To save money by saving your large appliances, you must take care of them. Your washing machine is one of your large appliances. To clean your washing machine, run a gallon (for a large machine) of vinegar through a hot- full size wash cycle and wipe it out with a clean cloth. Generally, I do this twice a year. Although, I wipe down the washing machine and the dryer about once a week. This will also save you money on clothes maintenance.
