To anyone unfamiliar with this stuff, it's like gloopy wax that when you put it on metal with a brush or thin and spray it, eventually it goes hard like candle wax and seals the metal preventing corrosion. The 5L tins are cheaper per volume than smaller sizes and its useful for protecting metal things if you live in a rust inducing environment like damp UK and/or near the sea. There are similar products around that work on grease/oil coating. Steam cleaning will remove waxoyl should you ever want it gone.
