How to Remove Grease from Kitchen Tiles and Splashbacks

Kitchen splashback tiles are the most grease-laden surface in the home. Every time you cook — particularly anything involving oil, butter, frying, or high-heat cooking — a fine mist of grease particles disperses into the air and settles on the nearest surfaces. The splashback, sitting directly behind the stove, catches the heaviest concentration.

The problem is that this grease buildup is largely invisible until it's significant. Fresh grease deposits are thin and shiny — you might not notice them until they've accumulated into a layer that feels tacky, dulls the tile surface, and has started trapping dust and cooking residue.

By the time most people clean their splashback, there are months of accumulated grease to deal with. Here's how to remove it properly.

Why Standard Wiping Doesn't Work

Grease is not water-soluble. Wiping a greasy tile with a damp cloth spreads the grease rather than removing it. You need:

1. A degreasing agent — something that emulsifies the grease (breaks it into small particles that can be rinsed away)
2. Dwell time — the degreaser needs time to penetrate and break down the grease layer
3. Mechanical action — wiping or scrubbing to physically lift the emulsified grease from the surface

All three components together produce results. Missing any one of them produces mediocre results.

Understanding Your Splashback Material

The right product depends on what you're cleaning.

Ceramic or porcelain tiles: The most common splashback material. Durable and chemical-resistant. Can handle most degreasers including alkaline cleaners and mild acidic products. Grout lines require specific attention.

Glass splashback: A single sheet of toughened glass or glass tiles. Non-porous, smooth and easy to clean — but shows streaks and smears clearly. Requires a streak-free approach after degreasing.

Natural stone tiles (marble, travertine, limestone): Acid-sensitive. Do NOT use vinegar, citric acid, or acidic degreasers on natural stone. Use only pH-neutral stone cleaners.

Subway tiles (glazed ceramic): Treat the same as ceramic tiles. The grout lines between subway tiles are a significant grease trap.

Stainless steel splashback: Clean with the grain using a degreaser, then wipe streak-free. Stainless steel shows fingerprints and smears very clearly.

Painted or rendered surfaces: Use gentler cleaning methods — avoid strong alkaline degreasers that can damage paint or render.

Method 1: Dish Soap Degreasing (Light to Moderate Buildup)

For splashbacks cleaned regularly (monthly or more often), dish soap at higher concentration than usual is effective.

Steps:

1. Mix several squirts of dish soap with warm water in a spray bottle — more soap than you'd use for dishes. The surfactants in dish soap are effective degreasers.

2. Spray generously onto the tile surface. Include the grout lines.

3. Leave for 5 minutes. Don't wipe immediately.

4. Scrub with a non-scratch sponge or cloth, paying particular attention to the grout lines (use a toothbrush or grout brush here).

5. Rinse with a clean damp cloth, wrung thoroughly. Multiple passes to remove all soap residue.

6. Dry with a clean microfibre cloth to prevent water marks.

Method 2: Commercial Kitchen Degreaser (Moderate to Heavy Buildup)

For splashbacks that haven't been properly degreased in several months, a dedicated kitchen degreaser is more effective than dish soap.

Products: Selleys Sugar Soap, Ajax Professional Kitchen Degreaser, or commercial-grade degreasers available at cleaning supply stores. These contain stronger alkaline agents that penetrate and emulsify accumulated grease more aggressively.

Steps:

1. Spray or apply the degreaser to the tile surface according to product instructions. For vertical surfaces like a splashback, hold a spray closer to the surface to reduce dripping.

2. Allow to dwell for the time specified on the product — usually 3–10 minutes. Don't let it dry.

3. Scrub with a non-scratch sponge or cloth. For heavy buildup, a medium-bristle brush produces better results than a cloth alone.

4. Rinse thoroughly — alkaline degreasers leave a residue if not fully rinsed, which can attract more grease faster.

5. Dry with a microfibre cloth.

For very heavy buildup: Apply degreaser, wrap cling film over the section to hold the product against the surface and prevent drying, and leave for 20–30 minutes. The extended dwell time softens even years of accumulated grease. Unwrap, scrub, rinse.

Method 3: Baking Soda Paste (Alternative Alkaline Option)

For anyone preferring to avoid commercial chemical degreasers, baking soda paste is an effective alternative for tile splashbacks (not for stone).

Mix baking soda with a small amount of dish soap and enough water to form a thick paste. Apply to the greasy tile surface. Leave for 10 minutes. Scrub with a sponge or cloth. Rinse thoroughly.

The baking soda provides mild abrasive action combined with alkaline chemistry — effective on moderate grease buildup.

Cleaning the Grout Lines

Grout is the biggest challenge on tile splashbacks. The porous, recessed grout lines trap grease, cooking residue and dust in a way that tile faces don't. Dark, greasy grout lines are the main visual indicator of a neglected splashback.

For light grease in grout: A toothbrush or grout brush with a concentrated dish soap solution, scrubbing along the grout line direction, removes most surface grease.

For heavy or stained grout: An alkaline grout cleaner applied to the grout lines, left to dwell for 10 minutes, then scrubbed with a stiff grout brush produces the best results. Commercial products like BAM Grout Cleaner or Aqua Mix Grout Cleaner are more effective than dish soap on heavily contaminated grout.

For mould in grout (common in the area directly above the stove due to steam): Diluted bleach (1:5 with water) applied to the grout lines, left for 10–15 minutes, then scrubbed and rinsed. Check first that your tile type tolerates bleach — most ceramic tiles do; some natural stone does not.

Cleaning Glass Splashbacks

Glass splashbacks are non-porous and easier to degrease than tiles, but require a streak-free finish.

1. Apply diluted dish soap or a glass-safe degreaser to the glass surface.
2. Wipe with a damp microfibre cloth.
3. Rinse with a clean damp cloth.
4. Dry immediately with a dry microfibre cloth using horizontal strokes.
5. Check from an angle in good light — any remaining streaks or smears will be visible. A final pass with a dry microfibre addresses these.

For stubborn grease on glass: apply a small amount of dish soap undiluted to the affected area, rub gently with a damp cloth, then rinse and dry streak-free.

Cleaning Stainless Steel Splashbacks

1. Apply a kitchen degreaser or diluted dish soap.
2. Wipe with the grain of the steel — never across it.
3. Rinse with a clean damp cloth, wiping with the grain.
4. Dry immediately with a dry microfibre cloth.
5. Optionally, apply a tiny amount of mineral oil on a dry cloth and buff with the grain for a polished finish.

Preventing Grease Buildup: The Most Effective Strategy

Wipe the splashback after every cooking session. Fresh grease wipes off in 30 seconds with a damp cloth. Week-old grease requires a degreaser and scrubbing. Month-old accumulated grease requires significant effort. The habit of a 30-second wipe after cooking dramatically reduces how often a thorough clean is needed.

Use lids and splash guards. Covering pots and using a splatter screen when frying dramatically reduces the grease that reaches the splashback.

Run the rangehood on high during cooking. A properly functioning rangehood extracts grease-laden vapour before it settles on surfaces. See our rangehood filter guide — a clogged filter means the rangehood isn't extracting effectively.
