The material itself is antibacterial in nature because it does not have pores like regular sponges and cloths do, so basically there's no pores for the bacteria to inhabit on these silicone dish scrubbers
It's also much easier to keep it clean and dry than regular sponges since it does not absorb water and does not "sour" like cloth or sponges.
If you still want to wash it really well since food particles left in the little scrubbers might grow bacteria, you can also boil these or pop them in your dishwasher.
The silicone antibacterial sponges are designed to be dish scrubbers or veggie scrubbers,it can be also used as coasters or pot holders.They can even be used to clean makeup brushes or used to take a bath!
