Two Common Door Stains And How To Prevent Them

If you are serious about home maintenance, then it may drive you crazy to constantly find marks and spots on your garage door. While soap and water can usually help to clear away debris from your garage door, you can easily prevent most types of marks from showing up in the first place. Keep reading to learn about two types of common marks and how you can keep them from showing up.

Grease Stains

If you commonly see grease stains or black streaks on the exterior of your garage door, then these marks are likely coming from your torsion springs. The torsion springs attached to your garage door are large and tightly wound metal springs that sit near the top panel of your garage door. These springs are attached to brackets on each side of the garage door frame. A rod sits in between the springs and a cable is also attached to them. The rod keeps the springs in place while the cable helps to pull up the garage door.

Since the springs are typically made out of steel and are meant to move, they are covered with a lubricant to keep corrosion at bay. If the springs are covered too aggressively with grease, then the lubricant can get on your garage door. Use a ladder to reach the torsion springs and use a cotton towel to gently wipe the springs along the edge that is closest to your garage door to remove excess grease.

It is also possible the your torsion springs are starting to loosen or stretch out. This may mean that the springs are rubbing against the door and causing the grease to come off. If you see or feel that the springs are too close to the door, then this may be the problem. Other signs of torsion spring problems include a door that opens slowly and a door that jerks or slams when it begins to close. If you see these signs in addition to garage door grease stains, then think about contacting a repair specialist from a company like All Pro Quality Garage Doors, Inc. to replace the springs for you. The springs are under a great deal of pressure, especially when the door is in a closed position, and trying to attempt the replacement yourself can cause an injury.

Rust Marks

If you start to see rust marks forming on the bottom lip of your garage door, or if these stains start to appear on the upper part, then you likely have a problem with the rusting of the bottom lip on the door. This lip is a steel piece that is sometimes fitted with a rubber gasket so that the garage door does not slam into the pavement or concrete below it. While the lip is usually covered with a powder coating or enamel finish to protect it from the elements, like the garage door itself, the paint will chip off as the door meets the driveway. This is especially true if you have not invested in a spring adjustment in a few years and the torsion or extension springs are too loose.

The use of salt on your driveway can both cause and worsen the formation of rust and the spreading of stains on the garage door. Consider using a non-corrosive ice melting substance on your driveway like calcium magnesium acetate flakes. Use soap and water to remove rust marks as well. If you see multiple chips along the garage door lip, then think about replacing it with an all rubber seal. Remove the small screws or bolts from your old lip and snap or screw the new seal in place.

While it is best to find a seal or lip that is the same size as your old one, a slightly larger one should work fine. However, the lip may activate the garage door safety sensor that indicates that an object is obstructing the door. To stop your door from opening when the lip hits the ground, adjust the safety sensor so it is not as sensitive.
