Why You Need WD-40

A few weeks ago my son could not get his truck door to unlock. It is an older model and has no remote, so we had to use the key. We were experiencing bitterly cold temperatures and already there was over two feet of snow on the ground, so I speculated some moisture had penetrated and frozen the lock. Out from the garage came WD-40 and with a couple of squirts to the lock the problem was solved.

Invented in the 1950’s to protect missiles from corrosion, it soon became available to the public and is now sold in over 160 countries. As the brief following list shows, if you don’t already have a can or two around the house you are missing out on an amazing product.

It lubricates practically anything. Think squeaky hinges, stuck zippers, stubborn windows and sticky drawers.

Removes grease and stains, such as road tar, crayon marks, tape residue, lipstick, barbecue grill grime, bug goo, stove grease, you get the idea.

It protects metal from rust and loosens items that are already rusty. Works great to loosen lug nuts and rusty bolts and as a rust preventative for your tools.

Strange uses: I read (on the internet, so it must be true) that it can relieve arthritis pain by spraying it on painful joints, and help catch fish with a little squirt to your lure. If I had to make up other uses for WD-40 at the top of my list would be “relieves constipation.”

This is not intended to be an all inclusive list, but rather a general reminder that just this one product can serve as a frugal, all in one alternative to multiple household cleaners and protectants.

For a monster list of uses, just go to the source.
