My mother in law boils the silver utensil for 10-15 minutes.  Is it okay to boil?

wash it with warm water every time you are using it. silver itself is antibacterial so no need of sterlization. I also feed my son with silver bowl n spoon.

I used steel bowl. <font color ="#3b5998"><b> @6372999217d2c800158d8bec </b></font>?
