Glass scratch repair process

Filed under Removing scratches from glass

If you haven’t done so already, do the fingernail test and choose your polishing compound, as described here.

Removing scratches from glass involves the use of a polishing compound and, for lighter scratches, some elbow grease. For a more visible scratch you may need a buffing machine, or an electric drill, with a polishing attachment.

Before you start, here are some points of caution:

  • Be careful not to overdo the polishing, as this may leave an indentation in the glass that will distort the light and weaken the structure of the glass.
  • If you are using a hammer drill, ensure the hammer setting is switched off!

 

Manual method

Use this method for removing lighter scratches from glass.

  • Clean the glass thoroughly
  • Smear a generous amount of polishing compound onto the scratch
  • Use a soft, clean cloth to polish in a circular motion over the affected area. This may take a while, so be prepared for some elbow grease!
  • Clean and dry the glass with a lint-free cloth. Is the scratch still visible? If it is, repeat the process.

 

Mechanical method

Use this method for medium scratches.

  • Clean the glass thoroughly
  • Smear a generous amount of polishing compound onto the scratch
  • Wear safety goggles and use either a buffing machine or an electric drill with a polishing attachment
  • Clean and dry the glass with a lint-free cloth. Is the scratch still visible? If it is, repeat the process. With medium scratches, you may have to accept a reduction in visibility, as you may not be able to completely remove the scratch.

Hopefully your glass should now be scratch-free, or the scratch at least considerably less visible.
