Effective Methods for Cleaning Grout on Tile Floors

Quck answer

Cleaning grout on tile floors can be a tedious task, but it is essential to maintain the appearance and hygiene of your floors. Here are some steps to follow:

1. Start by sweeping or vacuuming the floor to remove loose dirt and debris.

2. Mix a solution of equal parts water and vinegar or water and baking soda. Both are effective natural cleaners.

3. Apply the solution to the grout lines and let it sit for a few minutes to loosen dirt and stains.

4. Use a small brush, like a toothbrush, to scrub the grout lines gently. Pay extra attention to heavily soiled areas.

5. Rinse the floor with clean water to remove any residue or cleaning solution.

6. Dry the floor thoroughly with a clean towel or allow it to air dry.

Regularly cleaning grout can prevent staining and keep your tile floors looking fresh and clean.


In order to truly clean your tile floor, it is essential to also pay attention to the grout. The narrow, porous lines that fill the spaces between the tiles tend to attract dust and germs. Discolored grout can make the entire floor appear old and dull. While there are various homemade solutions for cleaning tile grout, most of them are not strong enough to effectively tackle the challenges of grout cleaning. The most effective approach is often to use a commercial grout cleaner and, for stubborn dirt, a grout steamer.

Facts About Grout

Grout is used to fill in the gaps between tiles, providing protection for the edges and helping to keep the tiles securely in place. There are different types of grout available, with the three most common being unsanded, sanded, and epoxy. Typically, grout is composed of cement (usually Portland cement), an aggregate, and water.

Unsanded grout is commonly used when the space between tiles is less than 1/8 inch wide. It adheres better to vertical surfaces and is often preferred for marble tiles, as sand particles in other types of grout may scratch the tile surface during application. On the other hand, sanded grout contains silica sand and is typically used for tiles that are spaced more than 1/8 inch apart. It has a coarser texture compared to unsanded grout. Epoxy grout is primarily used by professionals in situations where the tile may come into contact with acids or oils that could compromise the adhesion of sanded or unsanded grout.

Alternative Grout Cleaning Solutions

Vinegar-based homemade grout cleaners are not recommended, as vinegar is acidic and can weaken the grout. Baking soda, although alkaline, is not potent enough on its own to effectively clean tile grout. Mixing baking soda with vinegar does not sufficiently alter its acidity to make it safe for grout cleaning. Hydrogen peroxide, typically diluted, is not strong enough to clean grout. While bleach is powerful, it is also toxic and emits strong fumes.

Manual Techniques for Cleaning Grout

There are several options for cleaning grout lines, such as commercial grout cleaners, grout bleach, alkaline floor cleaner, and oxygen bleach. For mildly soiled grout, mix the powder with warm water in a bucket and apply it to the grout lines using a sponge or cloth. Allow it to sit for 15 minutes, then scrub with a grout brush to remove any remaining stains. Mop the floor, paying special attention to the grout. Rinse with clear water and use towels, shop cloths, or a wet/dry vacuum to remove any excess water.

For older or heavily soiled grout, create a thick paste by mixing powdered oxygen bleach with warm water. Apply the paste to the grout, using an old toothbrush or wearing dish-washing gloves to protect your hands. Let the paste sit for five to 10 minutes, then scrub it with a grout brush.

It is advisable to wear knee pads or place a folded towel beneath your knees to prevent discomfort on the hard tile surface. To rinse the floor, mop it with clear water. However, this may not completely remove all traces of the oxygen bleach paste, so it is important to thoroughly wipe the floor with a clean, lint-free cloth dampened in clear water. Rinse or wring the cloth frequently while working.

How to Utilize a Machine for Cleaning Grout

Steam cleaners employ steam under pressure to effectively cleanse tile and grout. It is imperative to thoroughly read the instructions prior to adding any cleaner to the water in order to prevent any potential harm to the machine. Adhere to the manufacturer’s guidelines for filling and starting the machine, and then proceed to gradually move the steam cleaner’s wand across the floor, similar to the motion used when vacuuming a carpet. Be sure to focus on areas that experience heavy foot traffic. Allow the floor to completely dry before walking on it.
