Like I've mentioned before, I hate cleaning the shower. So, once I get the shower clean, I want it to stay clean for a long time. Unfortunately, with our hard water we'll start getting streaks of dripping water with the very next shower we take.
To combat the soap scum on the shower doors, I decided to spray Rain-x on the shower doors to make them water repellent and keep them clean longer.
I sprayed Rain-x 2-in-1 Glass Cleaner on my clean doors and wiped down with a microfiber cloth (although you can probably use any cloth). Be sure to use your exhaust fan and open any windows for ventilation and then wait a couple of hours before you wet the glass again.
The next time you shower, the water will repel on the glass, and you can use a squeegee to wipe down the glass after your shower. It's amazing how much cleaner the glass is staying!
