I’m of the theory that showers are too difficult to clean from the outside, and I much prefer to clean mine while using it.
I keep a scrub brush and spray bottle of hydrogen peroxide in the shower for a quick all-over scrub of the walls, floor and crevices around the door. Periodically the floor needs a scouring, which requires baking soda and a little more elbow grease. A daily spray of hydrogen peroxide in areas prone to mold help keep it in check, as does an all-over squee-gee to remove water drops before you exit the shower.
Tubs that are used often will also need periodic scourings with baking soda and water. On a weekly basis, spray with vinegar water and wipe down with a damp rag, then rinse.
I admit. I was a skeptic when I read that vinegar and soda could really clean my bathroom. But after the learning curve, I’m convinced my bathroom is cleaner now than it was with those toxic chemicals.
What you will need:
1-2 clean dry rags, old washcloths work well
1 spray bottle (don’t reuse a spray bottle that has had chemicals in it; some can react to non-toxic ingredients like vinegar to make deadly gases)
1-2 paper towels
vacuum or broom
3% hydrogen peroxide (optional)
essential oils fragrance spray (optional)
In the spray bottle, prepare a solution of 1 part vinegar to 3 parts water. Vinegar is an excellent cleanser of grime, and a mild disinfectant as well. If the odor annoys you (or brings back childhood memories of Easter-Egg dying), rest assured the smell will dissipate when the vinegar dries.
