Toothbrush cleaner comes in many forms, from the ultraviolet light in sanitizer units to the ingredients in certain cleansing tablets. Tablets dropped in water bubble up to remove germs (supposedly up to 99%) and excess toothpaste in about 10 minutes. A second type of cleaner figures as a plastic snap-on product; this fastens to the head of a toothbrush and emits natural disinfecting vapors in flavors like cinnamon. An environmentally safe, non-toxic method of toothbrush cleaning is organic grapefruit seed extract. Drops of this potent product are placed into water to disinfect and sanitize toothbrushes.
