It’s the enemy of a clean kitchen – that sticky film near your stove that coats cabinets, backsplashes, and the range hood. When a simple wipe doesn’t touch it, you don’t have to trade clean air for harsh solvents. Use the right chemistry and you can cut through it safely.

The science of grease – why vinegar falls short

Grease is a lipid. Acids like vinegar shine on alkaline messes (think hard-water deposits), but they aren’t the best tool for oils. To remove grease you need surfactants – molecules with a water-loving head and oil-loving tail that form micelles around oils so they rinse away with water (American Cleaning Institute; Yale Medicine).

The Two-Step Method for Natural Grease Removal

Step 1 – Alkaline scrub (break the tough outer layer)

• Mix baking soda with a little warm water to make a thick paste.
• Spread on caked, sticky spots. Wait 5–10 minutes.
• Scrub with a damp, non-scratch sponge and wipe away the dirty paste.

Step 2 – Surfactant wash (lift and remove the grease)

• Add a good squirt of gentle, non-toxic dish soap to a bowl of hot water and agitate to make suds.
• Wash surfaces with a damp cloth, rinsing and repeating on very sticky areas.
• Rinse with clean water, then buff dry for a streak-free finish.

The Green Llama way

Soap + water works, but can leave residue. Our All-Purpose Cleaner uses high-performance, plant-based surfactants to cut grease and rinse clean – the perfect follow-up after the baking-soda step.

Quick FAQs

How do I clean the greasy range-hood filter? Soak the metal mesh in very hot water with a generous squirt of degreasing dish soap for ~30 minutes, scrub, rinse, and dry fully before reinstalling.

Can I just use an orange-based cleaner? Citrus solvent (d-limonene) cuts grease well, but it can irritate skin or airways in some people – ventilate and follow labels (NOAA CAMEO; EPA; WHO IPCS).

Why not vinegar for baked-on grease? It isn’t ideal for lipids. Save vinegar for mineral scale and glass; use heat + surfactants for grease removal (ACI).
