Help! I just noticed there is mildew/ mold spots along the back wall, back corners and under the rear ph windows. I've always made sure (or at least thought I did) that their is no condensation left when I close it. I've tried the half alcohol half h2o solution as well as a gentle natural mold and mildew remover with no luck. There are no leaks in the ph and the spots are strictly inside. Any suggestions on how to get my PH looking like new again?
