As a home cook with years of experience frying foods in oil or butter, I've dealt with oil splatters everywhere around my gas stove. These grease stains are notoriously stubborn, especially if not addressed right away.
From afar, my kitchen looks spotless:

But up close, the truth emerges. Check out those tiny splashes on the air vent above my microwave—they're all oil splatters.

They appear every time I pan-fry. The worst buildup is on top of the microwave, where oil mixes with dust to form a tough, grimy layer.

When you wipe it with a paper towel, the oil and dust clump into sticky mess:

Thankfully, I've discovered a reliable, chemist-approved method to dissolve these splatters effortlessly using mineral oil.

1. Apply 2-3 drops of mineral oil to a paper towel.
2. Wipe the stained surface—the grime lifts away like magic.

3. Finish by buffing with a clean, dry paper towel. This leaves a protective mineral oil film, making future cleanups even easier.

Surfaces now gleam clean and fresh. No more scrubbing with soapy water—this trick lets dirt wipe away effortlessly.
Mineral oil, a neutral protectant commonly used on wood like cutting boards, excels here. Vegetable oil works short-term too.
But a chemist friend explained the long-term advantage: "Both oils dissolve splatters due to their greasy nature. However, mineral oil doesn't yellow, oxidize, or turn sticky over time—unlike vegetable oils rich in unsaturated fatty acids that degrade when exposed to air."
