W M BARR FG581 128OZ Siding/House Wash

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.

A gallon did the job of cleaning my whole house

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.

No

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.

It cleans thoroughly.

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.

Cleaned house very well. No more green!
