Not Just for Cooking: Why Some Drivers Keep Cooking Oil in the Glove Box

At first glance, ordinary cooking oil might seem to have little to do with cars. But some drivers keep a small bottle in the glove box for situations when a specialized product isn't readily available. From freshening up interior surfaces to removing stubborn adhesive residue, cooking oil can be useful for a handful of simple car-care tricks.

Experienced drivers sometimes use vegetable oil for more than interior care. It can also help loosen sticker residue, provide temporary protection against moisture and serve a few other practical purposes. These tricks aren't a substitute for automotive chemicals and are best viewed as temporary or budget-friendly solutions.

Freshens Up Plastic and Leather Surfaces

A small amount of vegetable oil can temporarily restore some shine to plastic and leather surfaces inside the vehicle. Apply a little to a soft cloth and gently wipe the surface.

Some drivers also add a few drops of lemon juice or lemon essential oil to give the cabin a fresher scent. Just don't overdo it. Too much oil can leave behind a greasy film that attracts dust and makes surfaces slippery.

Helps Prevent Frozen Doors

During severe winter weather, moisture around doors and exposed metal components can freeze and make it difficult to open the vehicle. A very thin layer of oil can temporarily repel water and reduce the chance of ice forming.

However, oil isn't the best choice for rubber door seals. Automotive experts generally recommend a silicone-based lubricant designed for rubber, as it provides better protection without accelerating the material's deterioration.

Removes Sticker and Adhesive Residue

Removing factory decals, dealership stickers or other labels can leave behind stubborn adhesive residue on glass or painted surfaces. Vegetable oil can help soften the adhesive, making it easier to wipe away with a soft cloth.

Afterward, wash the area with car wash soap or another suitable cleaner to remove any oily residue and prevent a greasy film from remaining on the surface.

Temporarily Protects Leather Shoes From Moisture

One more unusual trick has less to do with the vehicle itself and more to do with the driver. Applying a very thin layer of oil to leather winter shoes can create a temporary water-resistant barrier.

That can help reduce the amount of melted snow, water and grime brought into the cabin on the soles of your shoes.

The trick should not be used on suede, nubuck or footwear made with waterproof-breathable membranes. For longer-lasting protection, a dedicated water-repellent treatment designed for the specific type of footwear is a better choice.
