The best and easiest way is to use a Hurricane Turbo scrubber. WE found ours takes all the hard work out of cleaning. We got ours online, but you can buy them at Walmart now and maybe other retailers. It is an investment for $40, but well worth it and it is great for ovens, range tops, car tires, tiles, and more. We love ours and use our regular non toxic cleaner and it works great. Hope this helps!
