I really am not well read up on this, but I wonder if that is the same kind of silver? The nanoparticles in these cloths are said to be activated after the cloth has been used (so the silver doesn't rub off on the bulldog belly), whereas products with colloidal silver actually go onto or into the skin. Anyway, there is an overall problem with those products that kill off all bacteria as that may lead to antibiotics-resistent bacteria.
Any time I see something for sale that abundantly touts, "ENVIRO" green, good for the environment, saves money, recycle, not wasteful, helps trees grow big and strong, won't displace the speckled newt or the spotted owl...and charges ridiculously high prices for it...hmmm...
I guess I'm just the suspicious type...here's what I found...
"Norwex has developed a unique technology that combines an antibacterial silver-based agent with our microfiber. The antibacterial agent is embedded inside the tiny microfiber. The agent is solely designed to inhibit bacterial odor, mold, and/or mildew growth within the cloth."
and
"The surfaces cleaned correctly with Norwex are removed of 99% of bacteria thanks to the construction of our high quality microfiber, not the silver."
"Dry completely. Use Norwex Ultra Power Plus Laundry Detergent for best results. For deep, stubborn stains or odors, microfiber can be
boiled for 10 minutes to allow fibers to swell and release the debris."
"Use wet or dry to clean everything with just water!"
WTH?!
Mind you..."bacteria odor" is mentioned, not bacteria. I'm not exactly sure what bacteria smells like...probably not so good, but removal of "bacteria odor" is NOT the same as removal of bacteria. This whole pitch seems like slight of hand and is intentionally laced with ambiguity. This sounds like a good(not great) technique for extracting money from one's wallet.
The microfiber towels are extremely expensive and look exactly like the ones that I use to clean my cars and wash windows. I've never had a problem with "bacteria odor" on my cheap microfiber because I wash them on the high temp setting of my LG washer and I also use soap and a splash of bleach...and that's been known to kill bacteria.
Not buying it at all...literally.
I don't mean to offend anyone here but I'm the skeptical type and I see a very over-priced product that has AMWAY written all over it.
