How to clean secondary glazing

Please follow the steps below for help with cleaning your secondary glazing.

  • Remove the 'Anti Crabbing' guide blocks on the sides of the insert.
  • The unit can then be pushed to one side and lifted out.
  • If the secondary window slides horizontally instead of vertically you will need to position the sliding section into the middle of the frame and then lift before trying to pull the bottom out. This should release it from the frame and enable cleaning.
