Cleaned my oven like a champ! Image shows before and after. Before is from like 5 years ago, and I’ve cleaned it since then but need to clean it again. You can still see the difference in the door window. Follow the directions, no streaks, foaming was great, easy to spray and did not arrive broken like some cleaning products do from Amazon. It worked soooo well it’s the only thing I use to clean my oven, because it’s the only thing I need. The smell is rough, and very strong, but that’s to be expected with a cleaning chemical. I inherited this oven from my great grandmother and she bought it back in 2005. She kept it up but never deep cleaned it - one cleaning and it was brand new. Read more

I was having trouble getting the glass door on my Ninja 9-in-1 air fryer clean. One spray of this and letting it set 10 to 15 minutes, the grime just wiped away with a paper towel. Super easy! Read more

Works great. My oven was really bad and it worked right away. I did have to go over it again, not sure i sprayed evening the first time but the bottom of my oven needed a second time as it was really bad. You will definitely need to use gloves and a mask. Read more

It's a very good degreaser. Although its smell is very strong, it's recommended to wear gloves and a face mask. But it removes grease incredibly well. Read more

Zep Heavy Duty is extremely effective and dissolves grease almost instantly. It works great not only on ovens but also cleans pans very well, cutting through tough buildup with little effort. It’s definitely worth the price, and I’ll be buying it again. Just make sure to wear gloves and a mask, as the smell is very strong—but the results are worth it. Read more

I'm embarrassed to say how many years since I cleaned my oven but it just proves how good Zep is. I bought 3 cans because my oven and racks were in horrible condition. I also bought oven bags to put my oven racks in after spraying them with Zep. After letting them soak for a day with the Zep on them I rinsed the racks and I could not believe how clean they are. Nice and shiny. There were a few places that needed a little scraping but that's minor. Read more

Saw this on a Youtube video for cleaning an oven. Used it on an electric oven that was in need of cleaning and it worked well. I decided to leave it on longer than they recommended to be sure it worked, left on for about 1 hr. This is a double oven and when I read that it said to heat the over before spraying I was a little surprised but tried it on one of them. I really did not like this direction because when I sprayed this stuff and it hit the heating coils it put off a lot of steam and it was chemical smelling. This was not good and something I didn't like so I did not do this for the second oven. With the heat in one over and none in the other, I didn't notice any difference in how it worked for me. Both came clean and look good. So for me I would not preheat the oven again and endure that smell again. Read more
