Having scratches on your home's windows can be very frustrating. Not only can they obstruct your view and become an eye sore, but dirt and dust collects in the scratches, which just makes it worse. Before you have your windows replaced, try repairing the scratches. As long as they aren't too big or too deep, you should still be able to remove them.
Decide if the Scratch Can be Repaired
Before you start removing the scratch, you need to assess it and see if it is too deep to repair. A scratch should only be on the top surface of the glass film, not going through the glass itself. You can test it by using your fingernail. Place your fingernail into the scratch and see how far down it goes. If some of your fingernail disappears into the scratch, it is actually a crack, and might require replacing the window. In this case, consult a window professional to figure out if a repair is possible. If you fingernail rested on top of the scratch, it should be shallow enough to remove.
Clean the Window
If you have decided to try removing the scratch because it wasn't too deep, you need to start by cleaning the window thoroughly. Use glass cleaner with a lint-free cloth. Microfiber is perfect for windows because you won't leave lint behind. The purpose here is to get the window clean. Don't worry too much about streaks. You can clean the window again when you're done removing the scratches. After the window has been cleaned, use a grease pencil to make a circle around the area of the scratch to mark it.
Prepare the Polishing Powder Mix
The best way to remove a scratch is by using a polishing powder. You can either purchase it separately or get a glass scratch repair kit. These are available at most hardware stores. Follow the directions on the package to mix the polishing powder with water. Use a disposable bowl as you most likely will just want to throw it away when you're done. The bowl should have a flat bottom, which the larger disposable storage containers have.
Use the Polishing Pad
When the polishing powder has been mixed, grab your polishing pad that came in the glass repair kit and remove the backing. This is placed on a rubber backing pad that fits on an electric drill. Attach this to your drill and make sure it is tightened. Use a rag to apply some of the polishing powder mixture onto the scratched area, covering the inside of the marking you made with the grease pencil. Next, get your drill and place the polishing pad inside the marked area on the window and turn it on to a low speed. Move it around the area in a circular motion for several seconds.
Repeat the process by adding more polishing powder, then using the drill and polishing pad once more. Continue doing this until you start to see the scratches disappear. Clean the window once you're done. To learn more, contact the experts at Fary W. T. Bros Lumber Co.
