Sometimes in a home people do not pull out their refrigerator and clean behind it. This is common for people not to do. Refrigerators have fans and motors in them that circulate air around. This particular fridge was slid into a small pocket surrounded by cabinets. When SERVPRO of Brandywine/Wilmington was on site to clean the home we found a lot of dirt on the one side of the refrigerator upon pulling it away from the wall. We spent a lot of time cleaning the unit both inside as well as outside to ensure it looked and smelled amazing.
