Zep House and Siding Pressure Wash Cleaner Concentrate 128 Ounce ZUVWS

This Zep House & Siding Wash is absolutely fantastic. I used it to tackle a year's worth of built-up dirt, pollen, and green algae on my siding, and it made the job incredibly easy. It practically melts the grime away on contact. I applied it using a pressure washer injector downstream, let it dwell for a few minutes, and rinsed it off. The difference is night and day—the siding looks brand new and has a beautiful, clean shine. No intense scrubbing was required at all. For a 128oz bottle, the value is unbeatable. I will definitely be using this every spring!

Great stuff! Like the other Products marketed by this company, it works as advertised, is economical, and decently priced!

I’ve tried a few different cleaners for pressure washing, and this one has been the best so far. It lifted off mildew and dirt that other products barely touched. Didn’t leave any weird residue, and the smell wasn’t overpowering. If you’re dealing with weathered siding or doors, this stuff makes the job way easier. For the record this door is on a shed way in the back of my yard. And I had to buy a extra Water house to get back there. So ive neglected this door/shed for like 5 years lol This stuff works best spraying directly on a dry door. Let it set for 5 minutes and then pressure hose it off!

It removes dirt pressure washer alone will miss. Helps remove black streaks on gutters.

Works great in my foam cannon and did a good job of loosening up the dirt on the siding for the pressure washer to remove. I also used it to wash my RV AND and it came out good too.
