The main purpose of crossbow waxes and lubes is to keep the strings and cables of your crossbow in good working condition and prevent them from wearing too early. There is some maintenance you must not neglect doing, otherwise you may end with a failed hunting trip or worse, an injury. Neglecting to properly maintain your crossbow may also potentially cause serious damage to your crossbow over time.
While it is important that you wax the string and cables thoroughly, it is equally as important to avoid the
servering of the string. Keep in mind that if you are using hard or low-quality
crossbow waxes, this will soon cause wax to build up in the trigger box, subsequently making the crossbow almost impossible to cock. In the event this actually happens, the only solution is to take the trigger assembly apart and give it a thorough cleaning. This is not an easy as it sounds and not a do-it-yourself project for most. You might need to return the crossbow to the manufacturer to fix the problem.
In addition, it is recommended that you use a light-weight, oil based
crossbow wax over the Vaseline based waxes. Make sure to re-lubricate the
crossbow rails every 20 shots and strings every 50 shots or so. Lastly, the scent of string is very strong, which will catch the attention of your prey and startle them causing them to run away. This is highly frowned upon by veteran hunters, so be sure to stay downwind of prey.
