GREAT PRODUCT

If you have screens that are green (Florida) , this works ! We are in a drought area and can't pressure wash right now . I used this product and it cleared up the green. Helpful hint , I put it in a pressure sprayer instead of the Hand sprayer that it comes with . For big areas it's much easier .

I had a bird nest in a part of the gazebo curtain and made a complete mess of the curtain and rocking chairs. Sprayed this cleaner on and walked away like it says. Well, the curtains and rockers cleaned so well that I told neighbors about it. I highly recommend.

Great product

This is a great product. It performed better than I even expected. Used it on my outdoor rug on my deck. Worked perfectly. I also used on my sidewalk and gets no sun and was turning green. Again, this worked perfectly and it looks like brand new Concrete.
