Windows bear the brunt of the elements on a daily basis. A glass window that has got scratched from a flying piece of debris can be cleaned using toothpaste. The abrasive nature of the toothpaste will remove the scratch by evening it out with surrounding area. The procedure is straightforward and can be done by a person of any age, although young people must be discouraged from rubbing the glass too hard as that could lead to it cracking or even breaking.
Spray the side of the window where the scratch is located with glass cleaner. Wipe the side of the window with a piece of newspaper. Let the window dry.
Apply a line of toothpaste along the length of the scratch. Place a clean edge of the lint-free cloth an inch or so to the left of the scratch.
Press down on the glass gently as you wipe across the scratch with the clean edge of the lint-free cloth. Remove the lint-free cloth when you are an inch or so past the end of the scratch.
Repeat this procedure with additional toothpaste and clean edges of the lint-free cloth until you can no longer see the scratch.
Dispose of the lint-free cloth in the trash.
Do not use flavoured toothpaste as the flavouring crystals can further scratch the glass.
