Greetings,
Does anyone have knowledge of what materials or processes, aside from H2O2 vapor, might change an H2O2 exposure indicator from green to yellow? There have been a few Tyvek pouches with built-in peroxide indicators that have turned yellow without being exposed to H2O2 vapor.
Would any common cleaning/wipe-down agents cause the change and which might be the culprit? Sun/UV/Heat/Gamma?
Note that these aren't being used for H2O2 sterilization, they are COTS pouches that happen to include that indicator.
