What Customers Are Saying

Customers praise the product's effectiveness at eliminating algae, mold, and moss without scrubbing, with many noting impressive results on driveways, patios, and siding. The hose attachment and three-position nozzle make application straightforward and convenient. Most appreciate that it works over time rather than instantly, though some report incomplete removal requiring follow-up pressure washing. A few found it ineffective on certain surfaces or experienced no results. Overall, reviewers consider it a worthwhile solution for those willing to wait for biocidal action to take effect.

Best exterior House Cleaner

Would Not Recommend

This is the best house cleaner! So easy spray on with a garden sprayer and let it do it's work. You won't see results right away but over time you will notice gutters, siding facia are clean. First product I used where the green mold didn't come back!

This works

I wasn’t sure how quickly this product would work. I had algae/mold on the side of my house. I sprayed the house and in a couple days you couldn’t even see it. I highly recommend this product for how well it works!

I was just gonna ask the same question about, it says Bleach free but contains sodium hypochlorite-SAME. Concentration varies

Is it pet safe?

Description says "Bleach and phosphate free" but the active ingredient is Sodium Hypochlorite (bleach. Please clarify.

How many sq ft dose a gallon cover

Has anyone had luck with this killing Moss on a roof in a damp area
