Here's how I clean the oven rack: I use 1 plastic bag and it's like new.

The required ingredients are as follows:

1 pellet
for dishwasher Warm water if necessary
3 to 4 tablespoons of chemical yeast

Necessary

Gloves
Rubber bowl
Bag
plastic Method
Pour warm water into a bowl and fill it more than halfway.
Add a dishhip pellet to the water and stir with a fork until completely dissolved.

Add some sodium bicarbonate to the bowl and mix again to combine the ingredients.
Pour the resulting solution into the bag with the grill in the oven. Make sure the bag is strong and will not break.

Tilt firmly with the bag and leave the grill to stand for at least 90 minutes. If the grill is very dirty, it is recommended to leave it in the solution overnight.
After the allotted time, open the bag in the sink and, with gloves, clean the grill with a sponge. The dirt should be easy to remove in this way.
Finally, rinse the grill with running water to remove any cleaning product residue.
By following these steps, you can clean the grill of your oven effectively and without too much effort.
