Solution -> Ensure that the washing machine is not overloaded with clothes. This allows for proper agitation and rinsing, which is essential for removing dirt and detergent residue that can cause dullness.
Explanation -> When the machine is overloaded, clothes don't have enough space to move freely, and the detergent may not distribute evenly.
any notes required -> Follow the manufacturer's guidelines for the maximum load capacity of your washing machine.

Avoid overloading the washing machine.
