The Ultimate Guide to Removing Mould from Your Shower Grout

Why Mould Grows in Shower Grout

Before we dive into the cleaning process, it’s important to understand why mould grows in shower grout in the first place. Shower grout is a porous material that absorbs moisture, making it an ideal breeding ground for mould. Mould thrives in warm, damp environments, and the bathroom provides the perfect conditions for it to grow.

Assessing the Severity of Mould Growth

Before you start cleaning, you’ll need to assess the severity of the mould growth. If the mould is limited to a small area, you may be able to clean it yourself using household cleaning products. However, if the mould covers a larger area or has been growing for an extended period, it’s best to call in a professional.

Tools and Materials You’ll Need

To effectively remove mould from your shower grout, you’ll need the following tools and materials:

  • Rubber gloves
  • Safety goggles
  • Respirator mask
  • Scrub brush
  • Spray bottle
  • White vinegar
  • Baking soda
  • Hydrogen peroxide

Step-by-Step Process for Removing Mould from Shower Grout

Now that you have all the necessary tools and materials let’s get started on removing the mould from your shower grout.

Step 1: Protect Yourself

Before you start cleaning, it’s essential to protect yourself from the harmful effects of mould. Put on rubber gloves, safety goggles and a respirator mask to avoid inhaling mould spores.

Step 2: Mix the Cleaning Solution

Mix equal parts white vinegar and water in a spray bottle. Spray the solution onto the affected area and let it sit for 10-15 minutes.

Step 3: Scrub the Grout

Using a scrub brush, scrub the grout vigorously to remove the mould stains. Rinse the area with water and repeat the process if necessary.

Step 4: Use Baking Soda

If the mould stains are stubborn, you can make a paste of baking soda and water and apply it to the grout. Let it sit for 10-15 minutes before scrubbing it off with a brush and rinsing with water.

Step 5: Use Hydrogen Peroxide

If the mould stains persist, you can use hydrogen peroxide to remove them. Spray the affected area with hydrogen peroxide and let it sit for 10-15 minutes before scrubbing it off with a brush and rinsing with water.

Step 6: Dry the Area

Once you’ve removed the mould stains, dry the area thoroughly to prevent future mould growth.
