Method 6 for Cleaning your Toothbrush: Cover It
The bathroom is full of nasty germs. Because of that, some people choose to put a toothbrush protector over their toothbrush, or keep their toothbrush in the medicine cabinet. However, this method can cause problems if you cover the toothbrush before it has a chance to dry thoroughly. Using a toothbrush cover with holes helps the toothbrush to air out if by chance it was not completely dry before covering.
An easier method to help avoid airborne contaminants landing on your toothbrush may be to be conscious of things such as keeping your toothbrush on the sink counter that is as far away from the toilet as possible, and being sure to close the toilet lid before flushing the toilet.
