Norwex cleaning products from Norway have microfiber cleaning cloth woven with silver that they profess is anti bacterial because of the silver fibers. I use them- not sure if they are killing bacteria but I trusted their claim and bought some. Something to look into?
That type of product is not intended, nor effective, at killing
bacteria it finds on the surfaces you clean. What the silver does,
however, is reduce the degree to which your used/damp cleaning cloth
becomes a bacterial nursery. Ordinary washcloths and dishtowels, used
to pick up general gunk, then stored still damp, can quickly develop
a fairly significant bacterial population right on the cloth itself.
The silver in the fabric discourages that colonization. It will also
help to keep the cloth from developing odors when not in use if it’s
put away still damp.
