How to clean your oven trays

The principle for cleaning oven trays and racks is simple: Let time and soap do the work.
Of course, this takes less time and is easier the more often you do it.
If it is really stuck on, you may need to add more soap, water, and time, but eventually the soap dissolves the dirt, making it easy to remove.

Can't you use something stronger to make it go faster? -Yes, certainly. There are almost always stronger and more powerful chemicals available, but the question is whether you want to “spend time with them” and whether you want to cook on that surface later.

This is my suggestion for cleaning oven trays and racks without much effort and entirely without unnecessary chemicals.

1. Soap the trays
2. Work up some foam with a sponge or eco-fiber cloth
3. Place them in a plastic bag and leave them overnight, or even for several days if they are very dirty. If you leave the trays longer than overnight, it is a good idea to check them to make sure they are still wet with soap and water. They must not dry out.
4. When you notice that the dirt is coming off, simply scrub them with an eco-fiber cloth, sponge, or stiffer brush—whatever suits you. Personally, I find a copper scrubber very effective for oven racks. It is so easy to run it around each “bar” of the rack and get it clean in a single stroke.
5. Then all you have to do is rinse and dry them!

1. What is the easiest way to clean oven trays?
Answer: Soap the baking tray with soap and water, and leave it in a sealed plastic bag until the soap has dissolved the dirt and you can easily rub it off. 
More time and soap make the job easier.

2. Are there stronger chemicals that get the job done faster?
Answer: Yes, there is almost always a stronger chemical, but the question is whether you want it in your kitchen.

3. Does this method work on grill grates as well?
Answer: Yes
