I'm under the impression That HOST would not solve the problem caused by the owner when they use water and vinegar to clean the pet stain.
You are correct sir.
So maybe I shouldn't touch it any further? what's your thoughts @The Great Oz
Do it if you want and if the customer retains ownership of the problem, and if you aren't worried if they're happy or will pay when you're done. I have no way to know if our techs ran into this all of the time and were able to fix it most of the time.
Have you received several callbacks from customers who have this carpet that your techs have HWE on and didn't know it was Earthweave?
If we run into a new product that has issues before other people do, we have to figure it out or own it.
A nearby new install customer pressed us to replace as the problem got worse as the tech worked on it. That's when I got involved.
Greenhome wasn't any help with that customer, and since it was a small condo we paid to replace. The next color issue that came up was an install by a small, friendly-to-us company. Their installer gave us some insight into issues they had seen and came with me to look at the carpet. The entire house was Earthweave, with the problem only in one bedroom. We couldn't fix it, and it got worse. They replaced the carpet in that bedroom.
Shortly following was the water damage. No color change problem with that one, just the extreme shrinkage. Maybe all of them were reactions to something applied, but we cleaned a lot of wool without seeing these issues.
A piece of the carpet we paid for went into our training program, I gave a (useless) education to the Greenworks manager and let him know we'd be referring any future problems with the product back to them.
