Thank you for sharing your concerns, LoriK49329. Food, grease, drips and streaks can get in between the glass panes in a variety of ways. Sometimes it drips down through vents in the top of the door. Grease from the oven can travel through steam vapors into the door where they settle leaving spots and streaks. Removing anything from in between the glass pieces will be a challenge. Try the following steps: By inserting a towel on a long-handled stick, you can gently clean between the glass panes without disassembling the door. First, find the vents on the door if you have them. STEP 1:It may be easier to remove the door from the hinges and lay it flat on the floor. Many oven doors simply lift right off of the hinges; others will require loosening a few screws first. STEP 2: Secure a towel or soft cloth (long socks work well) to the handle with duct tape or other strong tape. Make sure it’s well fastened so it doesn’t come off and become stuck in the door. Moisten the towel or soft cloth with the window cleaner or other cleaning product and insert it through the vents. STEP 3: Repeat with a clean cloth until all of the debris is gone and replace the door on the oven and enjoy the clear, clean view. I hope this helps!
