That’s why I always keep a bottle of WD-40 handy to remove the dust that builds up inside. Take good care of your unit and it will take good care of you. No one wants to spend a hot summer with a broken air conditioner (or worse, a burnt one). Learn from my mistakes.
Again, we have to thank WD-40 for saving the day. Spray some of it on the mold, wait a few minutes and wipe it clean. It’s incredible how effective it can be at so many things, and keeping your refrigerator clean and working is a big help.
