I have a spare refrigerator in my garage that I use as my fermentation\bottle conditioning chamber. It is an over\under (fridge\freezer) model that has a STC-1000 temp controller on it. I only use the fridge part of the unit for my ferm chamber and dont use the freezer part at all. I have been using it since May of this year and I have noticed there is an accumulation of water in the bottom of freezer compartment which is contributing to mold beginning to appear on the inside of the freezer.
Should I be concerned about this? Should I mix up some bleach solution to spray it down and clean it? how do i keep this from happening?
