Blaster Garage Door Lubricant is a premium silicone-based lubricant that eliminates squeaky garage doors and prevents rust and corrosion. Blaster's Garage Door Lube leaves a tack-free film and won't accumulate dust and dirt. It helps reduce friction and wear and in some instances, its extreme pressure agents make it a suitable replacement for grease. It effectively helps stop squeaks associated with garage doors and mechanisms. Garage door mechanisms include rollers, hinges, springs and door tracks. This silicone-based lubricant is also great for cables, chains, bushings, bearings and window tracks. Simply spray directly on garage door mechanisms and apply regularly to ensure proper protection. Make sure to consult your garage door opener manual before using this lubricant on opener drives.
