If you share your bathroom with a spouse or siblings, one of the most disgusting ways the sink gets dirty is from globs of toothpaste left behind by the people who brushed their teeth before you. Thankfully, the solution is simple.
The solution? A simple, $1 soap pump from the dollar store. Load it up with the toothpaste of your choice, put it next to the sink, and enjoy greater control of where the toothpaste is going, and your cleaner sink.
