Take a peek inside your washing machine and you may be surprised at your finding. Yes, that's grime! But where did it come from? You'd think that since your washer is constantly cycling water and cleaning your laundry that it would be self-cleaning, but not so. Just like you get soap scum in the bathtub, you get scum from your laundry detergent in your washing machine. BUT, I am going to bless your bones by letting you in on a little secret on how to get rid of that grime quickly and with little effort:
Pour 2 cups of white vinegar into washer, start your washer until it's filled with water and then stop it and let vinegar sit in the water for an hour. After an hour, allow water to finish cycling through and then wipe with a sponge and VOILA! looks brand new.
