For the most part, I think we are all pretty good at swishing the toilet brush around in the toilet bowl. What we often miss; however, is cleaning the underside of the rim and the siphon jets {these are the holes underneath the rim where the water actually comes out}. If you are starting to notice vertical stains along the sides of your toilet bowl, this is a sign that they need to be cleaned. Often times, toilet brushes can’t quite get up into these spaces, and over time, grime builds up.
