Hi Randy
When I tried to get some of their product, I couldn't get any. They wouldn't deal direct, there are no local distributors, and being blunt, they basically told me I was SOL!
Allegedly they have an excellent grout film remover, but unfortunately, I couldn't try it. As for me, if TYW can't help me, I'm sticking to Prosoco. Their product catalog is about 1" thick, and not confusing (to me).
