I get asked a lot about a product called Plant Wash, that is supposed to protect plants from softwashing chemicals.
It is my opinion that this product is not effective in stopping plant loss from chemical exposure.
Let's all take a good look at why I feel this way, and then decide for yourself if the Plant Wash from Softwash Systems does as claimed ?
Here we are, way back in 1999, asking this questionhttp://www.madsci.org/posts/archives...0591.Bt.q.html
And, here is the answer http://www.madsci.org/posts/archives...0591.Bt.r.html
The answer then was NO, and the answer now is still NO!
If you think you can simply spray some fertilizer on plants to "provide an additional level of protection" from the SH, you need your head examined.
The best way to protect plants from run off, is to stop the run off from hitting them in the first place (tarps)
The second best way to protect plants is with plenty of water, before, during, and after the roof cleaning.
Dilution is the solution, to pollution.
To the uneducated and inexperienced, spraying the plants with an acidic fertlizer "sounds good", because SH is very Alkaline, and it "stands to reason" the acidic fertlizer "will neutralize" the roof cleaning chemical, maybe render it more harmless ?
But, this is not how it works, in the real world!
Maybe in a labratory situation, where you know the EXACT strength of the run off, you could apply just the right amount of acid to get to a neutral PH (but then you still have the sodium salt to worry about).
But, in the real world, it is next to impossible to apply just the right amount of the acidic fertlizer, because of about a zillion variables we have little or no control over.
Now, if you apply too much acid fertlizer, it can and will supercharge the SH, and turn it into an oxidizer(plant killer)100 times more powerful then what you started with !!!!!
In fact, back in the old days (working outside with eye protection and respirators), we would acidify the river rock around swimming pools by first spraying it with muriatic acid, and then hit it with a 50/50 SH/Water mix.
This 2 step cleaning method is very very dangerous, (do NOT try this, you can be killed) but trust me, you have never seen even the worst looking river rock whiten up, as it does when the SH is intentionally acidified.
We also add acid to our swimming pools to INCREASE the activity of the chlorine, so tell me, WHY would you ever want to add an Acid of any kind, where SH is dripping, or has dripped ?
As for your answer to the question "Does the Plant Wash from Softwash Systems work", let's let a Softwash Systems Authorized Contractor answer that for us!
If you take the time to READ the PDF Files first paragraph, you can see that they kill plants too (by their own admissions), despite being connected with Softwash Systems, LOL
In fact, they even have a "service truck" they claim, just for replacing plants !
So everyone, now you have your answer to "Does The Plant Wash From Softwash Systems Work"
LOL, "Straight From The Horses Mouth"!
