You can use vegetable oil in an emergency—but it’s not recommended.
While it may quiet a squeaky hinge briefly, vegetable oil causes problems over time and is a poor substitute for proper lubricants.

Why Vegetable Oil Is a Bad Idea

1. It Turns Sticky

Vegetable oil oxidizes and thickens as it ages. This creates a sticky residue that:

• Attracts dust and dirt

• Increases friction over time

• Makes squeaks come back worse

2. It Can Go Rancid

Being organic, vegetable oil can:

• Develop unpleasant odors

• Break down and gum up the hinge

3. Poor Long-Term Lubrication

It lacks the additives needed to:

• Reduce metal-on-metal wear

• Protect against corrosion

• Stay in place under repeated movement

When It Might Be Acceptable (Very Short-Term)

Use vegetable oil only if:

• You need a temporary fix

• No proper lubricant is available

• You plan to clean and re-lubricate soon

If you do use it, apply one tiny drop, then wipe off all excess.

Better Alternatives (Much Better)

Best Choices

• Silicone spray – Clean, non-greasy, long-lasting

• White lithium grease – Excellent for metal hinges

• PTFE (Teflon) spray – Low friction, dust-resistant

Acceptable Household Options

• Mineral oil (non-food)

• Paraffin wax (rub on hinge pin)

• Petroleum jelly (small amount)

Avoid cooking oils whenever possible.
