Place vinegar in your washing machine. Here’s why. This is something appliance repairmen will never tell you.

How to Use Vinegar in Your Washing Machine
For Regular Maintenance:
Once a month, run an empty hot water cycle with two cups of white vinegar. This will help clean the drum, hoses, and other internal components of your washing machine.
For Odor Removal:
If you notice a musty smell in your washing machine, add two cups of white vinegar to an empty hot water cycle. For persistent odors, you can also leave a cloth soaked in vinegar inside the machine overnight before running a cycle.
For Cleaner Clothes:
Add half a cup of white vinegar to the fabric softener compartment during the rinse cycle. This will help remove detergent residues and leave your clothes softer and fresher.
For Brightening Whites and Colors:
To brighten whites, add a cup of vinegar to the wash cycle along with your regular detergent. For colors, add half a cup to the rinse cycle to help maintain vibrancy.
Why Appliance Repairmen Might Not Tell You This
Appliance repairmen might not openly share this vinegar trick for several reasons. Firstly, regular maintenance using vinegar can significantly reduce the likelihood of issues that require professional repair services, potentially impacting their business. Secondly, the simplicity and cost-effectiveness of this method might deter customers from purchasing more expensive commercial cleaning products and services that are often recommended by repair professionals.
