    Potions to remove oil and rust?

    The easiest way to remove oil is to get some cheap laundry detergent and soak it in water; If you want to remove rust, get some concentrated sulfuric acid back, dilute it yourself, and soak it.

    The two can be mixed together and degreased and rusted at the same time, but they should be properly heated. It is recommended that the concentration of sulfuric acid is less than 15%, and the treatment time is controlled according to the rust and oil stains, generally no more than 15 minutes, and the temperature is about 50 degrees.

    The more complicated thing is to buy a special degreasing and rust remover, and after buying it, you can get it according to the construction conditions given by the manufacturer.
