Hi Martha. I'm Cindy. At our old house we had hard water. I could clean our shower doors but they always looked cloudy. Until my husband was in Menard's one day and found a product called Scrubbing Bubbles. Must have a blue cap. You spray this on your shower doors and walk away. Wait a half-hour. Return and wipe the doors with a damp cloth. This product works and I recommend it.
Comet works great with a scrubby and Clorox cleanup or a cleaner with soap sum remover
Im considering the Rain X products for shower door care and maintenance. We have extremely hard water.
Hi Martha, you can use a calcium lime rust remover to get them clean as well, and to maintain them, you can hang a squeegee in the shower with a suction hook, and squeegee them after each shower, this will keep them looking great, then use scrubbing bubbles blue cap as a once a month clean if required
