Green Wash

Doug R · Guest

Jeff, yes I did. IMO it worked great, just the after haze was the problem. And I am not sure that it may have not been some of my fault in mixing it to strong or something. It was the first time I ever used it. The problem with dealing with the after haze is having to use acid to get rid of it. Not something I want to do on every roof I clean. But I am all for continuing the efforts of trying to get a powdered bleach. In fact I am not sure you can get the Green Wash by the gallon anywhere, but to assist you in your testing and show my support I'd be happy to send you a gallon of mine at no charge. Just get me your address by either email or PM and I'll get it out Monday. dougrucker21@gmail.com

Thanks Doug, Ill send you a 5 gallon to break up. Were just not set up to do that right now ourselves. Call and run it through Sunbrite Supply and I will credit them appropriately.

Doug,

I just sent Mary at Sunbrite an e-mail she will be awaiting your call.

Jeff,

Thanks for the oportunity.

Thanks Doug,.I am willing to pay you for it,..But yes,..either way,...I'd appreciate the gallon so I can try it out. As I said performance is first,..the white hazing you experienced would have been there even if mixed light, so it waqsn't your fault on the mixing ratio..but iissues of the hazing could be minimized alot with some adjustment and understanding of the mix and how it's applied,..which I believe you have alot better understanding as of now,Ha,Ha,...There are probably things you'd do different now,..even after only one use.

@AC- Thanks for working with Doug to ship some out for testing purposes.
I always wanted the Bleach Wash to work,..even though it may not have seemed that way,..I was hoping I was wrong and was gonna have to eat crow.
But I've fooled with CH years ago and a few times even after switching to liquid,.. so I understand the advantage of a powder over a liquid,..and the longevity of clean it gives,..yes I'm interested in working with the Green Wash and see what results I can get from it and maybe tweak it into an acceptable method for at least a few of us,..and maybe a backup for those with DOT concerns. If the Green Wash does make the CH work,..then the wheels fell off this project way to soon,..if the hazing was the main downfall.

Considering the Green Wash does boost it to liquid hypo results,..then the hazing isn't a concern of mine. Heck, I use to mix CH up by the 55 gallon drum and use it as my house wash base,..just as I use liquid hypo now,Ha,Ha,...

CH at least has possibilities for a powdered cleaner,..where as sodium percarbonate hasn't a chance.

You know what ? I have been doing research on Chlorinated TSP, and it is used routinely in Breweries. Yes, it does take a slight acid wash to eliminate the film, but consider this ?

If the bleach powder was used to clean roofs, followed by a SLIGHT Acid rinse, it can sort of be marketed as an ECO Friendly roof cleaning system, because the run off is nearly totally Neutralized. Unlike SHC, Cal Hypo has no SALT run off, only harmless calcium !

I too have experimented with Cal Hypo, and found that TSP added to it made it clean better.

IF I were AC, here is what I would do biggrin I would re configue my Bleach Powder to include some TSP, and possibly some Baking or Washing Soda, as the breweries do when using Chlorinated TSP. Then, I would configure the SoftWash Systems Skid to use an acid rinse.

I think this will be powerful, because they could offer a truly Eco Friendly house and roof washing system.

I think it will sell, because look at all the heroic measures some contractors take to use alternative methods to SHC cleaning methods.

Of course, us SHC Cleaners could also use an acid neutralizing rinse, but we would be doomed because SHC still degrades to Salt, and Calcium Hypochlorite degrades to plant harmless Calcium.

You know Jeff, a rinse afterwards is not all that bad, as long as you have a high flow kick ass pump to rinse with. Since the SoftWash Systems rinse pump will NEVER see Chlorine, there are very low cost acid resistant pumps that can be used.

I can see the SoftWash Systems Sales Video now, where AC takes a soil sample before and after the cleaning, and shows NO Change in Soil PH

Then, he does a cleaning with SH, and shows the salt and PH increase in the soil.

That's some powerful Kool Aid Jeff, because it is true biggrin

"Mr Customer, the SoftWash System will not alter Soil PH, or effect plants, and we guarantee it"

Hey Chris,..I think this is at least feasible,...I will be trying the most basic ideas first,.. Green Wash/CH,.. and then maybe try the addition of others such as TSP, as you suggest.
Rinsing the white film isn't necessary anyhow,..if done properly and applied with control,..the mess can be minimized a great deal,..and spraying lots of water is an essential key,...ESPECIALLY with CH. But it can be done,..and with repetitve use I think anyone could get the hang of using it.

I hope the Green Wash gives it the punch needed,..the hazing will be a non issue for anyone who wants to learn the proper method,...considering the idea of using a powder,..I think it will be worth a learning curve.

If the Green Wash don't do it, then we must look at ways to vastly increase dwell time, like foam or a Gel. I still think the acid rinse may be not such a big deal, and it has advantages sales wise.

In my experiments years ago with Cal Hypo, the addition of TSP made a considerable difference. Think about it, Chlorinated TSP is so proven effective, there is a commercial version of it !

IMHO, we need to look at what people are already doing to and with Chlorinated TSP Jeff, because the same will apply to us.

This info posted below also applies to Calcium Hypochlorite. It is the Hypochlorite ION that does the roof cleaning, and it's formation is higher at higher PH Levels. TSP in a 1 percent solution is at PH 12 ! There is NO Question that adding it to the bleach powder, and/or something else to raise the PH of a Calcium Hypochlorite/Water solution will increase the formation of the Hypochlorite ION, and improve cleaning performance.

Mechanisms of actions of sodium hypochlorite in cleaning and disinfection processes.

Abstract

Sodium hypochlorite (NaOCl) is the most widely used disinfectant in the food industry despite the increasing availability of other disinfectants. Sodium hypochlorite fulfills many requirements as the ideal disinfectant and furthermore it has an excellent cleaning action. The effectiveness of sodium hypochlorite in the cleaning and disinfection processes depends on the concentration of available chlorine and the pH of the solution. Hypochlorous acid (HOCl) is a weak acid and dissociates to the hypochlorite ion (-OCl) and proton (H+) depending on the solution pH. It is generally believed that HOCl is the active species in the germicidal action, whereas the concentration of -OCl is a key factor determining the cleaning efficiency. This implies that the optimal pH region of the germicidal activity of sodium hypochlorite differs from that of its cleaning activity. This paper describes the theory and practice of the cleaning and disinfecting operations based on the use of sodium hypochlorite solution.

The tests I did with Green wash, were adding it to SH and as I said, it worked just fine, but did not increase cling much, if any that I could tell. Is there any reason why Ammonyx Lo could not be incorporated in the mix as a thickener?
If I understand this thread properly, and Doug is going to ship out 5 individual gallons of Green Wash for testing. I would be interested in testing it with the Bleach Powder, instead of with SH, as I did before.
If you are sending some out for testing, I'd be glad to give it a try!

? I didn't see any text?

Yes Chuck,.the more feedback we can get the better. I hope you and others can get their hands on some 1 gallon quantities.

I have some 73% CH I will be trying with the Green Wash that Doug has been generous enough to send me,..I think 73% is about as high a percentage as you can get CH?? Years ago when I was using it regularly I think it was 62%,..so maybe this higher percentage will help? We shall see.
