it's obviously that's what it is

This stuff is amazing. Spray on my bounce house and rinse it off and you're done.made it look like new again

Works great cleans with little effort

Great product. Must follow directions.

Worked grdat to remove algae off of our deck.

This 30 second cleaner is amazing! Spray on, wait 30 seconds, rinse...simple as that. We sprayed the siding on our house and everything came right off! No need to bring out the pressure washer. Highly recommend!

Love this product

I was really skeptical that this product would work as well as it did, but it really does work. I hope this information is helpful: Material used on: Vinyl Siding How I used it: We were going to clean our porch to prepare to put some curtains up and didn't want to have to scrub it down it down with Dawn etc. This really was a spray it and hose it down. Our front porch is yellow and white was mostly just dirty. It now looks and smells really clean. I put white curtains up. It is lovely to sit on. The product worked so well and was so easy to use that I moved onto the parts of the house that are close to the garage that are really nasty (we just moved in 8 months ago). I decided to get ahead of the person who is coming to power wash our house and did some other areas close to our porch to clean it as well. What I learned... I would suggest using safety glasses because this stuff really can spray back at you. If the area is mostly just dirty, a 2 to 1 dilution is fine. If it is really green from algae (and I had some stubborn areas), you really need to use the full concentrate and leave it and walk away for about 30 minutes. Then you come back and it is gone before rinsing. That might be different than the label recommends, but that is what worked for me. Using a 2:1 ratio on those areas was just a waste of the solution and my time on those areas.

fast and it works as advertised, excellent cleaning

Cleans very well !!

This stuff really works great. I used it at a 50/50 mix with water on my patio blocks and let it sit for 5 minutes. Brushed the heavy green areas with a deck brush rinsed and the results were amazing. The other great thing is it keeps working and looked even better the next day. Also used on my gazebo top that was turning green on the inside with the same great results. My new go to cleaner for removing green buildup outdoors. Also was great on concrete steps and flagstone walkway.

This cleaned our canvas bell tent quickly. It looks brand new! I love this product!

For years i have had to either pay someone to pressure wash my house or borrow a friends pressure washer! Well not anymore!!! I found out about this by word of mouth. I thought id give it a try, i mean if it failed id just go get a pressure washer from a friend. So i mixed 1 gal of outside cleaner with 2 gal of water and pump sprayed on my house. That combined with a garden hose and my house was shiny white again! HIGHLY RECOMMEND TO ALL!!!!!

It worked well but I’m not convinced it works better than just bleach. I believe it has bleach in it and it did stain my clothes.

Easy to use with Fantastic Results. Do not hesitate buying this product, it works!!!

Worked better than expected. The fastest I ever completed the job. Just make sure you wear some ppe.

This stuff works great. I highly recommend it. No scrubbing.

I’ve tried numerous cleaners in our drvk, pavers and concrete. I sprayed on per instructions and let sit 5 minutes. I then power washed and dirt disappeared. Cut our cleaning time by 75%. Highly recommended

Quickly removed the algae on concrete and wood deck.

Works although its really just glorified bleach. I used it on roof shingles an it removed 90% of the staining and mildew

I found that this product sort of works, but you have to use full strength to get good results. This makes it not very cost effective as a mixture of bleach, car wash, and water works just as good or better

This is an amazing cleaner that works within minutes. It does better than just power washing on concrete.

The product is the best on the market. Where clothes you don’t care about as it has a bleach component. I used it on siding, brick and concrete. Great for mold removal.

I watched a YouTube video of a guy that used 6 different kinds of treatment on different sections of his fence, then waited a month, and the section with this cleaner almost completely restored his fence. I did it to mine and the house I just bought with many years of neglect, now looks like it has a brand new fence. Spray the fence with this product hooked to the hose, then power wash, then spray down one last time for long term results. It works!!

I bought this product to clean the black & green slime that has been gathering on my concrete patio on the north side of my house for many years. I tried a 50/50 solution at first that removed some of the grime, but I used it full strength to really get it clean. I tried using bleach before getting this product and it didn't have much effect. I liked the results of using this product and I highly recommend it.

Folks, I was a general contractor and built many decks, also repaired many wooden decks. This is by far the BEST cleaner you can get and use. Spray on, give it a light brushing, wait 15 to 20 minutes and hose or power wash off. Your wood, siding, fence, concrete etc. will look brand new! I am working on a deck right now, 5 years old and very dirty, LOOKS NEW!!!

Great product - only had to spray on! No scrubbing and it worked like a charm to remove mildew on my siding .

Great cleaner. I used it to clan a wood privacy fence. My fence went grey and green to looking almost brand new. No pressure washing needed!

I had been looking for a product that was easy to use and worked. I had read the reviews and thought I would give it a try. Best cleaner I have ever used, my neighbors ask me what I did and now they plan to use it.
