I just got some samples of a Bleach Masking Agent from a small company no one has ever heard of.
Maybe it will work, and be cost effective ?
I can mask the smell, it just adds cost.
If this turns out to be another dead end, I think downstream injection is THE answer.
With Downstream Injection, we need not be concerned about chlorine stability or compatibility.
We can use cheap fragrances and surfactants w/o any fear of weakening our mix !
It is very easy to rig up a downstream injection system.
And some roof cleaning skids, like the one AC sells, already have it designed right into them!
I have a student I taught using a downstream injection system to mix soaps and fragrances into his pump.
He uses Mexican powdered laundry detergent from WalMart that is dirt cheap as his surfactant, and an really powerful synthetic fragrance that is NOT chlorine compatable.
With the downstream injection system, he almost gets a fragrant roof cleaning shaving cream style foam that sticks like glue, and smells awesome.
It is my belief that a downstream injection system is THE way to go, if you seek the ultimate roof cleaning and softwash set up.
The commercial examples of these roof cleaning and softwash setups seem a little expensive, but consider this ?
They allow the use of far cheaper non chlorine compatible surfactants and fragrances!
Expensive chlorine stable surfactants and fragrances are no longer needed.
Bob from Ugly Shingles has posted the way to easily build a downstream injection system at RCIA, for those who want to do it themselves.
And, AC of Softwash Systems and others make turn key downstream injection roof cleaning skids for those who want a tested and proven system they can just buy.
