1. Deep cleaning. Do you feel like your clothes are not coming out as clean as they should? Or do you detect an odor inside your washing machine? Then it's time for a deep clean. I like to use The Laundress Machine Cleaner once a month to clean out my washer — and I've noticed it cleans better when I do. You'll want to run an empty cycle on hot wash with your machine cleaner — or simply laundry detergent. You can make your own DIY washing-machine cleaner. If you feel like your washing machine needs sanitizing, make a solution of 3/4 cup of bleach and 1 tablespoon of powdered laundry detergent. Let the solution run through a soak cycle of your machine, and then run a rinse cycle to remove the bleach and clear it out.
