john,
i'm very much aware that encap shampoo's have been around for eons. i know, i've used them, however, they were of such poor quality, and promoted such rapid resoiling, via the residue they left behind, i chose not to mention it here in my initial response. they paled in comparison to todays products cause the old encap products didnt encap squat!
i did also omit my initial cleaning step with orientals, and thats back dusting using compressed air. i did that under my carport at the time over an A frame stand i built just for the rugs.
there was a time in this business when doing orientals was an extremely profitable endeavor, the same way upholstery cleaning was. but due to the many so called experts in the field, i no longer persue them. these questionable at best so called experts, dont know thier ass from a hole in the ground, and lil by lil, they drove the prices down so much, i found it no longer worth my time.
but thats just me i guess.
some folks like to work for peanuts, so god bless em
