Hi Larry,
You are right, we have not tested Rhino-Shield against ALL carpet protectors sold in the world; therefore our statement was too presumptuous for those that take everything completely literal.
We certainly do not want you to have a problem so we changed our statement to read: "Out performs, in every way, all of the "Big Name" protectants that claim protection against acid dyes." BTW, we mean that statement in the most literal sense.
Thanks,
Steve
P.S. Larry, you have many great products and since my old carpet cleaning company used many of them over the years, if our product line won't fill a particular need of one of our customers I have no problem recommending your company. However, I certainly don't agree with every claim you make, but if I develop a PROBLEM about one, I promise to give you a call and let you know privately.
