So you just washed your clothes and the still stink and so does the washer. Chances are it is not the detergent you are using rather it is the washer itself. So how do you clean the behemoth of an appliance? That is more simple than most people think and should be done at least monthly to keep the machine performing at its best. Here is a recipe I have found that works really well for getting the stinky smells and soap scum out of the washer.
1cups Washing soda
1/2 cup Borax
2 cups Vinegar
to make and use
First, mix the washing soda and borax in a bowl till evenly mixed. Then pour the mixture into the detergent slot. If you do not have a detergent slot, that is okay. Then pour the vinegar into the softener slot. If your washer does not have either the detergent or softener slots, that is okay. Just pour the washing soda and borax into the drum and pour the vinegar into the bleach slot.
If your washer has a self-clean setting, set it to that and run the washer.
If your washer does not have a self-clean feature, set the unit to the longest, hottest and deepest water setting. So say for mine I would set it to hot water, heavy soil and large load. Now run the washer.
Once the cycle has ended make sure to check the drum for powder that did not dissolve (should not be any). If there is run a rinse cycle. After that you are done.
