Well, after searching for myself on their website I found this.
Always rinse your jack plate off after every use, especially if used in salt water. Keeping the black polymer rods on the side of the jack plate free of debris is important for smooth operation. These rods are made of a high-tech material similar to what is currently used in hip replacements, meaning they are self-lubricated. It is important to NOT apply any grease or lubricant of any kind to these rods, doing so will cause buildup of dirt and debris causing the jack plate to stick or jump. If buildup does occur, we recommend using Dawn™ dish washing liquid, a soft brush and fresh water to gently clean the rods. Move the plate up and down several times to ensure soap is and water is getting to all parts of the rods and rinse completely when done.
