W M BARR FG581 128OZ Siding/House Wash

I've become a huge fan of Mold Armor house wash (same as their deck/fence wash). The stuff "just works" like no other. However, the only version I could ever find is the hose-end thing (and the refill for the hose-end bottle). I needed to reach higher than the hose-end sprayer could reach, which I was planning to do with a few special attachments on my pressure washer. I could not find Mold Armor for pressure washers anywhere and I could not figure out why (still don't know why it's so difficult). After searching for a while, I finally found the pressure washer version here and on a couple other sites. With our Prime membership, this ended up being the best deal for us. It worked like a charm - as it always does.

I simply insert low pressure nozzle feed tube directly into jug, spray on, let work and then rinse off with higher pressure nozzle. Probably has a bleach base so wondering if a diy bleach solution would do just as well less expensively.

I used this with my gas power washer on my vinyl siding. I used the detergent tube directly in the product to spray it on then after 10 minutes rinsed it off with the yellow tip. There was a lot of green on the back of the house and this took it off completely.

Used as instructed using the feed line for my pressure washer. If you have a tank,pour it in as is. Melted the mold right off of my vinyl siding after soaking a few minutes then rinsed. It does contain bleach. You can smell it and I wrecked a shirt,but got the job done. I’ll use it again if needed. Good stuff.

A gallon did the job of cleaning my whole house

We got quotes for cleaning the house siding - $700. We bought 2-3 bottles of this stuff and were able to do it ourselves. It looks great. The $700 guys couldn't have done any better.

No

It cleans thoroughly.
