True 30 Second Cleaner

This 30 second cleaner is great on vinyl siding, as an general all purpose outdoor cleaner, no leftover residue and doesn't have a strong chemical smell like most others. Mix it in a garden sprayer and you are ready to clean.

Literally Worked In 30 Seconds!

The product worked really well. I had tried the day before I bought the product to use a power washer on my fence, which only caused damage. The 30 Seconds worked really fast. In a couple of spots, I had to soak with a little more solution, but the fence hadn't been cleaned in a few years. I would use it again. Make sure you wear a hat, gloves, mask, safety glasses and old clothes when you use it. Fumes are strong but not overpowering and outside, the wind can blow the solution into your hair, eyes and onto your skin.
