One of the best ways to extend the life of your crossbow is to properly maintain it. Two of the simplest ways to maintain your crossbow is to lubricate the flight rail and wax the string. Not only is it easy to do, it doesn’t cost much. Rail lubricant and string wax are very affordable yet incredibly effective when it comes to reducing wear and tear on your crossbow.
To lubricate the flight rail simply put a drop or two of rail lubricant on each side of the rail. Then take your finger and work the lubricant up and down the rail trying to cover as much as possible. If you can’t get it under the scope mount it’s not a problem. The string will carry the lubricant back as you shoot the crossbow.
Every manufacturer has different guidelines as to how often you should lubricate. A good general guideline would be every 50-60 shots. Just keep an eye on the rail. If it looks dull and dry, it’s a good idea to lubricate it. There should be a little bit of a sheen on the rail but lubricant should not be caked on. Just enough to make the top of the rail look glossy is the perfect amount.
Never use a vaseline type rail lube as it can gum up your trigger. I also do not recommend using RemOil or WD-40 to lubricate your crossbow rail. This type of lubricant has two big drawbacks. First, the ingredients are meant for metal and can break down your crossbow string, leading to catastrophic failure. Secondly, it has a strong scent that can hurt your chances in the woods. That smell may not matter when you’re using a long range weapon, but when you’re trying to get within arrow range of a whitetail it can make a big difference.
Waxing your string is also simple and easy. Just about any bowstring wax will work. Ex Wax and Ten Point wax are very popular choices. Just apply some wax to the exposed string on the crossbow and then take your thumb and index finger and work the wax into the string. I recommend waxing your string about every six months. If you hunt with your crossbow in the rain or other extreme elements, you may have to do it more often.
Do not put wax on the serving portion of the string. If you put it on the center serving it can create a gummed up trigger. Getting wax on the part of the serving that rides on the cam could potentially cause problems as well. Just work the wax into the exposed part of the string.
