Ah, toilet bowls.
That thing that everyone uses but no one wants to touch.
Make things a little easier on your cleaners (and more pleasant for your guests) by putting a toilet bowl clip on the insides of your toilets.
You can buy ones that are just air fresheners, or ones that are actually supposed to clean the bowl as well. (Although frankly, I’m skeptical of a product that says it can clean something with no elbow grease at all.)
