WD-40 gets under dirt, marks & grease making it easy to wipe away. It also dissolves adhesives, allowing easy removal of labels, tape, & stickers. WD-40 protects metal surfaces with corrosion-resistant ingredients to shield against moisture & other corrosive elements. WD-40's lubricating ingredients are widely dispersed & hold firmly to all moving parts. WD-40 loosens rust-to-metal bonds & frees stuck, frozen or rusted metal parts
