Wash everything down with some hot oxyclean solution. I do that and then spray everything down with Star San. Mold formation in a high humidity location is almost inevitable. Keeping everything as clean and dry as possible is the best defense. Excessive condensation accumulation is an indication of an air leak somewhere. Check your gaskets and the integrity of the collar (if you have one installed). Damp Rid can go a long way to mitigate condensation problems.
thanks for the replys
there is only a little bit of moisture on the inside sides of the keezer the seal is in good shape so dont think thats a problem
I am going to pick up somr damp rid today and give that a try
+1 on the Damp Rid, I had a bad problem with humidty build up in my keezer. But I now use 2 of the small containers of damp rid and my keezer is nice and dry. Also like was said above check your seals, even though they may look good you may still be letting outside air in.
