Although you maintain your sandals clean, the hygiene of the sandals remains questionable. This is because sweat and bacterial contamination can cause your sandals to stink very badly. To avoid the unpleasant odor you can wash your sandals in an empty dishwasher as it is the easiest and convenient method of cleaning. You can also place your sandals in the washing machine for cleaning in a medium runner. Avoid placing in the dryer and choose to dry in the sunlight. You can also use alcohol or bleach to remove the stink as they can remove the bacterial growth more easily.
