How to Clean White Grout Backsplash

Having a white grout backsplash can look absolutely stunning in your kitchen or bathroom. However, it does require some regular cleaning and maintenance to keep it looking its best. Over time, grout can absorb stains and appear dingy. With the right techniques and products, you can have your white grout backsplash looking like new again.

Why White Grout Gets Dirty

White grout is prone to getting dirty for a few reasons:

  • Grout is porous, so it easily absorbs any spills, grease splatters, or dirt. This is especially true with lighter colored grout.
  • It’s textured, so debris, soap scum, and hard water deposits can get caught in the grout lines.
  • It’s located in areas that tend to get splashed and exposed to grime, like behind sinks and stoves.

Regular cleaning is necessary to prevent buildup and keep grout bright white.

Supplies Needed

Cleaning white grout backsplash doesn’t require any harsh chemicals. You can brighten it up with common household items:

  • Baking soda
  • White vinegar
  • Spray bottle filled with water
  • Old toothbrush or grout brush
  • Clean cloths or sponges

Optional extras include hydrogen peroxide, a grout pen, and protective sealants.

Routine Maintenance

Get into a regular grout cleaning routine to prevent major buildup:

  • Sweep or vacuum the backsplash weekly to remove loose dirt and debris. Pay extra attention to grout lines.
  • Spot clean spills and splatters as soon as they happen. This prevents staining.
  • Wipe down the backsplash with a damp microfiber cloth and mild soap as part of your regular kitchen cleaning.
  • Clean grout lines thoroughly once a month with a toothbrush and baking soda paste.

Deep Cleaning Methods

For grout that needs more intense cleaning, use one of these methods:

Baking Soda and Vinegar

Make a paste with 3 parts baking soda to 1 part water. Apply to grout lines and let sit 5-10 minutes. Spray white vinegar over the paste and scrub with a grout brush. Rinse thoroughly. The combination of baking soda and vinegar will break up grime and whiten the grout.

Hydrogen Peroxide

Mix equal parts hydrogen peroxide and water in a spray bottle. Lightly spray on grout and let sit for 5 minutes. Scrub and rinse. The peroxide will help brighten and disinfect.

Commercial Grout Cleaners

Look for cleaners made specifically for grout at your local home improvement store. Apply as directed. These often contain bleach or other chemicals to penetrate tough stains.

Steam Cleaners

A steam cleaner uses high heat to clean and sanitize grout. Steam loosens dirt so you can wipe it away easily. Use the narrow attachments to direct steam right into grout lines.

Grout Pens

For small spots or grout lines in good overall condition, a grout pen can whiten and cover stains. Simply apply like a marker. This doesn’t fix cracks or damage.

Tips for Cleaning White Grout Backsplash

Follow these tips for the best grout cleaning results:

  • Always do a test spot first, especially with harsher cleaning products.
  • Apply any pastes or sprays directly to grout lines, not the tiles. Avoid getting tiles wet whenever possible.
  • Use a stiff grout brush or old toothbrush to scrub. Soft bristles won’t cut through buildup.
  • Rinse thoroughly after cleaning. Any residue left behind can attract more dirt.
  • Change rinse water frequently to prevent redepositing grime back on the grout.
  • Be patient with layered stains or mold. It may take several applications and scrub sessions.
  • Consider re-sealing your grout every 1-2 years to protect from future staining.

Common Grout Backsplash Cleaning Questions

How do I get grease stains off my white grout backsplash?

Mix baking soda and dish soap into a spreadable paste. Apply to the stains and let sit for 10-15 minutes before scrubbing clean. The baking soda will absorb and cut through the grease.

What about soap scum or hard water buildup on grout?

Use an equal mix of white vinegar and water to dissolve mineral deposits and soap scum. Spray or wipe on generously and let sit for 5-10 minutes before scrubbing and rinsing. The acetic acid in vinegar cuts through alkaline buildup.

My grout has some cracks and damaged areas. Can I still get it white again?

Focus on cleaning the intact grout first. For cracks and missing grout, you’ll need to re-grout those areas after cleaning for an even look. Damaged grout is more prone to collecting dirt in the future.

How can I get mold off my grout lines?

Mix one part hydrogen peroxide with one part water and spray on the moldy areas. Let it sit 10 minutes before scrubbing with a stiff grout brush. Repeat as needed. The hydrogen peroxide will kill mold and brighten the grout. Ensure the area can dry well to prevent mold recurrence.

Is there a good daily grout cleaner I can use?

For routine grout line cleaning, wipe down with either a 50/50 vinegar and water solution or a mild bleach-based spray cleaner. Avoid harsh, acidic daily cleaners, as they can damage grout over time.


With consistent cleaning and maintenance, you can keep your white grout backsplash looking freshly installed. Use a combination of routine wiping, monthly scrub sessions, and occasional deep cleaning as needed. Always rinse thoroughly and allow proper drying time. Protect your pristine grout by sealing it annually. With a little work, your white grout backsplash will maintain its bright, clean appearance.
