I bet you do not clean your washing machine regularly. Some of you might have not even thought of cleaning it, even once. But then again, why would you clean a washing machine when its function is to wash and of course, clean.
But actually a washing machine should be cleaned regularly of soap scums that get accumulated, so that it will function better.
It is very easy to clean and disinfect a washing machine. Just pour in 2 cups of distilled white vinegar into the soap compartment and then run the machine on a full cycle without adding any other detergent or clothes to wash.
It is as easy as that.
