What Customers Are Saying

The 30 Second Outdoor Cleaner is an effective product for removing mold, mildew, and grime from various outdoor surfaces. Most customers found it worked quickly and efficiently, often requiring minimal scrubbing. However, some reported it was less effective on heavily soiled or deeply embedded stains, requiring multiple applications or additional scrubbing. A few also noted it can be harsh and may damage or discolor certain materials like painted surfaces or fabrics. Overall, it is a powerful and convenient cleaning solution, but users should follow instructions carefully and test on a small area first, especially for delicate surfaces.

Best siding cleaner there is.

Would Recommend

This is the best product out there to clean mold and mildew off of decks and siding. Do not get it on windows and let it set for more than few seconds. It will mark the glass and it is very difficult to remove.
