What type of lubricant is used for runner guides?

Runner guides require a lubricant that minimizes friction while avoiding build-up that could attract dirt and debris during use. A dry Teflon spray or 100 percent silicone lubricant is particularly effective for this purpose because it provides a slippery surface without creating a sticky residue, which helps maintain optimal performance of the runner guides over time.

Using a lubricant like dry Teflon or silicone ensures that the lubrication remains effective under various conditions, as it does not attract dust and dirt that can compromise the functionality of the runner guides. This type of lubricant is also resistant to water and can adhere well to surfaces without running off or breaking down.

Other options, such as vegetable oil or petroleum jelly, could leave a greasy residue that collects dirt and can lead to unwanted friction and wear. Heavy machine grease, although it provides a very slick surface, is too thick and can impair the smooth operation of runner guides by causing drag. Therefore, the use of a dry Teflon spray or silicone lubricant is the most appropriate choice for ensuring optimal performance and longevity of runner guides.
