when was the last time you applied protector to a commercial carpet?

Let's see....the scaly outer layer of the wool fiber holds dirt but doesn't allow it to penetrate, so that it readily vacuums away...it is inherently soil retardent.

Something like that Bryan?

Wait, is that in the S-100?

I think most factory manufactured wool carpet is treated with a fluorochemical these days, even if the mills don't say so.

Methinks you misunderstood Bryan

Yeah, that was meant for Marty. Thanks for the backup.
