When the machine is full, stop the cycle and add your clothes. Let it sit in the solution for about five minutes. Add your normal detergent and restart the washing cycle (see Resources below).
- Always do a small spot-test before using any solution on colored clothing. Carefully read and follow the instructions and be aware of the ingredients listed on every product or solution. Read your clothing care label to make sure you do not permanently damage delicate materials.
