Have you ever noticed dark or black spots on your tile surfaces that look dingy and unappealing, often accompanied by a lingering smell? This could be a sign of mold growth on your grout lines.
It’s essential to address mold as soon as you notice it, as it can pose serious health risks for you and your family. But how can you be sure it’s mold, and what’s the best way to remove it? In this guide, you’ll learn four effective methods to identify and remove mold from grout. Hop on to learn more.
Ways to Identify Mold Growth on Grout
⇒ Inspect for Color, Texture, and Odor
The first way to identify mold growth is to see visual cues. Look closely at the grout lines for any dark, black, or greenish spots indicating mold. Mold often has a fuzzy texture and emits a musty, damp smell. If you notice any of these signs, mold is likely present.
⇒ Use Fiber Optic Cameras
If you can’t see the visual cues but find odors, you can use fiber optic cameras. It can help you inspect hard-to-reach spots where mold might grow, like in deep grout lines or corners. They allow you to see hidden mold without tearing up tiles. It makes it easier to spot mold that’s not visible to the naked eye.
⇒ Home Mold Test Kits
A home mold test kit is another way to identify mold growth. Follow the kit instructions and compare results to determine if you have mold. They’re a helpful tool for confirming the presence of mold before starting any cleaning.
⇒ Bleach Test
If you don’t know how to use mold test kits, you can have a simple bleach test on your grout. Apply a small amount of bleach to a suspected moldy area. If the dark spots lighten or disappear, it’s likely mold. If the spots remain unchanged, it may just be dirt. Always use gloves and proper ventilation when handling bleach.
4 Ways to Remove Mold from Grout
1. Baking Soda Paste
Once you identify the mold, the first method you can try is baking soda paste. Make a paste by mixing baking soda with water until it’s thick. Apply it directly to the moldy grout lines and scrub with a brush.
Baking soda is mildly abrasive, which helps remove mold and grime without damaging the grout. Rinse with water to finish the cleaning.
2. Vinegar and Water
If you don’t see the expected results using the first method, try our vinegar solution. Mix equal parts white vinegar and water in a spray bottle. Spray it onto the moldy grout and let it sit for 10-15 minutes. Scrub with a brush, then rinse with clean water.
Vinegar’s acidity kills mold naturally, making it an eco-friendly option for removing mold stains.
3. Hydrogen Peroxide
One of the most effective mold-removing solutions is hydrogen peroxide. Apply 3% hydrogen peroxide directly to the moldy grout. Let it sit for about 10 minutes, then scrub it with a brush.
Hydrogen peroxide is an effective disinfectant that kills mold and lightens stains. After scrubbing, rinse the area with water to remove any remaining residue.
4. Bleach Solution
Finally, as you have tested with bleach, you can use bleach for complete elimination of mold from grout. Mix equal parts bleach and water in a spray bottle. Spray the solution onto the grout and let it sit for a few minutes.
Scrub with a brush, then rinse thoroughly. Bleach kills mold on contact, but always use gloves and ensure good ventilation when working with bleach.
