A respected, reputable, nationwide franchise, Rex?
How about STOP and ServiceMaster to begin with? Servpro had been servicing this medical building. At least in my experience, as organizations they all enjoy a good reputation.
Ron, okay, CRI developed a method to measure "clean" for the purposes of its SOA program. Dare I say Rug Doctor?
My point is, while you may insist there's a good way to measure clean, NOBODY does. Clean is an opinion. Even as "professionals," it's all in how it LOOKS.
Ever walk a customer from one side to another while explaining how the olefin carpet you just cleaned still "looks" dirty?
Until an empirical method exists that everyone can use, consumers buy an individual's opinion of clean. In the case of a concerned professional as yourself, that's good enough. When it comes to debating the true, long-term efficacy of competing methods I'd like something more substantial than biased, individual opinions.
Enapsulation isn't the end-all and be-all of cleaning. I don't think the majority of users represent it as such. But, one of it's lingering benefits is simply that it helps prevent resoiling.
Encapsulation products work by covering the yarns and drying, encapsulating both soils AND yarns. The dried residue shards, with the soils remaining inside. Vacuuming removes the dried shards along with the encapsulated residues. Any encapsulant that remains helps to form a protective cocoon around the fiber. Soils stick to the encapsulant, not the fiber. Wet soils liquefy the dried encapsulant. When it dries at least some of the wet soil has been encapsulated. Encapsulants have been referred to as a poor man's protectant.
I never heard the dirty underwear analogy before. Interesting. I'm curious what would happen if someone pulled some wall-to-wall, tossed it into a huge top loader and ran it through the wash cycle. I bet the results would be at least disastrous. Kinda like the comparison of stripping and waxing a carpet.
After all these years we still can't come up with a good analogy to explain why a technology that's proven to work fine really can't be.
Am I the only one who's a wee bit puzzled why so many folks are anxious to analogize away the success of encap, OP, bonnet and other low-moisture methods while ignoring those cute little grocery store extractors? LOL
