Concrete & Driveway Pressure Washer Concentrate

Works in my pressure washer , hard to find in stores

I guess that it was too much to expect that a cleaner without chlorine bleach would work easily. I used my pressure washer as directed, and none of the dirt on the gutters came off. On the vinyl siding, the algae got slightly lighter. When wet, you could still feel the sliminess. I tried another area, spraying on the soap, allowing it to sit, and then scrubbing it with a brush. My gutters and siding were much cleaner. However, this was way more work than it should have been. This wasn't a light scrubbing that it needed. My recommendation is that you save your money and try a different product.

Important: Not the Same as Krud Kutter — Use with Caution This cleaner may look like a general-purpose house wash, but it contains sodium hydroxide (lye) — a strong, caustic chemical that can cause serious harm if not handled properly. There were no clear warnings on the bottle I received, which is concerning. If you're expecting a mild siding cleaner, know that this formula is much stronger and can damage plants, paint, and skin if used without gloves and goggles. Be sure to label the container clearly and store it safely. It worked well on concrete, but it’s not what I expected and not appropriate for all surfaces.

This stuff is useless!
