A silicone spray that was good is advised hinges, and when lubricating the garage door components such as the most effective portion of the chain railing, shanks, metal rollers which have the lock, the arm bar, as well as ball bearings. There are parts that will not be sprayed with any lubricant such as the underside portion of the spring, the chain, the garage door track, as well as the chain rail while there are elements of the garage door that need lubrication.
