It's not you. It's the water your brush never lets go of.
You flush, you put the brush back, and you try not to look. Hundreds of packed nylon bristles hold on to the toilet water, then the brush sits in a closed holder until you notice the disgusting puddle in the base and the stains that won't rinse out. Almost nobody cleans their toilet brush, and nobody wants to. A brush that stays wet is a brush that turns gross. That's the trap, not the way you clean.
Two shakes and it goes back almost dry
Think of a wet towel balled up in a hamper, then the same towel hung on a hook. Silicone is the towel on the hook. Water doesn't cling to its silicone bristles, so you shake it twice over the bowl, rinse it in the flush, and it goes back almost dry. Whatever still drips lands in the base, not on your floor. Nothing sits, nothing soaks in, and it still looks like a brush the next time you pick it up.
A toilet brush you don't have to hide
The flat, flexible head slides under the rim and the silicone tip gets into the corners, so the spots a guest might notice get cleaned too. Keep it on the floor or stick the base on the wall, no drilling. In green, orange or white, it's the one brush you can leave in plain sight. No refills to restock, and one for every bathroom, upstairs and down.
