Silicone toilet brushes are generally more hygienic than traditional brushes, as the bristles of a silicone brush are nonporous and don’t absorb bacteria.
This makes them easier to clean as dirt and germs won’t get stuck in the brush’s bristles, so they won’t be transferred back to the toilet.
As silicone brushes don’t require scrubbing and won’t scratch surfaces when cleaning, they are also kinder to the surface of your toilet.
