Take a clean, damp cloth and dip it into some warm, soapy water. Gently rub it in a circular motion all around the scratch. This will remove any dirt and grease, making it easier to get rid of the scratch. Dry the area with a clean, dry cloth when you’re done. Shallow scratches can often be buffed out. Run your fingernail across the scratch. If it “catches” in the groove, then it is too deep to be buffed out. Deep scratches can only be removed by other methods. A mild abrasive, like toothpaste, helps wipe the scratch away. Use a paste variety, not a gel one. You won’t need to put much on the cloth. Just use enough that you can smear it all over the scratch. Instead of toothpaste, you could also try:  Furniture polish. Commercial plastic polish. Baking soda. Take a couple spoonfuls and mix in enough drops of water to form a smooth paste. Go over the whole scratch, from one end to the other. This buffing action is what can rub the scratch out of the plastic. Keep buffing until the scratch disappears. When you’re done, wipe the area with a fresh damp cloth to remove the paste and residue. Then, take a clean cloth and wipe everything down to dry it.
