Grout in my shower has been always very challenging. Mold and mildew grows in the grout all the time and stain the grout in pink or brown. It’s likely caused by excess moisture and humidity, which creates the perfect environment for mold to thrive. In addition, grout is porous and it easily soaks up dirt, oils, and stains, especially in damp areas like the bathroom and kitchen. Cleaning those tile grout is often overwhelming. Here are some tips for the grout cleaning, which will help you complete the job easier and effectively. Regular grout cleaning can help prevent buildup and make your tile surfaces last longer.
What is Tile Grout?

Grout is the material between your tiles that keeps them in place and gives a finished look. Made mostly from cement, grout tends to trap mold, stains, and discoloration because of its porous nature.
Common Grout Cleaning Challenges
Grout is tricky to clean because it’s so porous, leading to issues like:
- Mold and Mildew: Common in bathrooms due to high moisture levels.
- Stubborn Stains: Dirt and oil can seep into grout over time, leaving stains.
- Grease and Food Particles: Kitchen grout often picks up grease and food splatters, causing discoloration.
Best DIY Grout Cleaning Solutions

Harsh chemicals, such as bleach, can be very effective on the grout cleaning. However, grout cleaning, especially in the shower, needs to be done in a closed area. Children are at greater risk from breathing bleach vapors because their lungs are still developing. Bleach can irritate the skin and eyes. Breathing in bleach over a long period of time can increase your risk of cancer. In addition those harsh chemicals may damage grout. Therefore, many people prefer homemade grout cleaners—they’re safe, eco-friendly, budget-friendly, and easy to make. Here are some tried-and-true methods:
