Usually works well. Have a new battery powered Scott's Pump. Will see if it saves time to spread the mix around.

Eliminates green mildew FAST!
Would RecommendWorked perfectly on heavy green mildew on a pressure treated deck in just a couple days. Doesn’t completely eliminate black mold on same pressure treated wood.

Works over time!
Would RecommendProduct seems to work over the long run. I can leave it working for months and only need to refresh in about a year.

Does exactly what it says it does. Works great!
After spraying the green stuff growing on my vinyl siding with Wet and Forget, the green faded over the next three days to where it is no longer visible. And the residual spray is still on the siding preventing regrowth. Not having to wash off the siding after treating with Wet and Forget is a great time saver.

Left a residue
Would Not RecommendIt left a sticky residue all over the treated areas. I have to power wash to remove and hope it doesn't ruin my vinyl siding
Very easy to apply but not overnight results
Would RecommendVery easy to use, mixed in a 2 gallon weed sprayer and applied over my vinyl siding no scrubbing needed to remove the mildew, the only downside is it works slowly but after a few weeks it’s almost completely gone.

It will take a little bit of time to see results when using Wet & Forget, as it works with Mother Nature to clean up surfaces. Typically for moss...
