Surprised that this product works on Crabgrass!

Works great on green algae on my porch. I had some left over so I spritzed a few weeds. To my surprise, it worked surprisingly great on crabgrass! I know this not its intended use, but it works for those pesky weeds in cracks. I don't like using herbicides, so I was pleasantly pleased.

Workout horse. Will buy again!

The spray was easy to use! I cleaned my carport after 18 years! The instructions were easy to understand. It cleaned away dirt, mold %26 algea quite easily. Since it was so ground in in areas of not cleaning for so long, it require some elbow work- outs. Mainly, the spray melted the dirty carport very well. Didn't see a stain.

One of the best cleaners for vinyl siding, shed, top of aluminum carport, just mix as directed and spray on, leave it. Gets surface cleaner more each day. Looks brand new. I love this product,and they also have some of showers, just spray and leave on as long as you can, then rinse off before next shower, looks like you scrubbed all day.
