WD-40 vs Silicone
WD-40 has 2000+ uses.
From gum and crayon removal to preventing rust and loosening old, stuck and
already-rusty parts but, for new door rollers a silicone spray lubricant is a
WD-40 contains solvents that will dissolve and remove the grease
that has been applied to door rollers at the factory. The purpose of this
grease is to provide a durable lubricant for the ball bearings in the roller.
Therefore, it is recommended that WD-40 should not be used on new rollers, but
rather use a silicone
if lubrication is required. For older rollers that
already show signs of corrosion, try the WD-40. But first, clean the roller tracks with a vacuum.
If it still doesn't roll well you will likely need to remove the door
and replace the rollers.
