Watch: How to Refill an Aerosol Can With Oil and Pressurize it

There’s not much I hate more than waste, especially when it’s something for which I’ve shelled out my hard-earned money. And my last couple cans of WD-40 have run out of pressure before running out of WD-40.

So I end up cutting the can open and using the WD-40 in a small plastic bottle and just brushing it on (or holding the can upside-down so it trickles out when I press the button), but that kinda sucks. I think I’m going to try this trick the next time that happens.

As for refilling an empty aerosol can, I’m not sure how practical it is but maybe if you buy WD-40 by the gallon or prefer to spray some sort of custom lube mix, it might be just what you’ve been looking for.

I would definitely be cautious about what kind of fluids I put into a can that’s been used before. Chemical reactions between the new and old liquids might end up making some bad stuff.

The best part is, you don’t have to drill holes or otherwise modify the can. Everything is done through the valve at the top of the can.

I like it.
