Summary
We were able to find a few companies in the US that manufacture antimicrobial coating for stainless steel, however, many of the results we found were outside of the US. This is why we have included one company from the UK. While each manufacturer seems to be very transparent about how they make their coating, and what tests have been performed on it, we did not find any that specify if it is completely invisible. We assume that this information must be obtained by talking to the company directly.
