There are three things that I use WD-40 for most: loosening rusty screws, de-squeaking hinges, and helping unlock frozen car doors. But there are lots more uses — the company lists 2,000 (!) like cleaning crayon from “just about anywhere” or freeing stuck LEGO blocks. Well, now WD-40 is looking for a whole new approach, and they’re willing to pay you for it. They’ve joined Edison Nation in a search for a new WD-40 product or innovation to the original brand. If you come up with a great new product idea or use, you’ll win $2500 and a percentage of product sales for up to 20 years. The product search ends May 20. Learn more right here. –Mary T.
