Method 1: Water + Vinegar + Salt
If the water stains on your shower glass are yellow or even black, they are considered stubborn stains that are difficult to remove. You can use a solution of 50% vinegar mixed with 50% water, with a small amount of salt added. Spray this solution onto the shower glass door. After waiting 10-15 minutes, wipe with a dry cloth, and the stains will be removed. Alternatively, you can immerse a towel in the solution and wring it out to be damp. After 5 minutes, wipe the glass door with the damp towel, and you will see immediate results.

Method 2: Alcohol + Newspaper
If the water stains on the shower glass door are white or pale yellow and the stains are moderately severe, you can use old newspapers to clean them. The ink on the newspapers has good absorption properties. Before using the old newspapers, pour 75% alcohol into a spray bottle (95% alcohol should be diluted first) and spray it onto the stained areas of the glass. Then, fold the old newspaper and wipe the glass. The glass will look like new immediately.
Method 3: Tea + Plastic Wrap
If the stains on your shower glass are in the form of white blocks or particles, and the severity is moderate, especially in bathrooms near the kitchen, you can try the following:1. Place a plastic film over the stained area on the glass door.2. Wait 10 minutes to allow the hardened white particles to soften.3. Remove the plastic film.4. Use a clean towel to wipe the glass with strong black tea (overnight tea is best). The stains should disappear.
Method Four: Toothpaste/Lemon Water
If white or light-colored watermarks appear on the shower enclosure glass, the stains are relatively light. In this case, simply apply a small amount of toothpaste to the watermark, wipe with a damp cloth, and rinse with clean water. Alternatively, soak lemon slices in water and pour the lemon water into a spray bottle. Then, spray the lemon water onto the glass door in a large "X" shape, and repeatedly wipe along the "X" shape. once the glass is 70% dry, rinse with warm water, and the shower enclosure glass will be clean and restored.
Method Five: Soap + Cloth
For situations with mild water stains on glass, you can wrap the remaining soap residue in a cloth or old stocking and then wipe the stained area of the glass. Finally, clean with warm water and dry with a clean cloth. Showers will be as good as new, and the glass will not easily accumulate moisture.
Method Six: Scraper
For persistent fog and water vapor buildup on shower enclosure glass doors, a glass scraper can be used. By removing the residue before it turns into water spots, you can easily and affordably clean the glass after showering.
