Revitalizing grout is a rewarding task that can dramatically refresh your bathroom without costing a dime.
Whether your shower grout has developed an unpleasant orange hue from shampoo residue or your floor tiles need attention, we've got the solutions.
Here are some top-notch grout cleaning techniques recommended by experts, suitable for both light and deep stains, along with preventative tips that can help keep mold and mildew at bay, making your next bathroom cleaning easier.
Effective Grout Cleaning Strategies
While tiles are simple to maintain, grout poses challenges due to its porous nature, making it susceptible to stains. Bathrooms, with their humid environment, are particularly prone to mold growth, which can discolor grout.

1. Tackling Light Stains
Warm Soapy Water Scrub
For minor stains, cleaning the grout might just require warm water. If it's not sufficient, mix water with dish soap, using a microfiber cloth from Amazon or a mop for floor tiles.
If that doesn't do the trick, an old toothbrush or a sturdy grout brush from Amazon can effectively scrub along the grout lines. Rinse with hot water to eliminate any leftover residue.
2. Addressing Deep Stains
Using The Pink Stuff
For tougher stains, consider an alkaline cleaner, like The Pink Stuff from Amazon, along with a stiff brush. This method is a favorite for many due to its effectiveness. Apply a small amount of the paste with an old toothbrush, rinse with cold water, and wipe dry with a clean towel. This technique lifts stains and brightens grout lines.
There are also specialized grout cleaners available, including Grout Eez. Always rinse thoroughly, whether tackling mold in the shower or around sinks.
An electric scrubber can also be an excellent investment for achieving sparkling tiles and grout.

Consider a Drill Bit or Shop Vac
If you're seeking a more effortless solution, consider using a drill bit brush from Walmart. This tool performs a superior job of scrubbing grout compared to manual methods.
For those with a shop vac, this can be an effective method for cleaning grout on floor tiles. Apply an alkaline cleaner as directed, then use the shop vac to remove dirty water. This not only eliminates water but also extracts dirt from the grout.
After rinsing, use the vac again to ensure no soap residue is left behind.
Specialized Mold Removers
Mold often thrives in bathroom moisture and typically appears on grout. If you still see black spots after cleaning, a mold remover designed for grout is necessary.
Be cautious with bleach, as it can discolor and weaken grout over time. If you choose to use bleach, dilute it with water and apply sparingly. Alternatively, hydrogen peroxide is a safer, more effective option.

Preventative Strategies
Reducing moisture in your bathroom can help prevent stains and the need for extensive mold removal. Wipe down tiles after showers with a towel or squeegee, and ensure proper ventilation by opening windows or using one of the best dehumidifiers. This also helps deter silverfish, which thrive in moisture.
Common Questions
How can I restore the whiteness of grout?
To bring grout back to its original color, create a paste with baking soda and water, then gently scrub it into the grout with a toothbrush. Spraying white vinegar over the paste will create a bubbling reaction that helps lift dirt.
What do professionals use for cleaning grout?
Professional cleaners typically inspect the grout, pre-spray heavily stained areas, and utilize high-pressure hot water cleaning to remove dirt. After rinsing, they often apply a sealer to protect the grout from spills and stains in the future.
Does vinegar damage grout?
Using vinegar on grout is not advisable since it contains acids that can dissolve cement. This may weaken the grout and harm stone tiles. Instead, opt for alkaline cleaners, as recommended by experts.
How to clean grout without damaging tiles?
Steam cleaning is a gentle method for cleaning grout. It uses high-temperature steam to loosen dirt and bacteria, requiring minimal scrubbing.
Don't delay in addressing dirty grout. If it becomes unmanageable, you might consider regrouting your tiles.
