Ice and Garage Doors

#1
Here goes...... I work at an unmanned car wash (its automatic). My jobs is to do deposits, paperwork and of course clean and maintain it. Heres my question. Every winter i builds on the garage dor tracks and thus the doors cannot fully open or sometimes not at all. I have tried many things to combat this with no success. I have tried those sprays that you put on your windshield but due to the amount of washes it just gets washed away. I try lubericants but same thing happens. So every year i get tons of phone calls from the store that my C/W is attached to that the door is stuck. :teeth: Im hopeing one of you may know of something that may help weither it be a chemical or some way i can keep the tracks warm. Any and all help is greatly appreicated!!! :helpsmilie:
