In 1894 George Cole named this product because of its triple ability to “clean, lubricate and protect.” Over a hundred years later, 3-in-1 oil is to the shop what ketchup is to the refrigerator — it’s not complete until you have some.
The formula consists of pale spindle oil with a small amount of corrosion inhibitor and citronella oil which gives the product its familiar smel; my father’s workshop always smells of it. We use it around our shop to oil knife hinges, bicycle chains, and countless other metal moving parts.
You can find 3-in-1 oil at any self-respecting big box or hardware store. And, a $2 squeezable can will last most folks for years. Trust us: your tools will thank you for it.
