Try white vinegar first to loosen the worst stains. If you can drape a vinegar soaked towel or sheet over the door and let it sit for a while.

Then use gel gloss glass cleaner It cleans waterspots from glass and gives it a protective coating so spots stay away

I am amazed how well vinegar gets off those mineral deposits around my faucets. Try it.

I've been through this with our home that is now 15 years old. For many years before we remodeled our bathroom I was stymied by what seemed to be hard water stains on our glass (it's different, by the way, on tile). Glass is etched by our repeated use of cleaners and eventually, the water is etched into the glass and will never, never be cleaned out. If you are not in a position to remove and replace the glass, stop, STOP using caustic cleaners on your glass. Vinegar will remove immediate deposits but will not remove the etched-in deposits of repeated toxic cleaner use. You can try other non toxic glass cleaners that might brighten your glass as a whole, but you will not remove the etched in deposits from the past. Sorry -- been there.

Instead of harsh chemical sprays, get those windows and mirrors crystal clear with a simple solution of white vinegar, newspaper and a little elbow grease. YouÂll also save money and the hassle of needing to stock more cleaning supplies.

ItÂs simple: get some white distilled vinegar and dispense into a used spray bottle. Squirt on, then scrub with newspaper, not paper towels, which cause streaking.

If you donÂt like the smell, you can add 4 tablespoons of vanilla extract or lemon juice depending on your preferred scent.

If there are any stubborn stains you can sprinkle baking soda on them after you spray with vinegar and scrub with a sponge.

I think you should try vinegar. It will remove that spots completely. It smells a little different, but if you are not a smell sensitive person, you won't have any problem.
