How to Remove Grease from Backsplash Grout

Kitchen backsplashes are prone to grease buildup over time, especially around the grout lines. Grease stains not only look unsightly but can also attract dirt and bacteria. Removing grease from grout requires some elbow grease, but it can be done using common household ingredients. Here are some effective methods for how to remove grease from backsplash grout.

What Causes Grease Buildup on Grout?

When cooking, tiny grease particles float in the air and settle on kitchen surfaces. Over time, these particles accumulate in the porous grout lines. Grease sticks strongly to grout and resists casual cleaning methods. Several factors make grout prone to grease buildup:

  • Porous nature – Grout is porous and absorbs grease easily. The texture grabs and holds onto grease.
  • Surface area – Backsplashes have extensive grout lines that provide ample surface area for grease to cling.
  • Cooking methods – Frying and sautéing release airborne grease that readily sticks to backsplashes. High heat and oil splatter worsen buildup.
  • Infrequent cleaning – Grease accumulates faster when backsplashes aren’t cleaned regularly before buildup gets worse.

How to Remove Existing Grease Stains from Grout

Removing existing grease stains and discoloration requires deep cleaning. Start with milder homemade cleaners before attempting heavier-duty store-bought options.

Baking Soda Paste

Baking soda is mildly abrasive and helps lift grease when made into a paste.

How to:

  1. Make a paste of 3 parts baking soda to 1 part water. Adjust consistency as needed.
  2. Apply paste to stained grout lines using an old toothbrush or cotton swab.
  3. Let sit for 5-10 minutes. Gently scrub while paste is still moist.
  4. Rinse thoroughly and pat dry. Repeat if needed.

Vinegar Solution

Vinegar helps dissolve grease and cuts through grime. Create a cleaning solution of equal parts vinegar and warm water. Use a spray bottle for easiest application. Let the solution sit for 3-5 minutes before scrubbing with a stiff nylon brush. Rinse thoroughly. For tougher stains, repeat and let the vinegar solution sit longer before scrubbing.

Dish Soap and Water

Dish soap combined with warm water can effectively penetration grease and lift stains from grout.


  1. Mix a few drops of dish soap with warm water in a spray bottle.
  2. Lightly spray stained grout and let sit briefly.
  3. Scrub using an old toothbrush, cotton swab or sponge.
  4. Wipe clean and rinse thoroughly. Repeat for heavier staining.

Hydrogen Peroxide

Hydrogen peroxide is a mild bleach that breaks down grime. Create a paste by mixing equal parts hydrogen peroxide and baking soda. Apply to stained grout and let sit for 10 minutes before scrubbing and rinsing. Hydrogen peroxide can help lift stubborn grease stains.

Commercial Grout Cleaners

For severe grease staining, a commercial tile and grout cleaner may be necessary. Look for options containing surfactants, detergents or bleach for cutting through grease. Carefully follow product label instructions. Rinse surfaces thoroughly after cleaning.

Tips for Preventing Grease Buildup on Grout

Prevention is key for keeping grout grease-free long-term. Here are some helpful tips:

  • Wipe down backsplashes after cooking using a hot, soapy sponge. This prevents grease residue from sticking.
  • Use stove ventilation hoods when cooking to reduce airborne grease exposure. Keep exhaust fans and filters clean.
  • Clean backsplashes regularly using mild dish soap, vinegar solution, or appropriate tile cleaners. Frequent cleaning prevents heavy staining.
  • Seal grout annually with a penetrating sealer which protects the porous surface from absorbing grease and makes cleaning easier.
  • Replace frequently used kitchen sponges often to prevent spreading grease during surface cleaning.
  • Adjust cooking techniques by reducing heat, oil and grease when possible to minimize backsplash exposure.

Frequently Asked Questions About Removing Grease from Grout

What is the fastest way to remove grease from grout?

For quick grease removal, spray greased grout with a degreasing agent like Windex or diluted dish soap. Let it soak briefly then scrub with a stiff brush before rinsing. The chemicals in these products cut through grease quickly.

What household product removes grease from grout?

Common household products effective for removing grease include baking soda, vinegar, hydrogen peroxide, lemon juice and dish soap. Make pastes or solutions and allow to soak into the grout before scrubbing. The acids and abrasives in these products dissolve and lift grease.

Does bleach remove grease from grout?

Yes, bleach can help remove sticky grease buildup from grout. Make a paste of baking soda and bleach and apply to stained grout. Let it sit for 5-10 minutes before scrubbing and rinsing. Be very careful using bleach products and never mix bleach with vinegar or ammonia.

What is the best homemade grout cleaner?

The best homemade grout cleaner is either a baking soda paste or a solution of vinegar and water. Baking soda lifts and absorbs grease while vinegar cuts through grime. For heavy duty cleaning, make a paste using hydrogen peroxide and baking soda to really tackle grease stains.

What should you not use to clean grout?

Avoid using harsh chemicals like ammonia or industrial strength cleaners on grout, as they can damage and discolor the grout over time. Stay away from oil-based products like mineral oils or citrus oils, as they will only attract more dirt. Acidic products like lemon juice should be used sparingly, as they can wear down grout when used frequently.


With regular upkeep and prompt spot treatment, it is possible to keep backsplash grout free of grease buildup. Using mild cleaners like baking soda, vinegar and dish soap can safely tackle grimy grout. For prevention, wipe down backsplashes after cooking and install range hoods. Annually sealing grout also buffers against grease absorption. With some consistent elbow grease, your white grout lines can stay pristine and grease-free.
