A web site "involved" with silver safety has popped up
on this forum that some CS people may find misleading.

The provider of the "safety" site is also flogging their ionic
silver product at the expense of colloidal silver.

 Without listing the many misstatements of fact in their
sales pitch, such as "all CS products are ionic" or "colloidal
silver is good but very limited" or "only factors that matter
are carrier agents" like, for instance, insoluble silver oxide, or
questioning the veracity of microscopic photos showing silver
nanoparticles actually killing viruses, well, let's not do that.

Suffice to say, nothing kills microbes better than CS.
