Over time, the combination of soap residue, hard water minerals, and body oils can build up, leaving a dull film on the glass door. While it may seem challenging to clean, we’ll show you how to tackle soap scum using simple ingredients and methods.

What You’ll Need

Before diving into the cleaning process, gather the following supplies:

  1. Vinegar or Lemon Juice: Both of these acidic liquids work wonders on soap scum. Choose one based on your preference.
  2. Baking Soda: A versatile cleaning agent that helps scrub away stubborn scum.
  3. Spray Bottle: To mix and apply your cleaning solution.
  4. Microfiber Cloth: Ideal for cleaning glass surfaces without streaks.
  5. Water: You’ll need this for rinsing.
  6. Rubber Gloves: Protect your hands during the cleaning process.

Step 2: Wet the Shower Doors

  • Start by spraying the entire surface of the shower doors with your cleaning solution. Make sure the glass is thoroughly wet.

Step 3: Apply Baking Soda

  • Sprinkle baking soda generously over the wet glass. The baking soda will create a paste when mixed with the vinegar or lemon juice, which is excellent for scrubbing away soap scum.

Step 4: Let It Sit

  • Allow the baking soda and cleaning solution to sit on the glass for about 15 minutes. This dwell time helps to soften and loosen the soap scum.

Step 5: Scrub Gently

  • Take a microfiber cloth or a non-abrasive sponge and start scrubbing the shower doors in a circular motion. Apply gentle pressure to remove the scum but be cautious not to scratch the glass.

Step 6: Rinse Thoroughly

  • Use warm water to rinse off the cleaning mixture from the shower doors. Ensure that all residue is completely removed.

Step 7: Dry and Buff

  • Grab a clean microfiber cloth and buff the glass dry. This will leave your shower doors sparkling and streak-free.
