Oven Mate Just For Racks Cleaning Kit 5 "Amazing!!" Dr Ismer 03 February 2020 My oven rack has been dirty for years and no matter how hard I tried, I could not get it clean. The application of this product is super easy and I believe it is better to use the bags than the tray,that was the celaner has got less space to spread and more is on the rack. I left the thick gel on the tray as advised and when I took it out, it was soo clean. Like new. I did not have to scrub at all, just rinse with hot soapy water and then with hot water, which I did in the bath. Amazing! I will keep using it!!
