How to Clean Grout

Grout, the material used to fill gaps between tiles, is notoriously difficult to clean. Over time, it can accumulate dirt, stains, and mold, making it look unsightly and compromising its integrity. The longer you let it sit, the harder it becomes to remove, turning what could have been a quick job into a time-consuming chore. This is particularly true in bathrooms, where moisture is constantly present, leading to frequent grout staining and mold buildup, especially in the shower.

Let’s go through why grout gets dirty, how to clean it effectively, and how to maintain it so you don’t have to spend hours scrubbing away stubborn grime.

Why Does Grout Get So Dirty?

Grout is porous, meaning it easily absorbs water, dirt, and other debris. In bathrooms, for example, moisture settles into the grout every time you take a shower. When it doesn’t dry completely—which is often the case in areas with poor ventilation—it creates a perfect breeding ground for mold, mildew, and bacteria. Over time, the grout may also stain from soap scum, hard water deposits, and even dirt tracked in on feet.

The best way to combat grout dirt is regular maintenance. However, if it’s already gotten out of hand, don’t worry—there are still ways to restore it to its former glory.

The Key to Clean Grout is Regular Maintenance

The best defense against dirty grout is regular cleaning. Cleaning grout often, even for just 10 to 15 minutes a week, will save you the hassle of deep cleaning down the road. The more frequently you clean, the less chance dirt, mold, and mildew have to settle into the grout.

To incorporate grout cleaning into your regular routine:

  • Set a schedule: Pair your grout cleaning with other household chores like wiping down countertops or vacuuming. This makes it easier to remember.
  • Choose gentle cleaning solutions: Avoid using harsh chemicals regularly, as they can degrade the grout over time. A mild detergent or a homemade vinegar solution will do the trick for regular maintenance.

Preparing to Clean Grout

Before you begin cleaning, it’s important to gather the right materials to ensure a safe and effective process. Here’s a list of items you’ll need:

  • Grout brush or toothbrush: A stiff-bristled brush is essential for getting into the small crevices.
  • Rubber gloves: Protect your hands from harsh chemicals.
  • Cleaner: We’ll go over the best cleaner options below.
  • Rags or sponges: These are used to wipe away excess dirt and clean.
  • Grout sealer: To protect the grout after cleaning.
  • Safety goggles: If you’re using any harsh cleaners or scrubbing vigorously, goggles will protect your eyes.
  • Fans and ventilation: If you’re cleaning in an enclosed area like a bathroom, it’s important to have proper ventilation. Open windows and use fans to circulate air and dry out the space.

Now that you’re ready let’s get into the cleaning process.

Step-by-Step Guide to Cleaning Grout

1. Choose the Right Cleaner

There are several cleaning solutions you can use to clean grout, depending on the severity of the stain and your preference for homemade or store-bought cleaners:

  • Vinegar and water solution: Mix equal parts vinegar and water in a spray bottle. Vinegar is a natural disinfectant and will help break down dirt and stains. For added cleaning power, mix in a little baking soda to create a paste.
  • Mild household detergent: A simple detergent mixed with water can be effective for regular cleaning without damaging the grout.
  • Bleach-based cleaners: If the grout is severely stained or has mold, you may need to use a bleach-based cleaner. Be cautious not to mix bleach with any acidic cleaners like vinegar, as this creates dangerous fumes.

2. Remove Surface Dirt

Before applying any cleaner, it’s important to remove any loose dirt and debris from the surface. Use a damp rag or sponge to wipe the tile and grout lines. This ensures the cleaning solution can focus on the stains and not on surface dirt.

3. Apply the Cleaner and Let It Sit

Once the surface is clean, spray or apply your chosen cleaner directly onto the grout lines. Let the solution sit for about 5 to 10 minutes to allow it to break down any deep-set dirt, mold, or mildew.

If you’re using a vinegar and baking soda mixture, you’ll notice it starts to fizz—this is a sign it’s working!

4. Scrub the Grout

Using your grout brush or an old toothbrush, scrub the grout lines vigorously. Work in small sections and make sure to apply even pressure to get into all the small crevices. If the stain is particularly stubborn, you may need to repeat this step several times.

Be sure to rinse the brush frequently to avoid spreading the dirt around.

5. Rinse and Dry

After scrubbing, use a clean rag or sponge to wipe away the cleaner and loosened dirt. Rinse the area with water to remove any residual cleaner, and then dry the grout completely. If you’re working in the bathroom, leave the windows open or use fans to speed up the drying process.

6. Seal the Grout

Once the grout is clean and dry, sealing it is a great way to protect it from future stains and moisture buildup. Grout sealer creates a protective barrier that fills in the tiny pores, preventing dirt, mold, and mildew from getting in.

To apply the sealer:

  • Run a thin line of grout sealer along the grout lines.
  • Use a clean rag to wipe away any excess that may spill onto the tiles.
  • Let it dry completely before using the area again.

Sealing grout is an excellent preventative measure, but keep in mind that you’ll still need to clean it periodically to maintain its appearance.

Professional Grout Cleaning Services

If the grout is too far gone for a DIY solution or if you simply don’t have the time, hiring a professional like First Class Green Cleaning may be the best option. Professionals use advanced techniques and equipment, such as steam cleaning and power scrubbing, to tackle even the toughest grout stains. Additionally, they can apply high-quality sealers that last longer than store-bought solutions.

When considering professional services, weigh the time and cost:

  • Time: Cleaning grout can be time-consuming, especially for larger areas or deeply embedded stains.
  • Cost: Professional services can be more expensive, but they provide a deeper clean and often offer guarantees for their work.

Tips for Maintaining Clean Grout

Now that your grout is clean, here are a few tips to keep it looking great:

  • Wipe up spills immediately: In kitchens and bathrooms, wipe up spills as soon as they happen to prevent stains from setting in.
  • Dry the grout after each shower: Use a squeegee or towel to dry the grout lines after every shower. This prevents moisture from settling and reduces the chance of mold and mildew forming.
  • Use a gentle cleaner for regular maintenance: A mild detergent or vinegar solution is sufficient for weekly cleaning.
  • Reapply sealer every 6-12 months: Depending on the level of use, grout sealers wear down over time and should be reapplied periodically.
