Because we have two cats in the house, my obsession for hygiene is growing fast. After a while, you avoid leaving things without a cover and if it is a toothbrush, than it becomes more important. I was trying to find a solution for our toothbrushes but they are electronic, so the cases for toothbrushes don't fit them. However, I have discovered "Steripod". It contains herbal thyme which kills the germs on your brush. Steripod sanitizer clips onto the head of your toothbrush so it is really easy to use. Plus each Steripod lasts up to 3 months.
I have bought these two for 16 TL from a regular pharmacy but you can also find it online. If you are obsessed with hygiene too, you might want to give a chance to these sanitizers.
