Yes, I am writing this to avoid writing about the worst piece of Illinois energy legislation in my lifetime. But it is true that this is a great way to save energy and extend the life of your equipment. In addition the site has other useful cleaning tips.
The Worst Cleaning Jobs Made Easy
Dirty Job No. 7: Cleaning Behind and Under the Refrigerator
Time it takes: 20 to 30 minutes.
Why it matters: Lots of dust on the coils can cause a refrigerator to run inefficiently. And dust under the refrigerator can mix with moisture from the air to gum up the finish on your floor.
Step 1: Pull out the refrigerator by grasping both sides and gently wiggling it toward you; some are on wheels, so this may be easier than you think. When you can, reach behind and pull the plug (your food will survive for the short time it takes to clean). If you have an ice maker, shut off the water supply first, just in case the hose comes loose.
Step 2: To dislodge dust around the condenser coils (the wriggly apparatus in back), use a long, thin tool known as a refrigerator-coil brush (Rubbermaid, $9, acehardware.com), then gently vacuum with a brush attachment. Some refrigerators have their condenser coils behind a removable grille in the front. If yours does, snap off or unscrew the grille and clean the coils, as above.
