Cleaning grout off a backsplash can seem like a daunting task, but with the right techniques and products, it can be accomplished effectively. Here are some tips on how to clean grout off a backsplash and restore its appearance.
Why Grout Gets Dirty
Grout is the material used between tiles on floors, walls, countertops, and backsplashes. It is usually a cement-based product that is porous and can trap dirt, grease, and grime over time. Discoloration of grout is common in kitchen backsplashes due to exposure to food splatters and spills. The porous nature of grout also means bacteria, mold, and mildew can grow if not cleaned properly. Keeping grout clean is important for sanitary and aesthetic reasons.
Gather the Proper Supplies
Having the right cleaning solutions and tools on hand will make the process easier. Here are some recommended supplies:
- Grout brush or old toothbrush – to scrub grout lines
- Grout steam cleaner – uses steam to loosen and sanitize grout
- Grout haze remover – removes film and residue from grout surfaces
- Non-sanded grout – for re-grouting if needed
- Grout sealer – to protect grout after cleaning
- Clean cloths and sponges
- Bucket
- Eye protection, gloves, and knee pads
Clean Surface Grout First
Before tackling the grout lines, start by cleaning the surface of the tiles and grout with an all-purpose cleaner or dish soap and water. This will remove any loose dirt or debris. Always use a soft cloth or sponge and avoid abrasive scrubbers. Rinse thoroughly and let dry completely.
Use a Grout Brush and Cleaner
Dip the grout brush in grout cleaner and work it along the grout lines in a circular motion. Let it sit for 5-10 minutes so the cleaner can penetrate and break up any grease or grime. Avoid getting cleaner on the tile surfaces. Scrub vigorously to loosen any embedded dirt. Rinse thoroughly with clean water. Repeat as needed for heavily soiled areas.
Try a Steam Cleaner
For grout that needs deep cleaning, use a grout steam cleaner. The steam helps sanitize as it loosens stubborn stains. Follow the manufacturer’s instructions. Focus the steam along grout lines and go slowly to fully penetrate the grout. Wipe with a clean cloth and rinse with water after steaming each area.
Use Grout Haze Remover
If your tiles have a whitish, filmy residue or grout haze on the surface, use a specially formulated grout haze remover. Apply it directly to the tile surface and let it sit for 5-10 minutes. The acidic formula dissolves mineral deposits and grout haze. Scrub gently with a stiff nylon brush. Rinse thoroughly with clean water.
Re-Grout If Necessary
For grout that is cracking, crumbling, or missing in spots, a more extensive fix is needed. Remove the old grout completely with a grout saw or rotary tool. Then re-grout the joints with non-sanded grout in a matching color. Wipe off excess grout and smooth the joints with a grout float.
Apply Grout Sealer
Once the grout lines are thoroughly cleaned and dried, apply a penetrating grout sealer. This will help protect the grout from future stains and damage. Carefully follow the product directions to ensure proper application. Re-apply yearly.
Grout Cleaning Tips
- Always pre-wet grout before cleaning to prevent absorbing more grime
- Acid-based cleaners can damage grout – test in an inconspicuous spot first
- Re-seal grout every 1-2 years for optimal protection
- Monitor backsplash grout lines for cracks or damage
- Clean spills quickly to prevent staining
Restoring dingy, stained grout on a backsplash takes some elbow grease but is a satisfying DIY project. With regular cleaning and sealing, your backsplash grout can look bright and new again. Be sure to use caution when working with grout cleaners and follow all safety precautions.
Frequently Asked Questions About Cleaning Grout Off Backsplash
How can I tell if my backsplash grout needs to be cleaned?
Signs that your backsplash grout needs cleaning include visible dirt, grime, or mold buildup; yellowing or discolored grout; cracks or missing grout; grout that feels gritty or rough; and grout lines that are no longer uniform in color when compared to the rest of the backsplash.
What is the easiest way to clean grout on a backsplash?
The easiest method is to use an all-purpose cleaner or dish soap and warm water with a grout brush or old toothbrush. Scrub gently along grout lines and rinse thoroughly. For deeper cleaning, use a steam cleaner or grout cleaner specifically designed to penetrate and dissolve buildup.
Should I use bleach or hydrogen peroxide to clean backsplash grout?
Bleach and hydrogen peroxide are not recommended for routine grout cleaning. They can be too harsh, strip color from grout, and damage the grout over time. For deep stain removal, hydrogen peroxide can be used cautiously in isolated areas. Test first and rinse thoroughly.
How can I get rid of mildew on my backsplash grout?
To remove mildew from grout, first scrub with a chlorine-based cleaner or oxygen bleach cleaner. Let it sit briefly before scrubbing. Rinse thoroughly and allow to fully dry. Apply a grout sealer to help prevent future mildew growth. Improving moisture control can also help.
Is it better to use sanded or unsanded grout on a backsplash?
Unsanded grout is preferred for backsplash installations. It is smoother, creates tighter joints between tiles, and resists cracking better. Sanded grout is coarser and better suited for floors or wider grout lines where added strength is needed.
How often should I reseal my backsplash grout?
Resealing backsplash grout every 1 to 2 years is recommended to maintain protection. High-traffic kitchen backsplashes may need sealing annually. Inspect sealant yearly – if grout is absorbing water or seems porous, it’s time to reseal. Always follow manufacturer instructions.
What is the white haze on my tiles after cleaning the grout?
Grout haze is a common issue after cleaning. It is a residue left behind on tile surfaces that leaves a whitish film. Use a grout haze remover or diluted white vinegar to dissolve the haze. Agitate with a nylon brush and rinse thoroughly with water.
Cleaning and restoring dirty grout on a backsplash takes effort, but is a budget-friendly alternative to re-tiling. With the right techniques and regular sealing, your backsplash can look fresh again. Always test cleaning methods in inconspicuous areas first. If stains persist, professional regrouting may be needed.
Conclusion
Cleaning grout off a backsplash helps restore the appearance and sanitize kitchen surfaces. With periodic cleaning using brushes, steam, and specialized cleaners, grout can be refreshed and maintained. Resealing protects grout from future staining. Taking time to properly clean and seal backsplash grout pays off with great looking results and improved kitchen hygiene. A clean backsplash improves the look of any kitchen.
