Roof Cleaning Using Fresh Wash

Roof Cleaning

Here are a couple of picture from a Roof Cleaning in Albany NY using Fresh Wash. We used about 30 gallons of solution to clean both sides of the roof

Thats a great before and after Clark.

What was your mix ratio (water/bleach/FreshWash)?

4

15 gals 12.5 sh, 30 gals water, and 30 ozs Fresh Wash. The Fresh Wash did a good job of masking the sh. Also as a surfactant. Next roof I’m going to go up to 1oz Fresh Wash per gal of solution to increase the cling.

I’m very curious to see how low we can go on the sodium hypochlorite when using Fresh Wash in the mix.
I have heard that it really works synergistically with bleach.

6

Next roof I do I will cut back the sh to around 20% to see how it does.

I will, too, and we’ll compare notes.

[LEFT][COLOR=#1A1A1A][FONT=lucida grande]Lowest I have been able to go is 12 gallons 10%SH, 53 Gallons Water and 48 oz’s Fresh Wash. That was for a moderately stained roof. For heavy stained I go with 16/49/48.[/FONT][/COLOR][/LEFT]

Thanks Doug on a percentage basis the 12 gal mix is 18% sh on the 16 gal mix it’s 25% sh. Fresh Wash is .75 ounces per gal

The roof I posted the pictures of I used 33% sh and .66 ozs per gal Fresh Wash.

Thanks Clark…

Does Fresh Wash create suds? And will it keep creating suds, let’s say in the next time it rains?

Did a roof cleaning today using a 25% mix. It worked very good. Upped the Fresh wash to .75 ounce per gal of mix this seems to be where the Fresh Wash needs to be.
