For a grease burn, the first thing to reach for is cool running water. Hold the burned area under cool (not cold) tap water for about 10 minutes to draw heat out of the skin and limit the damage. After cooling, a thin layer of antibiotic ointment and a non-stick bandage are the standard treatment for most minor grease burns you can handle at home.
Cool the Burn Immediately
Hot grease clings to skin and keeps burning even after the splatter, so your first priority is removing any grease-soaked clothing and getting cool water on the area. Run cool tap water over the burn for a full 10 minutes. This does more than ease pain; it actually reduces the depth of the injury by pulling residual heat out of the tissue.
Use cool water, not cold, and never use ice. Ice and ice water restrict blood flow to the burned area and can numb the skin so much that you can’t tell when the tissue is getting too cold. Leaving ice on a burn can cause frostnip, permanently impair circulation, increase your infection risk, and make the injury worse overall. Plain cool tap water is the single most effective first step.
What to Put on a Grease Burn After Cooling
Once the burn is cooled and gently cleaned, apply a thin layer of an over-the-counter antibiotic ointment like Polysporin or a similar combination antibiotic product. This keeps the wound moist, which helps new skin grow faster, and provides a barrier against bacteria. Petroleum jelly (like Vaseline) is also a reasonable option if you don’t have antibiotic ointment on hand.
After applying ointment, cover the burn with a non-stick (nonadherent) dressing or fine mesh gauze. Regular cotton gauze or adhesive bandages can stick to the raw wound surface, causing pain and tearing new skin when you change them. Non-stick pads are available at any pharmacy and are worth having in a first aid kit.
Change the dressing regularly, typically once or twice a day for burns that are still oozing. When you change it, gently clean the area with mild soap and water, pat dry, reapply ointment, and cover with a fresh bandage. Avoid scrubbing the wound during dressing changes. Being rough with a healing burn is painful and can slow recovery.
What Not to Put on a Grease Burn
Butter, cooking oil, toothpaste, and egg whites are common home remedies that all make burns worse. Butter and oil trap heat in the skin, extending the burn deeper. Toothpaste contains chemicals that irritate raw tissue. None of these are sterile, so they introduce bacteria directly into an open wound.
Cold water, ice packs, and frozen food from the freezer fall into the same category. They feel like they should help, but they constrict blood vessels and can cause tissue damage on top of the burn. Stick with cool, not cold.
Managing Pain at Home
Grease burns hurt, sometimes for days. Over-the-counter pain relievers like ibuprofen (Advil, Motrin), acetaminophen (Tylenol), or naproxen (Aleve) all work. Ibuprofen and naproxen also reduce inflammation, which can help with swelling around the burn. Follow the dosing instructions on the bottle, and don’t give aspirin to anyone under 19.
Keeping the burn covered and moist also helps with pain. Exposed burns dry out and crack, which triggers more nerve irritation. A properly dressed burn with ointment underneath is noticeably less painful than one left open to the air.
How to Tell if Your Burn Needs Medical Attention
Most grease burns from cooking are small, superficial, and heal on their own within one to three weeks. But grease burns can be deceptively deep because hot oil reaches temperatures well above boiling water.
A first-degree burn (like a mild sunburn) turns red and hurts but doesn’t blister. These heal in about a week with basic home care. A second-degree burn goes deeper, blisters, looks wet or shiny, and is intensely painful. Small second-degree burns can still be treated at home, but larger ones or those in certain locations need professional care. A third-degree burn looks white, brown, or leathery and may not hurt much because the nerves are damaged. This always requires medical treatment.
Get to a doctor or emergency room if your grease burn:
- Covers a large area, roughly bigger than three inches across or wrapping around a limb
- Involves the face, hands, feet, or joints, where scarring or tightening skin can cause functional problems
- Blisters extensively or appears white, waxy, or charred
- Happened to a child under 10 or an adult over 50, who are more vulnerable to burn complications
Signs of Infection to Watch For
Even a well-treated burn can get infected, and an infected burn needs medical attention. Watch for increasing redness spreading beyond the edges of the burn, pus or foul-smelling drainage, red streaks radiating outward from the wound, or a fever. Mild redness right around the burn edges during the first day or two is normal inflammation. What you’re watching for is redness that gets worse after the first 48 hours or starts spreading, which signals that bacteria have taken hold.
If you notice any of these signs, see a healthcare provider. Infected burns sometimes need prescription-strength topical treatments or oral antibiotics, and delaying treatment can lead to scarring or more serious complications.
