Bright green, red or other color goes away when the active antiseptic evaporates.

When you're out in public, this would go along with wearing a mask. You and others would know that your hands are loaded virus killing machines as long as the coloring remains.

Polychlorinated biphenyl https://en.wikipedi...hlorinated_biphenyl
Very persistent; not very nice at all. Simple chlorophenols are a bit safer. [8th of 7, Apr 29 2020]

       The alcohol-based ones are inactive as soon as they're dry. There's no residual effect.   

       Surfaces are disinfected, but are immediately susceptible to recontamination.

       It would have to be something whose sanitizing effect lasts longer than alcohol and has indicating color linked to it.

       Chlorophenols, then, although you risk dermatitis and other undesirable effects from long-term exposure.

       90 days? What's it contain? Polonium?   

       Thanks for the link though.

       Good job we're here, then.   

       Chlorophenols are very persistent (vidè problems with PCBs) but the problem would be unintentional mechanical removal on the very surfaces where it's most needed.
