Window Cleaning FAQs, answered by experts

Hard water stains can permanently damage your glass if left untreated. The minerals dissolved in the water can etch the glass, causing long-term damage and affecting the overall integrity of the surface. Luckily, it is pretty simple to remove hard water stains by using vinegar, baking soda, or commercial cleaners.

To maintain a glass shower door, clean it regularly with a non-abrasive cleaner to prevent soap scum and hard water stains. Using a squeegee after each use is also recommended. Additionally, periodically check for leaks and ensure all hardware remains secure to prevent long-term damage.

Do not mix bleach with vinegar, ammonia, acidic liquids, or other cleaners or detergents as toxic fumes result from the chemical reaction. Mix bleach only with water to avoid dangerous chemical reactions. Even mixed with water to dilute it, bleach can still be harmful to your skin, eyes, and lungs.

The simplest way to clean stained glass windows is by using warm distilled water and a damp cloth. Distilled water won’t corrode the stained glass or leave residue behind. Avoid using cleaners with alcohol or ammonia. However, you should only clean when necessary. Stained glass windows are fragile, and excessive cleaning could cause fading, weakening of the solder, or other damage.

Time varies by number and size of windows but usually 2-4 hours.
