WD-40® is an all-purpose liquid for displacing moisture, corrosion control, lubrication, cleaning and penetration. It has the ability to penetrate the minute grain boundaries on all metals.
Protects metal from rust and corrosion, penetrates stuck or jammed parts, displaces moisture and lubricates just about anything. It is also great when it comes to cleaning grease, grime and other marks from most surfaces.
Supplied as a Flexible Straw Aerosol, it provides access to the most difficult spots that require a precise application. The flexible 18cm straw can be folded and maintain its shape whilst in use.
The Five Basic Functions:
CLEANS: gets under dirt, marks and grease, making it easy to wipe them away. It also dissolves adhesives, allowing the easy removal of labels, tape and stickers.
PROTECTS: metal surfaces with corrosion-resistant ingredients to shield against moisture and other corrosive elements.
LUBRICATES: lubricating ingredients are widely dispersed and hold firmly to all moving parts.
PENETRATES: loosens rust-to-metal bonds and frees stuck, frozen or rusted metal parts.
DISPLACES MOISTURE: Because WD-40® displaces moisture, it quickly dries out electrical systems to eliminate moisture-induced short circuits
