cleaning glass with hard water or calcium stains

I've been trying to clean my shower glass with CLR and a razor/scraper... it gets 85% of the calcium deposits, but I really want to get it all... anyone have a suggestion for a next step?

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. Youll also save money and the hassle of needing to stock more cleaning supplies.

Its 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 dont 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.

You can save yourself a lot of work by starting over by purchasing a new shower door. Coat the door with a hard surface coating like Rain X. Then get in the habit of using a shower squeegee to remove the water from the door after every shower use. This will keep the mineral deposit from adhering to the glass. You will only need to put additional coats of Rain X about once a month.

Also keep in mind that shower doors are tempered glass. Using a razor/scraper on tempered glass can easily leave nasty scratches.
