Day-to-day accidents can cause scratches on your patio doors--whether it's pets, kids and even accidentally hitting the door with your foot. But there's a simple way to remove these scratches.

Step 1

Use a product such as Scratch-B-Gone, which was designed to remove scratches from surfaces--including glass and stainless steel. These products fill in the scratches on the door and then buffs and polishes the surface to hide the problem. However, it doesn't work in all situations, so you'll need other options. If you find that the product doesn't work, apply warm, soapy water to the spots and wipe it off before continuing.

Step 2

Apply a thin coat of jewelry polish to a dry cloth and rub it in small circles on the scratches. If you have any Scratch-B-Gone left on the door, the polish might not adhere properly. This helps fill in the scratches slightly and also highlights the troubled spot. It also works with the sandpaper and helps you buff away the scratches.

Step 3

Rub the scratches with a piece of fine-grade sandpaper, using a circular motion. This works to slowly buff out the scratches and make the door look better. Take your time, but if you're in a hurry, try an electric sander with the buffer attachment.

Step 4

Make a mixture made up of 4 parts water to 1 part ammonia and pour it in a spray bottle, making sure to protect your face and mouth with a mask and goggles. Ammonia can cause serious respiratory problems when inhaled and burn your skin if you accidentally touch it. Also take care not to mix it with any other household ingredients including bleach or other cleaners.

Step 5

Apply the ammonia and water solution directly to the scratches and then immediately wipe away the solution with a clean paper towel. This removes the dust and grit from the sandpaper to reveal the door underneath. If the scratches are still there, try running through the steps again.
