what do we know about this stuff??? it says to rinse below 150 psi. maybe a 5850 with a fane tip or garden hose with a fan tip for broad path rinsing?
Re-New-All Roof & Deck Cleaner Concentrate This product has changed the way professional contractors clean asphalt shingles and decks. Re-New-All Roof & Deck Cleaner is a 7 to 1 concentrate that safely removes failed stains, sealants, mold and mildew from decks, docks, cedar shake shingles and fencing. When used on asphalt shingles, mold, mildew, tree sap and fungus, it can be gently sprayed away with less than 150 P.S.I. Re-New-All Roof & Deck contains no acids, solvents, chlorine, phosphates or peroxides and is biodegradable. It will not kill grass or shrubs.
Ha,Ha,...nice Rodney,...about this product though,..I did a quick search and didn't really find anything on it,...do you have a link or website?
With the specks in your post,..it's probably percarbonate or maybe copper sulphate,..but I don't really know what it is,..or if it works.
But,..by the description I'd say it doesn't work effectively,..shouldn't have to do anything more than rain water down on the roof when rinsing,..150 psi alone tells me the product is probably not good at killing the disease and making it disappear.
But see if you can find some more info.
By the way SH won't kill grass or shrubs neither,....when used properly. And I want a product that KILLS.

Then it doesn't work.
Even Sodium Percarbonate is a peroxide.
It may be Potassium metabisulfate based but I doubt that considering its expense.
The only thing not on the list is oxidizers in general. Which Chlorine and peroxides are... but others exist.

If it is sodium hydroxide I strongly recommend it for bare concrete, but NOT for shingles!
