I'm still on my personal challenge to clean the bathroom daily. But I've noticed a few things. First, the chemicals I use to clean this bathroom are kind of nasty. They're burning the skin off of my hands (yes, I should use gloves) and are pretty harsh on the lungs. So I've backed off on leaving the tub to soak in chemical juice for hours to bleach it clean. At least not every night. Just sometimes. I'm also watering the stuff down for use on the sink and toilet. Nothing fancy, just not spraying so much of it, and using a wet washcloth to apply it.
I've noticed that I like having a clean bathroom. It is easier to clean. Although it's surprising the amount of dust that arises in 24 hours.
But a more disturbing thing is going on. Ever since I started this effort in cleaning, Q has developed a migrating, disappearing, reappearing rash. I think it's simply coincidence, not causation, but since I cannot figure out what is going on, I'm leaving it as a possibility: Q may be allergic to clean.
