Occasionally cleaning household appliances like stoves and refrigerators may seem obvious, but what about equipment that does the cleaning, like the dishwasher and washing machine? Give these often overlooked appliances a deep clean with the following tips before the holidays have them working overtime.

Unclog the dishwasher. The cleaner the dishwasher, the cleaner your dishes will turn out after going through a wash cycle. Take a moment to clean the dishwasher's filter, usually located on the inside bottom of the machine. This detachable filter becomes clogged with food and debris over time, so empty it out regularly to keep it working efficiently.

De-gunk your garbage disposal. Use a natural abrasive combo of ice and salt to loosen grime from the blades. Though it will be loud, run the disposal until the ice is gone. When finished, you can grind up a lemon or lime wedge to deodorize the drain.

Give your washing machine a wash. Hosting out-of-towners during the holiday season? Avoid musty bedding and towels by sanitizing the machine and removing mildew buildup every few months. To do this, run a hot wash cycle without a load and add one cup of bleach to the soap dispenser or directly into the machine.

Give your vacuum more power. Increased foot traffic could have this tool working harder over the holidays. Keep your vacuum maintained with simple fixes like unclogging hoses, cleaning the rotating brush and replacing the filter.
