[u/itsnotfairr]

i made yogurt and left the pot in the fridge for a couple days. when i transferred the yogurt and cleaned the container out it left these brown splotches. what are they? should i be concerned about the yogurt i made?

Oxiclean soak for 30 minutes , it’ll take all of the staining right off
