It's time to clean my oven

Hope this helps:

Which is the best oven cleaner you can buy? Well, look for one that does not require an overnight soak. The oven cleaners that are available today are much less toxic than they were years ago. The newer cleaners also will not run and create a bigger mess like the ones that we used a few years ago. Now the cleaners will stay in the places you sprayed them and thoroughly soak into the grime and built up grease. You should wipe off as much of the dried loose food before you apply the cleaner. Let it set for the amount of time that is on the instructions. The product should soften dried on food so that it will easily wipe off when the cleaner has thoroughly soaked in. If you find that some of the burned on food will not clean up you should check with the instructions from your stove’s manufacturer for what type of abrasive you can use on the oven. You might find that you have left the oven cleaner soaking for too long and it has now dried up. You can fix this problem by laying a damp rag over the cleaner and it should soften up the cleaner.

Take care !!
