I used to be one of those people that would buy that easy off oven cleaner and let the chemicals do their job. I would scrub for hours after breathing in those nasty fumes and the job would eventually be complete. Now I have found a way to get your oven looking brand new again and there are no chemicals involved.
Using nothing more than a drill, wire wheel, and some soapy water, you can get your oven looking brand new again.
First turn the oven on to high for about 10 mins to warm it up inside. Turn the oven off and spray it down with a dish soap and warm water concoction.
After letting it sit for 10 minutes begin using the drill with your wire wheel attached. Take it slow as this will begin to spit grime and gunk everywhere. Wipe away sections as you scrub them to see where else you need to clean. I used a bucket of soapy water beside me to wipe and wash frequently while cleaning.
You can also use this setup for your oven racks and they come out just beautiful! I used the bath tub to scrub my racks and they look brand new again.
This has got to be the cleanest I have ever seen an oven unless it was just purchased and it took less than an hour to complete. You can get a whole set of wire wheels here off Amazon to get your appliances looking brand new again!
