WD-40 is a penetrant spray made of a blend of lubricants that is great for anti-corrosion, water displacement, and soil removal. WD-40’s five essential functions are to lubricate moving parts, penetrate through rust and grime, protect against corrosion, remove dirt, grime, grease, and displace moisture. WD-40 was invented in 1953 by a young company called Rocket Chemical Company, which embarked on a mission to create rust-prevention and degreasing products for the aerospace industry. In 1958, the company started selling the product in stores, and since then, it has become a household necessity. Buildworld sells a range of WD-40 products, which comes with a Smart Straw applicator for precision application. It is a multi-use product that can stop hinges from squeaking, loosen rusty or stuck parts, remove rust and grime, and much more.
