Simple Recipe for Homemade Penetrating Oil

What is penetrating oil spray?

Poke around in any mechanic’s garage for long enough and you’ll find a can of the stuff. Penetrating oil spray is an essential tool for rust removal. Applying the powerful loosening agent to rust can remove corrosion and loosen stuck metal components.

How to make your own penetrating oil spray?

Rust penetrant manufacturers are constantly working to improve their products. The latest formulations work better than previous brews. So if youre still using a 10-year-old can of penetrant, you might want to upgrade to the latest formulas from Liquid Wrench or the Specialist Rust Release Penetrant from WD-40.

Penetrating oil spray ingredients

As great as those new products are, occasionally you can get by with a home brewa 50/50 mixture of acetone and automatic transmission fluid. No chemistry is required to make this solution: just pour it into a spray bottle and you’re good to go. It has a strong smell and is far more flammable than commercial products, so when creating your own penetrating oil spray, make sure you use it outdoors and away from flames. It doesnt work as fast as commercial products, but if you need rust penetrant in a hurry, it will work.

Common uses for penetrating oil spray

Penetrating oil spray can be used in a variety of ways, including:

• Loosening stuck, rusted parts
• Reducing friction
• Removing sticky residue
• Preventative rust maintenance
