The best thing? It’s much easier than you think. So, without further ado, here’s how you can clean bathroom grout and tiles.

How to Clean Bathroom Grout and Tiles?

Here is a comprehensive breakdown of how you can make your bathroom grout and tiles brand new again!

Step #1 – Clean the Tiles

For many bathroom tiles, a DIY tile cleaner comprising dish soap and warm water is enough to do the trick. This mixture is equally effective for ceramic and porcelain tiles.

Many times, diluted vinegar is also recommended to clean bathroom tiles.

However, according to a technical trainer at the National Tile Contractors Association, Rob Roderick, vinegar is highly acidic.

In case the vinegar solution is too strong, it can etch stone tiles. Moreover, a concentrated vinegar mixture can even damage and weaken the grout.

Hence, the best way to proceed is to spray a solution of dish soap and water on the bathroom tiles. Then, wipe away the tiles using a damp cloth or microfiber towel.

However, liquid dish soap and water solutions might not always give you the desired results. In such a case, you can use the following DIY tricks to clean up your bathroom tiles.

1. Use a Baking Soda Cleaner

Mix ¼ cup of hydrogen peroxide with ½ cup of baking soda and one teaspoon of liquid dish soap.

Pour the solution into a spray bottle and spray it on the dirty bathroom tiles.

Let the solution sit on the tiles for 10 to 15 minutes. After that, wipe the tiles off using a damp rag or sponge.

2. Use a Mixture of Water and Bleach

Mix three parts of water to one part bleach to prepare an effective tile-cleaning solution. For instance, you can combine twelve tablespoons of water with four tablespoons of bleach.

Add the mixture to a spray bottle and spray it on the bathroom tiles. Dampen a cloth with warm water and use it to wipe the tiles clean.

Practice extreme care when using this mixture to clean up the tiles. For instance, bleach emits harmful fumes.

Hence, you should open windows and doors before starting to prevent the buildup of fumes.

Moreover, bleach can even irritate your skin. Thus, make sure to wear thick rubber gloves while cleaning your bathroom tile with it.

3. Use Ammonia

Add 1 part ammonia to 2 parts of water. For instance, you can combine four tablespoons of ammonia with eight tablespoons of water.

Fill a spray bottle with the ammonia solution and spray it on the bathroom tiles.

Allow the mixture to sit on the tiles for around an hour. Then, use a clean, moist cloth to wipe it away.

Keep in mind that ammonia can also emit dangerous fumes. Hence, make sure your bathroom is well-ventilated as you clean your tiles with this solution.

4. Use A Hydrogen-Peroxide Paste

A hydrogen peroxide paste is a bit on the heavier side. Therefore, you should only use it when all your other DIY cleaning techniques fail to work.

Here’s how you can clean your bathroom tiles with hydrogen peroxide. Mix equal parts of all-purpose flour and hydrogen peroxide to make a thick paste.

Apply the paste onto the bathroom tiles you wish to clean. Cover the area using cellophane and let the paste sit overnight.

Then scrub off the tiles using a tile-cleaning brush.

Step #2 – Use A Steam Cleaning Machine to Scrub the Tiles

In the bathroom, you aren’t just dealing with surface dirt and debris. Instead, you also need to eliminate soap scum residue, which is much difficult to get rid of.

Here, a steam cleaning machine comes to the rescue! Steam cleaning is an excellent cleaning technique if you suffer from allergies to chemicals and mold.

To clean your bathroom tiles with a steam cleaner, start by fixing a small brush into the steaming lance.

Then, steam a line onto the tiles. As you move along, gently scrub with the brush. You will notice the dirt and residue coming off easily.

Lastly, use a microfiber cloth to wipe clean the tiles.

Step #3 – Start Working on the Grout

Once you have cleaned your tiles, it’s time to shift your focus to the grimy grout lines.

How grimy your grout gets essentially depends on what it’s made of. Usually, grout is a combination of cement and sand.

However, more contemporary ones even include latex and other polymers to enhance their stain-resistance power.

Regardless of what stains you’re dealing with, water and patience will be your two best allies. Start off by spraying hot water onto the grout.

Next, scrub the grout using a grout brush or a stiff bristle brush to remove any grime or dirt on the surface.

A steam cleaner is also highly effective in this stage too. Simply apply steam directly onto the grout.

Then, use a clean rag to blot away any remaining moisture. After the grout dries up, the grout will appear as good as new.

Step #4 – Remove Stubborn Grout Stains

If your grout still isn’t clean, you can use a pH-neutral cleaner to clean the grout further. For instance, the Neu’s Tub & Tile Cleaner is one product that you can opt for.

Next, get a stiff brush and scrub the grout stains again.

According to Donna Smallin Kuper, author at and certified house cleaning technician, “Elbow grease really is the most important ingredient.”

Moreover, a Magic Eraser can also effectively remove stubborn stains. However, keep in mind that you might need more than one to clean up your bathroom tiles.

After you have thoroughly scrubbed, use a microfiber cloth or a damp sponge to eliminate any grout cleaner residue.

Make sure to use fresh water and a clean cloth. If the cloth is dirty, or you use unclean mop water for rinsing, the grout will soak it up and become discolored again.

For highly stubborn spots, the Tile Council of America suggests you use alkaline cleaners rather than acidic ones. For instance, you can opt for Spic and Span or Mr. Clean.

If you are going with a cleaner that doesn’t have a neutral pH, you should first do a quick patch test in a small area.

Wait for a couple of minutes to ensure there’s no damage or discoloration before you move on to clean the remaining grout tiles.

Step #5 – Get Rid of Mold

Humid, hot bathrooms with poor ventilation are perfect environments for mold spores.

Bleach does successfully eliminate mold on non-porous surfaces, such as countertops and tiles.

However, it’s not that helpful on porous surfaces, such as grout, drywall, caulk, and wood.

A great option is to invest in the Zep Tile Mold Stain and Mildew Stain Remover and eliminate mold spots for good.

Also, make it a habit to turn on the bathroom fan or open a window after taking a shower. This helps to keep the humidity levels in check.

Step #6 – Seal Up Your Success

In this step, use sealers to fill the grout’s pores. This helps to prevent mold, grime, and grit from penetrating the porous materials.

The frequency with which you need to seal grout depends on how much traffic your bathroom gets. Nevertheless, you should do it at least once every year.

Also, wait for at least 24 hours between deep-cleaning the grout and applying the sealer.

This way, you can ensure that the grout has dried up completely.

One excellent product that you can buy for this purpose is DuPont Grout Sealer.

Step #7 – Make Some Changes

In your bathroom, you might notice that some areas are particularly dirty. For instance, near the laundry basket or by the back door.

In these areas, you can place a rug to protect them from debris and dirt. You can even sweep and mop more frequently to prevent dirt buildup on the tiles and grout.

Last Few Words

There are several things you can do to cut down future grout-cleaning time by half.

For instance, keep a clean microfiber cloth or a small squeegee near the shower to immediately wipe away the tiles and grout after taking a shower.

This will eliminate the need for deep cleaning in the future as there won’t be any new buildup on the surface of the tiles.

In addition, you can ask your family members to switch on the exhaust fan for 15 to 20 minutes after taking a shower.

Doing this will help to reduce moisture and humidity from your bathroom. It also helps to prevent mold growth on the grout.
