WD-40 Multi-Use Product Spray with Smart Straw
Even after all these years, WD-40 is still one of the top spray lubricants available on the market. Their proprietary formula works extremely well for a wide range of purposes, including lubricating, loosening rusted parts, freeing sticky mechanisms and driving moisture out of mechanisms. It’s excellent for use on rusted parts as it will keep moisture out and lubricate the metal, allowing rust flakes to be ground off. This particular package comes with their "smart straw" which keeps the straw permanently attached to the can, so you can't lose it. Flip the straw up for pinpoint accuracy or flip it down for area spray. This is the one spray lubricant that I use regularly.
