Over time, your gas stove inevitably accumulates layers of grease, grime, and even rust—dulling its appearance and reducing its lifespan. As the Vietnamese lifestyle site Tạp Chí Đời Sống points out, these stubborn stains not only detract from the kitchen’s look but also risk damaging the appliance if left unattended.

Here’s a more detailed, polished version, supplemented with scientific reasoning and professional advice:

The Problem: Rust, Grease & Fading Finish

A gas stove’s surface is constantly exposed to oil splatters, heat, spills, and moisture. Over time:

• Rust forms when metal is exposed to moisture and air; heat accelerates oxidation.

• Grease and carbon buildup adhere to surfaces, forming hardened, sticky layers that trap dirt.

• Finish degradation (fading or discoloration) may occur, especially on stainless or painted parts.

Removing these requires both chemical methods and gentle abrasion—without damaging the stove metal or parts.

Four Natural Cleaning Methods & Why They Work

The original article offers four key steps using common household materials. Below is that guidance, enriched with rationale and tips:

1. White Vinegar — “Weapon” Against Rust and Grease

White vinegar is often the first go-to. Its mild acetic acid can dissolve mineral and grease deposits and help loosen rust patches.

Method:

• Pour or spray vinegar directly onto rusted or greasy areas.

• Let it sit for 10–15 minutes to allow it to penetrate.

• Use a soft brush or non-scratch scrub pad to gently rub the area.

• Wipe clean with water, then dry with a cloth.

Why it helps: The acid breaks the bonds that hold rust and grease to metal surfaces. Using it before scrubbing reduces friction and risk of scratching.
Tip: Warm the vinegar slightly for stronger effect—just don’t boil it on the stove.

2. Baking Soda — the Finisher

Baking soda is a mild abrasive and base. It neutralizes the acid of vinegar and helps scrub away loosened grime.

Method:

• Mix baking soda with just enough water to make a thick paste.

• Spread it over stained areas.

• Using circular motions, scrub gently with a sponge or soft brush.

• For extra cleaning power, first spray vinegar, then sprinkle baking soda—let fizz, then scrub.

• Finally, rinse and dry.

Why it helps: The paste gently scrapes residual grime while reacting with residual acid to further dislodge deposits.

3. Lemon Juice — Natural Cleaner with Fresh Scent

Lemon contains citric acid, which is similar to vinegar in function but with a pleasant fragrance.

Method:

• Squeeze fresh lemon juice; dilute slightly with warm water.

• You can sprinkle salt onto stubborn spots and rub with half a lemon.

• Leave for a few minutes, then scrub gently.

• Rinse and wipe dry.

Why it helps: The acidity attacks grease and oxidation. The salt introduces a mild abrasive effect when combined with lemon flesh.

4. Preventive Protection — After Cleaning

Cleaning is only half the job. The article emphasizes the importance of aftercare to delay rust re-forming.

Steps:

• After scrubbing, wipe the stove with a damp cloth to remove residues, then thoroughly dry.

• Optionally, apply a thin coat of cooking oil (e.g., vegetable or canola) onto metal parts and wipe off excess. This forms a protective film.

• Regularly wipe up spills immediately—especially oily or acidic ones—to avoid buildup.

• Clean knobs, crevices, and burner parts frequently, where grease often lurks. (Tap Chí Đời Sống)

What Cleaning Experts & Metal Care Sources Advise

• Many cleaning and home-improvement publications (like Good Housekeeping and This Old House) recommend the same vinegar + baking soda combination as a safe, effective method for household metal and stainless appliances.

• Professional appliance repair technicians warn against harsh oils or cleansers containing chlorine (bleach) or high acids, which can erode stainless steel or painted finishes over time.

• In corrosion science, protective oil films are a recognized mitigation for oxidation—thin layers of oil slow down exposure to moisture and air.

• Abrasive steel wool or harsh metal brushes, while effective, may scratch or damage coatings — always use gentle brushes or scouring pads rated safe for stainless/metal surfaces.

Extra Tips & Safety Warnings

• Always disconnect or turn off gas supply before cleaning burner areas to prevent accidental ignition.

• Avoid excessive water on ignition ports or control knobs. Use towels to keep water away from electrical/gas components.

• Test methods in a small, inconspicuous area first to ensure no discoloration or damage.

• Use rubber gloves to protect your skin from prolonged exposure to acid or alkaline cleaners.

• Ventilate the kitchen while cleaning to evaporate fumes from vinegar, lemon, etc.

• For stubborn rust that resists these natural methods, consider commercial rust removers formulated for kitchen appliances—use carefully and follow manufacturer instructions.
