The use of any chemistry in everyday life is not desirable, especially when it comes to kitchen and dishes. You never know, you will not wash everything afterwards, it will remain somewhere, and this will not lead to anything good. At least you will stand in line with the "white friend" and urge each other on, shouting "faster ..."!
Therefore, my wife, finding a frying pan, which is more than a dozen years old, asked me to find a way to clean it from soot, without using any chemicals. And I found this method, and easily brought it to life.
Of course, this method is not at all safe, and you need not a small room to bring it to life. It is based on heating a pans with carbon deposits with a gas burner, and sharply cooling them in ice water.
You see in what a deplorable state the frying pan. It is covered with soot, and it is very old, in some places, the top layer of soot begins to peel off. Now I will clean it.
I put a wooden square bar 200 by 200 on the table, put the frying pan on it, bottom up.
I connect the gas burner and start heating the pan with the flame. You need to warm up the pan very well, here the basis of the "wedge by wedge" method, that is, in fact, I have to burn carbon deposits, using very high temperature, or soften it as much as possible, and then use the temperature difference during cooling, without making any special efforts clean up.
After a good heating of the frying pan, I take a bucket of cold water, and I put it very hot in the bucket. Since the frying pan is very hot, and so is the handle, I use special gloves to do this.
The moment you lower a hot frying pan into a bucket of cold water, do not stick your nose in there, there is a high probability of burning it. Perform this procedure with outstretched arms.
After there has been a sharp drop in the temperature of the frying pan, we take a metal sponge and begin to clean the carbon deposits that have already exfoliated from the frying pan itself.
In the beginning, it turns out something like the one shown in the photo below:
Continue to work with a metal sponge, and after fifteen minutes, your old frying pan, which was covered in old soot, will return to its original form. Of course, the appearance will not be entirely original, its surface will have small scratches on the outside, from a metal sponge, but still, the difference is huge. In the photo below, I think you can see it perfectly:
Just like that, without the use of chemicals, I brought the pan with carbon deposits to a fairly normal state. The wife is happy! And this is a very great joy in life when you do something pleasant to someone, especially to your beloved wife!
