Outside of washing them regularly, there are ways that you can cut down on the awful smell that your pads may be emitting. The easiest way is probably going to be to just wash them on a regular basis but you can also perform this method (even though this is basically another form of washing them). With a bucket of warm water, a tablespoon of mild soap, and a full cup of baking soda place them inside and allow them to soak for a good 30 minutes. After this time has passed, go ahead and rinse them off thoroughly with lukewarm water.
