It’s not new. The blue and yellow can is about as familiar as anything I remember from my childhood. Banished to a shelf in the garage, I assumed WD-40 was an automotive thing. Boy, was I wrong! This stuff is amazing. And cheap. Not long ago, I bought an 8-ounce can for $1.71 at Home Depot.
My recommendation is to apply WD-40, let the product do its work then remove it. Some say that a build-up of WD-40 can cause its own sticky mess over time. So here’s the deal: Use it then remove it.
WD-40 is a petroleum-based product (so is Vaseline). WD-40 comes in a tiny 3-oz aerosol can, larger 16-oz. or by the gallon, which you can pour into your own spray bottle. While the aerosol propellant is flammable, the product itself is harmless to humans, according to the manufacturer.
WD-40 gets things unstuck and a lot more. I know. I go through it like it’s water. But don’t worry. It’s cheap. I once bought an 8-ounce can for $1.71 at Home Depot.
