Hello all! Our garage door is becoming louder when it opens/closes on the frequently used side. I've done enough poking around to know:
1. Do not use WD40 on it.
2. Tracks probably need cleaning... somehow.
3. No one can agree what lubricant to use, and whether you should lubricate the tracks or just the hardware on the door itself.
Help please? The volume of contradictory information is overwhelming on this.
