The WD-40 Heavy Duty pail contains 55 gal. of non-aerosol multi-use lubricant that can be applied to almost any item to reduce friction and protect metal from rust and other corrosion. With over 2,000 documented uses, WD-40 is also commonly used to loosen stuck metal parts, remove grease and grime, silence squeaky components, and displace water to remove moisture from electrical systems. Even after the lubricant has dried, it continues to protect surfaces from corrosion. The lubricant’s petroleum base permits use on most materials, excluding polycarbonate and clear polystyrene. It has a non-aerosol formula that also dissolves adhesives to remove stickers and labels, and allows the pail to be recycled more easily than aerosol cans. The pail contains 5 gal. of lubricant for heavy duty use in industrial applications.
