How to Make Yellow Glass Clear Again

Glass windows and objects can lose their clear, pristine appearance over time, especially if exposed to sunlight, pollutants, or improper cleaning methods. Yellowing of glass can be unsightly and can diminish the overall aesthetic appeal of your home or belongings. Fortunately, there are several methods you can try to restore yellowed glass to its original clarity. In this article, we will explore some effective techniques to make yellow glass clear again.

1. Use vinegar and water solution: Mix equal parts white vinegar and water in a spray bottle. Spray the solution onto the yellowed glass and let it sit for a few minutes. Wipe the glass clean with a microfiber cloth or sponge. The acidity of vinegar helps break down the yellowing residue.

2. Baking soda paste: Create a paste by mixing baking soda with water. Apply the paste to the affected glass and gently scrub it using a soft cloth or sponge. Rinse thoroughly with clean water. Baking soda’s mild abrasive properties can help remove stubborn yellow stains.

3. Lemon juice and salt: Squeeze fresh lemon juice onto the yellowed glass and sprinkle a small amount of salt over it. Using a soft cloth, gently rub the mixture onto the glass in circular motions. Rinse well with water. The citric acid in lemon juice acts as a natural bleaching agent.

4. Hydrogen peroxide: Apply a small amount of hydrogen peroxide onto the yellowed glass and let it sit for a few minutes. Wipe it off with a clean, damp cloth. Hydrogen peroxide can effectively break down yellowing agents and restore clarity to the glass.
