Smells develop in washing machines for a whole bunch of reasons, from the buildup of excess detergent, to trapped moisture. The solution to a smelly washing machine problem is to run a cup or two of white vinegar through an empty hot water wash cycle (this is also a good time to wash a small load of cleaning rags or a mildew-y shower curtain liner). While you can use bleach for this operation, it’s not ideal because if residue lingers, it could cause damage to dark clothing. And don’t forget to wipe the gasket out with a rag dipped in white vinegar, as mildew will prosper in that dark and dank environment.
Over time, kitchen walls and cabinets (and the vent hood, oh God, that vent hood) develop a sticky patina caused by the grease and steam released when you cook. Regularly wiping vertical surfaces with a mild detergent will keep that film at bay, but once it forms you’ll need a more heavy duty cleaning product. Enter, ammonia. Ammonia is so great on grease, and a little bit goes a very long way. To use it, dilute a quarter cup in a gallon of water, don a pair of protective gloves, dip a rag or sponge in the solution and swab sticky surfaces, wiping them dry with a cloth or paper towel. If you’re looking for something a little less harsh than ammonia, Simple Green is a good choice. Always spot test first to make sure the cleaning solution won’t cause damage to the paint, finish or wallpaper.
