Chris, do your customers not mean recycled pop bottles and ketchup bottles ie plastic.
I used to retail carpets and at one time, this type of carpet was on market.
It was sold as stain proof, worked on the idea that stains wouldnt stick, as with a
ketchup bottle, once stood up all the sauce runs to bottom of pot and leaves upper
sides clean.
I actually bought one, was about an inch thick, very durable, but did have trouble removing
the odd stain.

Andrew
