What is the best way to clean oven racks?
A couple of different methods. Place them in a large heavy duty plasstic garbage bag being careful not to puncture the bag. Add in about a cup of ammonia, ite the bag off as tightly as possible and place on a flat area, preferably outside. The next morning you should be able to rinse of the racks with a hose and then wipe with a soap and water saturated cloth, rinse, rinse, rinse and place back in the oven.
Another method is to run some very hot water in the bathtub and add an enzyme time laundry detergent or dishwasher soap, place the racks in the mixture and let soak. Place some paper towels or an old cloth in the tub first so you don't scratch it. This is my least favorite way, because then you clean the racks with hot soapy cloth but then also have the tub to clean. :( You may have to use a bristle brush to remove caked, burnt on grime.
PUT THEM IN THE BATHTUB. COVER WITH HOT WATER AND ADD AMMONIA.
LET SIT A FEW HOURS. COME BACK WITH A COPPER SPONGE AND GO OVER THE TINES IN THE RACK TO REMOVE BURNT BITS. TURN OVER AND REPEAT. RINSE AND DRY. EASY AND SHINY CLEAN RESULTS.
I just research this myself, most manufacturers firmly state not leave racks in self cleaning oven During the cleaning cycle.
They need to be cleaned independently. It seems to be the best solution is to soak overnight in ammonia and these links below describe the process.
I recently used a plastic garbage bag and oven spray cleaner outside overnight. The racks look brand new!
Here are some helpful links that I hope will help —you choose the best solution for your need.
If you have access to a pressure washer, I just lay ours out on concrete and hit them with the washer. Flip them over and hit that side. Ten minutes time and they look like new. No mess no fuss.
