Hard water deposits in the form of white spots are often found on glass surfaces. It is caused by the high levels of calcium and magnesium in the water. Unfortunately, these stains are not easy to remove. However, with the help of various means it is still possible to restore the glass to its original shine. There are also ways to ensure that the glass stays clean for as long as possible.
Method 1 of 3: Using liquid detergents
Step 1. For best results, use acidic products
Since hard water stains are alkaline, the best way to remove them is powerful acid. Look for a cleaner that contains phosphoric acid, sulfuric acid, or hydrochloric acid, as these acids should effectively deal with these stains. Read the directions on the label and follow the directions on the label to apply the product to the coated surface.
- Acidic products are toxic, so be sure to take precautions when handling them. Wear safety goggles and gloves and do not use these products to clean food contact surfaces such as kitchen countertops.
- Acidic cleaners are suitable for enamel and acrylic surfaces, but can damage many other materials, including natural marble, stone, terrazzo, anodized or polished aluminum, and colored grout. To avoid spoiling anything, try on an inconspicuous area before applying the product to the entire surface.
Step 2. Mix salt and water
Make a mixture of salt and water and use it to remove plaque. The salt acts as a sanding powder and will help scrape off the stain. Apply the mixture to the surface to be cleaned, take a clean cloth and rub in a circular motion. When finished, rinse the glass thoroughly to remove any remaining salt.
Step 3. Use white vinegar
Acetic acid helps remove hard water stains without leaving streaks on the glass. In addition, it is a fairly safe product that will not harm your health.
- Add lemon juice to vinegar to boost its potency and add a fresh citrus scent. Lemon juice (another acidic agent) acts on limescale in the same way as vinegar.
- Pour vinegar and lemon juice into a spray bottle and heat it slightly in the microwave (20-40 seconds depending on the type of oven). A heated product will help you clean stains more effectively than a cold product or room temperature. Just be sure to remove the cap from the bottle so it doesn't explode in the microwave.
- Apply the product to the glass and let it sit for 2-3 minutes. Dry with a dry, lint-free cloth or paper towel.
- To remove stubborn water stains on glasses and other small glass items, fill a bowl with a 50/50 solution of vinegar and water and leave the glass items in the solution for several hours. Then rinse them thoroughly.
Step 4. If we are talking about glassware, add a special rinse aid to the dishwasher
It will help remove hard water deposits from dishes. Pour the rinse aid into the appropriate compartment of the machine, add your usual dishwashing detergent and rinse the dishes to make them clean and clear.
Step 5. Add ammonia to the cleaning agent
To remove hard water stains, you can add ammonia to your glass cleaner.
Step 6. Ask the seller for advice on the remedy you need
If the aforementioned remedies still do not work, you can purchase stronger remedies from your local hardware store or household chemicals department. However, be careful and follow all directions on the packaging, as these usually contain harsh chemicals.
Method 2 of 3: Using non-liquid detergents
Step 1. First, work with your hands
Try to scrub the stains before using expensive or potentially harmful cleaning products.
- Use a magic eraser or other sponge that won't scratch. Use these products to safely clean your glass surfaces. Try removing stains with a glass sponge.
- You can use baking soda as an abrasive, but never use hard brushes or other abrasive materials to clean the glass. Otherwise, the glass will be scratched.
- This method is most effective for small stains and fresh plaque that has formed very recently.
Step 2. Use toothpaste
Toothpaste is a great alternative to baking soda.
- Apply regular paste to a damp towel and rub it over the stain in circular motions.
- Wait a few minutes and then wash off the paste with a solution of equal parts water and vinegar.
Step 3. Use special cleaning agents
There are several commercial cleaning products available for this kind of stains. They usually have the consistency of a paste.
- The main advantage of using the paste is that it does not leave behind light streaks or streaks from water.
- However, the flip side of the coin of using pasty products is that they can leave behind cloudy marks if not properly wiped off. Be sure to follow all directions on the label to avoid this unpleasant effect.
Method 3 of 3: Preventing Hard Water Plaque
Step 1. Prevent plaque build-up before it appears
One of the best ways to get rid of stubborn water stains is to eliminate the cause of the stain, which is the level of water hardness.
- You can use a water filter built into the water supply system.
- You can also use water softeners.
Step 2. Wipe and clean glass surfaces regularly
Remove water from glass surfaces. Do not let it dry on glass.
- Wipe the shower doors after each use with a lint-free towel or rubber scraper to remove water spills.
- Wipe down the glass every week to prevent stains.
- Act quickly: the longer the stain is on the surface, the more difficult it will be to remove. It can permanently bite into the surface of the glass.
Step 3. Prevent the appearance of future stains
You can also prevent stains by using special glass protection.
- Remember to use glass coasters for glass tables. This prevents drops and splashes from reaching the table. In addition, the use of coasters will help prevent round stains on the table.
- For shower doors, apply a wax-based protective coating about once or twice a year. The water will flow over the wax coating and your door will remain clear and clean.
- If you are unsure if a product is safe for a given type of surface, test it in an inconspicuous area.
- If the stain cannot be removed immediately, reapply the product, leave it on for a few minutes, and wipe the area again. Repeat the process as needed.
- Use a sponge, not a rag; sponges are more efficient and less abrasive.
- Follow label instructions and wear appropriate protective clothing (gloves, goggles, face mask) before using chemicals.
- Never mix ammonia and bleach.
