So I forgot to clean one of my plastic nests after moving a colony out and long story short the entrance of the nest has a few tiny brown/black stains on it. I tried scrubbing them off and nothing. Let it sit in hot soapy water for a half hour and scrubbed it after and nothing. Since it has been thoroughly cleaned and it is just discolored from what I can tell is it or could it be any threat to a colony I move in?
Also if anybody has any tips on how to get rid of stained plastic that would be nice 
Thanks!
