Removing mildew smells
Mildew smells can be easily eliminated with the help of some baking soda. This substance is one of the most popular household products for removing bad odors.
The first thing you need to do is remove the mildew.
Applying the baking soda
After you have removed the mildew, sprinkle some baking soda on the affected area. Let it sit for 3 hours before cleaning it.
The baking soda will absorb the odors and it should be left even longer, and applied even more, for powerful unpleasant odors.
