Have you noticed a scratch in one of your home’s window panes? If so, here are a few options.
First, drag your fingernail across the scratch. If your nail doesn’t sink into it, the damage is probably shallow enough to repair. If your nail “catches” on the scratch, the damage will be more difficult to cover up.
To repair the scratch, clean the window thoroughly, then use a lint-free cloth to dry the glass. Squeeze a little bit of toothpaste onto the glass and use your finger to rub it into the scratch. Then, wipe off the excess. After the toothpaste has dried, buff the glass.
If you’d prefer, you can use jeweler’s rouge (iron oxide) or Ceria (cerium oxide) instead of the toothpaste. Both are mild abrasives. Apply either product to the scratch in the glass. Once it has dried, use an electric buffer with a lamb’s wool pad to buff the scratch.
