no ive never tried and to be honest, you know your custies a lot better than i do, just given you some of my knowledge on how hard it is to find someone that needs there carpets cleaned, like joe said with his 5 year carpet, my wife had a call today today for a wine stain, "its been down 9 years and never needed cleaning and its worn well, i only want the wine stain out, noy a full clean"
why don't you survey 100 of your best custies and see what they think before you make any rash decisions?
