Not a "fun" thing to watch, but few very important things are.
It is important to understand why some of your customers are opting out of having protector applied. They may not tell you why, but often this is the reason.
The trend toward cleaning customers forgoing protective treatments varies by region of the country, and more specifically the worldview of the customer.
I'm finding that cleaners are becoming more aware of this issue, even ahead of their customers. I have a customer in Montana and one in Maryland who went PFAS free with their protectors without customer demand.
In other areas, designers are becoming more aware of the issue, and those selling protection through their customer base are needing to move to PFAS free products.
I am also saddened when I see PFAS products still being sold in, or shipped into, states that have forbidden their use in those states.
