Dealing with a rusty garage door? You’re not alone. Garage doors are frequently exposed to outside elements that can cause rust build-up over time. This is especially true of cheaper metal doors or for those who live closer to the ocean.
Minor rust can be buffered out with sandpaper or removed with a solvent. If it’s a large amount of rust, you’ll probably need to repaint the whole panel after removing the rust.
For rust on garage door parts, use a solvent made for rust and gently scrub. Afterwards, apply a light amount of white lithium grease or silicone spray to prevent further corrosion.
For panels with heavy rust damage, you may need to purchase a new garage door. Some parts like garage door springs or hinges may require replacing as well if the rust damage is significant.
