How to clean inside the glass oven door

Sandra asked:

There are marks on the inside of my glass oven door (between the two).  How can I get them clean without dis-mantling the whole door?

Judy suggested that:

1. If this is a relatively new oven, contact the manufacturer because I think this may be a problem with the seals around the two layers of glass.
2. If this is an older oven, then maybe phone call to a small appliance repairer would be useful before you try to dismantle the oven door.

Cam writes about his recent experience and gives instructions for dismantling the oven door.

“I recently had the same problem – turned out one of the seals had been turned in when the door had been put back together last time.  Often these rubber seals can degrade.  I was able to reseat the seal once I had cleaned the interior.

Unfortunately, the only solution I could find was to dismantle the door.
Most doors can be removed from the over by simply opening them and lifting the hinges up so they can be slid out of the oven chassis.  This may be a 2 person job due to the with of some doors.

Lay to door on the kitchen floor on an old sheet.  The outer can usually be removed from the door frame by unscrewing screws somewhere around the perimeter of the door.  Simply slide the outer off the inner to gain access to the inside of the door.  Make note of the way the door is put together.  Check all seals and clean the interior and make sure you repeat in reverse the disassembly instructions.  Refit the door by sliding the hinges back into the chassis.”
