As is known, iodine that comes into contact with the skin evaporates within a few hours.
The exact time depends on many factors, including air temperature, skin temperature, and other parameters.
It is for this reason, by the way, that the myth about the iodine grid as a way to detect iodine deficiency in the body is nothing more than fiction (let us recall that it is believed that if an iodine grid applied to the skin is quickly absorbed, then the person has a deficiency of this element).
However, there are situations when even such a short time is not available, so you have to resort to emergency measures to remove such stains.
For this purpose, you can use the most common laundry soap, hydrogen peroxide or soda solution.
An alcohol-containing solution is also effective. In extreme cases, you can use juice squeezed from a lemon.
Apply any of the listed products to the skin using a cotton pad.
Leave the "cleaner" on for a couple of minutes or simply rub the contaminated area of skin, then wash it off with clean water and soap.
The final touch is to apply a moisturizer.
