Exchange your laundry detergent for baking soda
Use only 50cc or a light 1/4 cup. Don't be tempted to use more. Less is better. For really dirty Laundry run a longer wash cycle to give the detergent time to work. But don't add more soap, it's the washing action that cleans the laundry not the detergent. Always use HE laundry detergent. Non HE will leave a soap scum in your HE machine.
