This stuff does exactly what it says. I really think it works better than the JoMax I used last year.

Excellent on Vinyl Siding
This is great cleaner for vinyl siding. It will spray to the top of the second floor with ease. This bottle is just about enough for both ends of our cape. Will need to buy more for the front and back. Can not believe this works so well with zero scrubbing! Awesome!

Sprayed on, let sit, washed off. Did an amazing job

GONE in 45 seconds
I had used this item before and it did a great job when applied with my backpack sprayer. BUT WAIT....I saw THE HUGE display of this product as I walked in my HD. Sprayer and refill SO convenient right! GREAT! A HOSE END SPRAYER. I set out to clean my very small painted wood deck (7x10) and 14 steps. It took longer to attach and set up the spray area than the spray bottle contents lasted. The bottle was empty before I got to the bottom of the steps. I guess what got me upset was when I went to refill the sprayer and RE-READ the instructions... NOT REFILLABLE. I just feel taken by the HD. I may have bought TWO sprayers if I had read about SINGLE USE. The stuff did clean the deck, BUT the product was GONE in SECONDS

this is an incredible product. it turned my outdoor patio stones from moldy grey back to their original bright golden color. I mixed 2 parts of this with 1 part of water (not 1:1). I sprayed and left it on for 10 min, then scrubbed with a brush and reapplied .This time I left it on for 1-2 weeks before rain washed it off. We don't walk on that patio daily so letting it sit and work wasn't an issue. Two applications about one months in between. No power washing in between.

Really works in 30 seconds
Placed a 50/50 mix in sprayer. Almost immediately started to see results. Try not to spray your pressure treaded post too much as they will remove the paint off those too.

Great product!
I was kinda skeptical, when I was looking for some product, which can help me to clean the mold of the flowers bed stones. And now I would like to share the result I got. And this is only after 1 time using. Very easy to apply, I held it for for about 15 min, scrubbed a bit, rinsed with water and here it is. I’m really happy and going to apply this product every months as a routine just to refresh the stones.

This stuff works
I tried this because I bought a property and the fence was covered in black mold and the fence it self us about 17 years old. I didn't have high hopes this was 1 treatment of our fence. I am pretty impressed. Ithink one more treatment and it will be golden but the difference is hufe already.

I bought small one and used already, then this is refill for the first bottle. My screen is really high, so I sprayed and wait 20min to rinse with strong water pressure machine. It was not perfect because my screen was very dirty, so I bought second one. If you use this at least once a year, you keep your house nice and clean.
by Kazumi
Amazing!
My gutters were dirty and I wanted to clean them up. This stuff worked so great I cannot wait to use it on other things. Sprayed it on and within seconds you could see it working. I took a scrub brush and did a light scrub and then rinsed them off. They look new. It is strong so I’d be careful to spray in well ventilated area and be careful when coming in contact. I would highly recommend this stuff
