We don't usually cook big meals in a microwave, but even the simple act of heating something can leave smells, stains and a sticky mess, not to mention the dust that can gather around the outside. For me all it took was a burnt bag of popcorn and re-heating coffee to turn a brand new shiny microwave into a grimy, smelly mess. The secret to keeping a clean microwave is regular maintenance.What You Need?You can clean a microwave with the everyday cleaning products you already have in your house: All-purpose cleaner Baking soda Dish soap Vinegar (white or apple cider) No-scratch sponge or microfiber absorbent clothMake sure you do not use bleach because it can deteriorate the plastic interior and damage the appliance in the long run.Cleaning The Insides Of A MicrowaveStep 1 Combine 1 cup water and lemon juice in a microwave-safe bowl. Or, if you have white or apple cider vinegar on hand, combine a few tablespoons and 1 cup water in a microwave-safe bowl.Step 2 Place the bowl in the microwave and turn it on high power for 8-10 until the mixture boils and the window steams up.Step 3 Let it cool for 5 minutes before opening the door, then remove the bowl and wipe the inside clean with a sponge.Step 4 Wash the turntable by hand with soapy water and a non-scratch scrub sponge.Cleaning Microwave DoorsStep 1 Dampen a sponge or cloth with water mixed with baking soda.Step 2 Wipe down the edges, both sides and the hinges that seal the oven.Step 3 Rinse and wipe dry the window with a 50/50 mixture of vinegar and water.Step 4 For thick grease build-up and splatters, wipe your microwave door with an all-purpose cleaner or a frothy mix of dish soap and water.Getting Rid Of Bad OdourStep 1 Clean any leftover residueStep 2 Air out the oven by leaving the door openStep 3 Place a bowl of baking soda inside with the door closed to absorb smells.Step 4 Place an odour-absorbing gel inside until you run it again.Additional Tips To Keep In Mind Apply the cleaner with a cloth or sponge. Scrub with a non-scratch pad. Do not spray directly on electronic controls panels. Always apply the cleaner to a cloth first, then wipe the controls.
