How to Clean Shower Doors With a Simple Vinegar Spray

After several showers, even the clearest of glass doors are bound to get spotted and streaked with residue. And if not dealt with promptly, soap scum can become a breeding ground for bacteria and even promote mold growth. Fortunately, all you need to be rid of it sits within your kitchen cabinet. A simple vinegar spray does what the store-bought cleaners can do—but for far less money and without all the chemicals.

Ahead, the best way to safely and effectively use household vinegar to return your shower doors to pristine condition.

Safety Tips

Vinegar is acidic, explains cleaning specialist Iryna Balaban, which makes it a "very efficient cleaner since it can easily dissolve any mineral deposit, soap scum, and hard water stains that may form on glass surfaces over time."

Plus, it's "a safer alternative to many commercial cleaners," adds Alicia Sokolowski, president of AspenClean. "It is natural, non-toxic, and doesn’t release harsh fumes."

Still, since vinegar is acidic, it pays to proceed with caution. Keep these safety tips in mind when cleaning with vinegar.

• Do not use vinegar on natural stone surfaces, such as marble, as the acid can etch the surface.
• Test the product in a small area first, especially if the door has coated glass or decorative finishes.
• Never mix vinegar with any other chemicals, especially bleach or peroxide. This can create toxic gases.
• Avoid using steel wool and other abrasive tools on glass shower doors to prevent scratching.
• Always ventilate the bathroom when cleaning with vinegar to avoid irritation to the nose, throat, or eyes.

Step-by-Step Instructions for Cleaning Shower Doors With Vinegar

Follow Sokolowski’s expert steps below to make your cloudy shower doors spotless via the power of vinegar.

1. Make sure that your shower doors are dry before you begin.
2. To prepare the vinegar spray, combine 1 part white vinegar with 1 part water in a spray bottle. For extra cleaning power, you can heat the vinegar slightly—but do not boil it.
3. Spray the vinegar solution generously onto the glass doors, ensuring that you cover areas with visible soap scum or hard water stains.
4. Allow the solution to sit for about 10 to 15 minutes, allowing the acid time to break down any hard mineral deposits. For tougher spots, increase the time up to 30 minutes.
5. Use a soft sponge or microfiber cloth to wipe down the doors. For any stubborn spots, sprinkle a little baking soda onto the sponge and gently scrub. The mild abrasiveness will help lift residue without scratching the glass.
6. Use warm water to rinse away the vinegar and loosened grime.
7. Wipe the doors down with a dry microfiber cloth. A squeegee is helpful to prevent water spots. 

Tips and Tricks for Preventing Soap Scum Buildup

There are several preventive measures you can take to keep soap scum and mineral buildup from forming on your shower doors. These top three tips will help you avoid future heavy maintenance.

• Keep the bathroom ventilated so that moisture doesn’t linger, advises cleaning expert Ryan Knoll.
• Use a squeegee after every shower in order to prevent soap scum and minerals from building up. Lightly spray doors with a vinegar solution once a week to keep them sparkling. Spot-clean as needed when you notice fresh water marks, says Knoll. 
• Address buildups early, says Knoll. “Fresh spots come off easily. Old scale buildup becomes a much bigger project.”
