What Customers Are Saying
This outdoor cleaning product effectively removes mold, mildew, dirt, and stains from various outdoor surfaces like siding, decks, and concrete. It offers powerful cleaning action that often works in 30 seconds or less, without extensive scrubbing. The product can be used safely around plants when applied as directed. However, some users noted it may require multiple applications or longer dwell times for heavily soiled areas, and the bleach-based formula can potentially discolor fabrics and damage plants if not rinsed thoroughly. Overall, this appears to be a high-performing outdoor cleaner that delivers good value when used carefully.

No easy rinse
Would Not RecommendThis product didn't proform up to its claim. I applied it as directed, but rinsing it off was a problem. After repeatedly rinsing it there was still a light residue on the surface. I would not buy it again.

House Cleaner
Would RecommendGreat cleaner for siding and gutters. I used my Petra Tools sprayer and 30 Seconds to clean the algae and pollen off the siding and gutters. Just spray it on, let it sit, and then hose it off. No need for a power washer or ladder…
