In a world that seems uncertain and strange at times, we are all very lucky to have the certainty of a product like WD-40.

Although it is always reliable when used for its primary purpose, people have discovered all kinds of unique ways in which WD-40 can help with simple tasks.

For instance, did you know that WD-40 can be used as a fire starter?

All you need to do is spray the magical substance on some cotton balls and then take them with you into the great outdoors.

Not only will it spark up a flame, but the flame will remain lit for over 10 minutes or so. For campers, this can be a truly transformational tool.

Another idea involves using WD-40 as a preservative for your sidewalk chalk artwork. Simply spray some of it around the edges of your design, and you will notice that it stays much longer than usual.

For business owners who use the sidewalk for advertising, this can be a great tip.

And for those of us who always seem to end up with our dinner on our sweaters, WD-40 is also a great stain remover. Simply spray the stain, and then use good old soap and water to wash it away.

With so many innovative ways to use this sensational substance, you might want to stock up so that you always have one around the house.
