For really tough hard water stains, try scrubbing with some hydrogen peroxide. Yep, the same stuff you have in your first aid kit. Hydrogen peroxide plus some elbow grease should banish even the most stubborn of hard water spots from your metal fixtures.
So, hydrogen peroxide, baking soda, vinegar, and toothpaste are all effective at removing hard water stains from your house.
A paste of baking soda and hydrogen peroxide cuts through soap scum and hard water stains on tubs and tiles.
It is also widely used in horticulture. It is a versatile product. In addition to disinfection, the use of hydrogen peroxide helps to remove limescale and corrosion.
Don't mix hydrogen peroxide and vinegar together in the same mixture. This can create peracetic acid, which may be toxic and can irritate your throat and lungs, eyes and skin.
Mix equal parts lemon juice and distilled white vinegar in a spray bottle. Spray the vinegar and lemon juice stain remover on the stain. Let the cleaning solution work on the stain for about five minutes. Use a microfiber cloth to rub the stained area until the stain is gone.
Professional window cleaners like Window Genie are trained and experienced in this battle. Window Genie uses a polishing paste specifically designed to fight the minerals that create these stains. The paste is applied to a non-abrasive cleaning pad and the window is lightly scrubbed.
Vinegar works well on dirt, mold and mineral deposits as well as on other acid stains including coffee. Therefore, you may have found vinegar did a good job removing your coffee or tea stain. Hydrogen peroxide works differently than vinegar and is better at removing different types of stains.
Miracle Stain Remover
It was essentially 2 parts hydrogen peroxide, and 1 part Dawn dish soap. Now, it can be any dish soap quite frankly, although Dawn does work really well, but so do other dish soaps. The most important thing here is that you treat the stain the way you would treat any stain.
However much you are making, just add twice as much hydrogen peroxide as you do the detergent. So for a small stain mix 1 teaspoon of Dawn with two teaspoons of peroxide. For a large batch 1 cup of hydrogen peroxide to ½ cup detergent works!
Contrary to other chemical substances, hydrogen peroxide does not produce residues or gasses.
Removing Hard Water Deposits From Faucets
Use vinegar to help loosen the hard water film and buildup before scrubbing. Soak a clean rag in vinegar and drape it over the faucet, making sure there is direct contact with all of the hard water deposits. Let the rag sit for at least 30 minutes; an hour is better.
Use Dawn and some hot water and a cloth or sponge to get into those nooks and crannies where grime and scale tend to build up. You can also combine Dawn with vinegar for stronger cleaning power, especially when tackling hard water stains.
Grab a spray bottle and mix equal parts water and vinegar (you can also add a teaspoon of Dawn dish soap for more clinging power). Spray the solution on the bathtub stains, let it sit for at least 15 minutes, then wipe clean. Let the solution sit longer depending on the severity of the stains.

Hydrogen peroxide also kills normal cells within the wound — including healthy skin cells and immune cells — and slows blood vessel formation, all of which are important for wound healing. It's a similar story with rubbing alcohol, another substance commonly thought to help sanitize a wound.
Mixing hydrogen peroxide and baking soda causes a chemical reaction that produces carbon dioxide and certain other chemicals which can cut through soap scum and hard water stains.
OxiClean contains several ingredients, but the important one for boosting and brightening laundry is sodium percarbonate — basically, dry hydrogen peroxide plus washing soda (also called sodium carbonate, which is very similar to but not exactly baking soda).
