Just like many other cleaning tools, your mop can develop an unpleasant sour smell over time. The mop itself may still be in good condition, but you might feel like replacing the mop. Before investing, however, deodorize your mop and implement an extra step into your cleaning routine to prevent the odor from recurring. Your best allies for fighting odor are common household supplies like white vinegar and baking soda.
Rinse the mop in hot water after cleaning up milk or other liquids to remove excess residue that can lead to odor. Thoroughly wring out the mop after each use and allow to air dry.
Fill your cleaning bucket with equal parts of water and white vinegar. Add 2 cups of baking soda per gallon of liquid used.
Plunge the mop into the bucket and let it soak for about 30 minutes. The vinegar and baking soda are two natural deodorizers, while the vinegar will disinfect the mop.
Wring out the mop completely and allow it to air dry. Repeat as needed to keep the mop clean and free of odors and bacteria.
