How to Remove Kitchen Grease Buildup

Tap a step to see it in order.

  1. Understand why alkaline cleaners break down grease

    Baking soda and washing soda (or oxygen-based alkaline cleaners) react with grease in a mild soap-making reaction called saponification, turning stubborn, hardened grease into a form that rinses away in water instead of clinging to the surface.

  2. Soak a range hood filter before scrubbing it

    Remove the range hood filter and let it soak in warm water mixed with an oxygen-based alkaline cleaner for 20-30 minutes. The hardened grease softens enough that a brush lifts it off with very little scrubbing.

  3. Clean stovetop burners with a baking soda paste

    Remove the burner caps, spread a thick baking soda and water paste over them, let it sit, then scrub with an old toothbrush to reach the grooves. This lifts baked-on food and grease without scratching the metal.

  4. Use gentler tools on induction and glass cooktops

    Induction and glass cooktop surfaces scratch easily, so stick to a cleaner made for the surface and a soft sponge, and skip abrasive scouring pads entirely.

  5. Reapply cleaner in rounds for heavily built-up grease

    Grease that has built up over months rarely lifts in a single pass. Applying cleaner, wiping, and reapplying two or three times removes it gradually without needing to scrub hard enough to damage the surface.

  6. Finish with a dry cloth after rinsing

    Rinsing off all cleaner residue and then wiping the surface dry with a clean cloth prevents streaking and stops any leftover residue from attracting new grime.

The real mechanism is saponification, not elbow grease

Grease clings to a surface because it is not water-soluble on its own. An alkaline cleaner chemically converts it into a soap-like substance that water can carry away, which is why letting the cleaner sit for a few minutes works better than scrubbing harder the moment it is sprayed on.

Match the cleaner to the surface, not just the mess

A cast-iron burner grate and a glass induction top need completely different amounts of abrasiveness even when they are equally greasy. Checking what a surface can tolerate before choosing a cleaner or scrub pad avoids trading a grease problem for a scratched-surface problem.

Frequently Asked Questions

Which works better on grease, baking soda or washing soda?

Baking soda is fine for light, everyday grease, but washing soda (or an oxygen-based alkaline cleaner) is more strongly alkaline and works better on heavily built-up grease, like a range hood filter that has not been cleaned in months.

What should I do if the grease will not come off after cleaning once?

Do not scrub harder. Reapply the cleaner and repeat the soak-and-wipe process a few times instead. Repeated gentle applications remove stubborn grease without risking scratches.
