Has anybody ever used powdered pool shock to make up roof wash? A 1 pound bag is like $3.00. If you've used it how much goes into a 80 gallon batch?

It's calcium hypochlorite, not sodium hypochlorite. It doesn't clean as well and leaves a white film on everything.
It doesn't work.

its the same snake oil that AC was selling.

Ask Doug Rucker about his mess!

We have been cleaning roofs in tampa (http://www.showmelocal.com/profile.aspx?bid=4955) for many years. We tried powdered pool shock w/o success.
It leaves a nasty white film (scale) on things that will take acid and pressure cleaning to remove.

Thanks for the info Doug and Russ, We were looking at ordering a bunch of it. Did anyone try mixing it in warm dihydrogen monoxide first?

Do you have a formula matt?

Diesle fuel with an ignition source for heat to alter the temperature of the rest of the ingredients. Then (you can get these at select chemical companies) add one part oxygen and two parts hydrogen in equal amounts up to a total of 50 gallons. If you need more base solution to mix up the powder, I would suggest repeating the process.

hahaha.. be careful with that dihydro, Matt. Its only safe between a narrow band of temperatures.

It MAY be possible to get the calcium hypochlorite to work, if the scale problem can be solved. It might be worth some more development work. The stuff sure is easy to carry around with you, and easy to get. Perhaps if followed with a mild acid/water rinse, it can be used successfully ?
Calcium Hypochlorite has the advantage it has no Sodium (salt) and is easier on plants.

They say it can work, if they get it the guys will love it for sure.

Be carefull when mixing that stuff up. Use a non-sparking, not-electrical stirring tool. Hydrogen is explosive and oxygen is an accelerant. Then when the stuff is mixed, caution is still needed. Dihydrogen monoxide will dissolve steel!

Doug says they have been able to augment the regular roof cleaning mix with it successfully, before the scale forms. I suggest those who want to make a powdered bleach product commercially might want to look into chlorinated TSP as a possible ingredient.
This is basically calcium hypochlorite, with a TSP overlay. My health has not been very good lately, so I haven't tried it yet.
But the added TSP in theory will make the calcium hypochlorite clean more better, possibly allowing less total concentration for the bleach powder, less chance of scale formation.

You know Ron, here in Florida, SH is plentiful, and we take it for granted. But many don't realize our roof cleaning brothers outside of Florida do not have a SH supply station on every corner. I predict that whoever solves the riddle of the bleach powder will be financially rewarded. That is, until someone copies him, LOL

I haven't used the augment method, but I have talked to guys that have and said it works great. Just seems like an added step to me that is not needed. Thats the other thing I didnt like about the Powder, is all the work it takes to keep it suspended.

It still leaves scale Matt, we never use it for roof cleaning in tampa

It's got Calcium in it, therefore your going to the haze, or (scale).

You can mix it in warm cat piss if you want Matt. The problem is not getting it to dissolve in water. The problem is what happens when it dries on your customers roof(comes out of solution)
This "product" was introduced to the roof cleaning industry, with terrible results, on my forum, and not by me!
I trusted this person, and never in my wildest dreams considered they merely just packaged up regular old Calcium Hypochlorite, and went to market with it.
I honestly believed they had discovered a scale inhibitor to make it work, at least.
Several times, myself and other RCIA Members asked for a sample, and never received it.
The next thing I knew, it was sold to several unsuspecting distributors, who sold it to roof cleaners everywhere.
Doug Rucker went public (thank you Doug), and did us all a great service, by warning everyone about this crap.

I understand the same company who introduced this crap is now suggesting what they call "augmentation" (adding it to) your roof cleaning mix with this stuff!
There are several factors effecting the scale formation of Calcium Hypochlorite when it comes out of solution.
To me, it just isn't worth taking the chance of a major disaster with this product anywhere near your tank.
As Doug Rucker showed us, the results of using this stuff are not pretty, and hard to remove.

Calcium Hypochlorite does have some interesting properties vs Sodium Hypochlorite. IF the problems of using it can be solved, it will greatly cut down on plant damage because unlike SH, it breaks down to harmless calcium!

But until more research and testing have been done, the RCIA does not suggest it's use.
