5. Wipe it down — inside and out. I've been rather neglectful of my washing machine and noticed that it's getting a sticky residue from small detergent spills. It's important to wipe down the outside of your washing machine about once a week, just as you would any other surface in your home. The best solution is a mild dishwashing liquid (which can cut grease) and water.
Don't forget the inside of your washer! You should periodically wipe down the inside drum of the machine with a damp cloth. It's easy for lint, dirt or soapy residue to build up inside.
