Sometimes you need a product that can tackle those really big jobs, so when an aerosol can isn’t enough, try the bulk Multi-Use Product. It’s the same Multi-Use product that comes in the blue and yellow can, but this size is ideal for soaking and dipping.Got some dirty, rusty tools that need some serious attention? Soak them overnight and let WD-40 remove stubborn grease and grime while penetrating the bonds between the rust and metal, and making the rust easier to remove later.Just like the regular aerosol, the bulk Multi-Use Product displaces moisture, protecting from rust and corrosion, and lubricating parts to keep equipment running smoothly.
