How to Touch Up a Scratched Window

There are several different ways that your windows can become scratched. Tree branches rubbing against windows is a common problem that homeowners face. Also, they can become scratched from pets and children; pets are a particularly common issue.  The first step is to assess the damage to the window. The panes of glass should be sealed with a vacuum between them. You need to check to see if the glass itself is scratched on the surface or actually cracked. If the glass is cracked, you’ll need to consult a professional. If you see condensation between the panes, you’ll also need a professional. However, if it’s just surface scratches and the seal is still good, you can likely fix it.

Lastly, you should run your fingernail over the window. If the scratch is deep enough that your fingernail gets caught in it, then it’s likely too deep to remove.


Cerium Oxide

 If you got a hardware store to get something to repair the cracks, you’ll likely find a product that contains cerium oxide. This compound is actually harder than glass; therefore, it can be used to polish glass. It works on the same principle as a fine grit sandpaper polishing wood.

Apply a small amount of the cerium oxide compound to the window and use a soft cloth to polish the scratches. If they’re shallow, they should buff out.


Use Glass Polish

 After you’ve buffed out the scratches as much as you can, you should use a window polish. You can use mineral spirits or toothpaste to accomplish this. Apply them to the window, focusing on the scratched areas. Polish them well with a soft cloth. This doesn’t actually remove the scratches but it does remove dirt and grime from the scratches, which will make them less visible.


Use Nail Polish

 You can also use clear nail polish to fill in the scratches. It might be slightly visible from up close, but it will generally make your windows look much better once you take a step back.

Finally, use a window cleaner to clean the cerium oxide and toothpaste off the windows. Once you’ve done all of that, it’s likely that the window will look significantly better. If the scratches still remain after you do that, you’ll likely need to have them professional repaired. Professional glass repair contractors use a clear compound to fill in the scratches. You could also choose just to have the window panes replaced. Though, that might not be an option if you have antique windows.
