If the stains that “decorate” the oven glass have been there for a long time and don’t want to be washed off, a simple trick will help.
To do this, you will need to preheat the oven to a temperature of 50 degrees.
When the goal is reached, turn off the appliance and open the door for a minute.
Your task is to wait until the door stops being hot and becomes warm.
After this, apply a small amount of cleaning agent to the glass - the most budget option will do - and close the oven door again.
After 5 minutes, you can begin cleaning using a special scraper designed for cleaning glass-ceramic surfaces.
If you don't have the right tool at hand, replace it with a hard sponge, then wash off the remaining cleaning agent and dirt with a cloth soaked in clean water.
This simple trick will make the most stubborn stains much more pliable, making them easy to remove.
