Kroil

Free stuck and seized parts

Salt and corrosion seize fasteners and parts on a boat like nothing else, and Kroil is the legendary penetrating oil that frees them. Kroil is known for creeping into the tiniest spaces, working into rusted threads, corroded fittings, and seized parts to break the bond of corrosion so you can free a stuck bolt, nut, or component that ordinary penetrants and brute force cannot budge. For boaters fighting the rusted, seized hardware that the marine environment creates, Kroil is the product to reach for when something is locked tight. Keeping it on the shelf can save a fastener, a part, and a lot of frustration when corrosion has done its worst.

Using Kroil well means giving it time to work. Apply it generously to the rusted or seized threads and joint, and let it penetrate, reapplying and allowing dwell time for badly corroded parts, since the penetrant needs time to creep in and break the corrosion bond. Then work the fastener or part free, repeating as needed. Patience and reapplication get the toughest jobs. Always use it with proper ventilation and care, since it is a solvent. Review the product directions before use. With Kroil on hand, you free the stuck, rusted, and seized parts that the marine environment locks tight.
