To eliminate the musty odor, you can create a simple yet powerful cleaning solution by mixing alcohol and water in a ratio of 1:1:2. For example, you would use one part alcohol, one part water, and two parts of a suitable neutral solution, such as fabric softener or vinegar. Once you have prepared the mixture, pour it into a spray bottle for easy application.
Spray the solution lightly onto the affected areas of the clothing, ensuring that you cover the fabric without soaking it. The alcohol works to neutralize odors, while the water helps to dilute the solution and distribute it evenly across the fabric. Allow the clothing to air dry in a well-ventilated area, which will further help eliminate any lingering smells.
