Absolutely Fabulous!
I have used this for cleaning the gutters on the house, cleaning my metal shed and my PVC fence.  Many more uses that have not tried yet.  It does exactly what it says....works in 30 seconds....then just rinse off.  Stubborn stains....let it sit and do one more time....cleaned my PVC fence after 2 years+ of mildew.  Large quantities are a bargain.
