STAINS ON THE SKIN
Hand epidermis stains can be removed mechanically, e.g.. with pumice stone or sand. In the case of stains on the hands, this procedure is not difficult, however, it is more difficult to remove stains from the face, where the skin is less resistant, more sensitive than on the hands and reacts more strongly with irritation to any mechanical stimuli.
Some stains can be removed from the face with chemicals, which causes less skin irritation. From stains, that can be chemically removed from human skin, nicotine stains should be replaced, appearing often on the fingers of smokers, as well as iodine stains. Using chemicals to remove these stains, may cause some skin irritation, therefore, after the treatment with chemicals, it is necessary to wash your hands with soap and water. After drying the washed hands, rub them with a greasy cream.-
Ink. These spots usually disappear after wiping the skin several times with lemon juice or a solution of citric acid. If this treatment proves to be insufficient, the stain is saturated with a solution of potassium acid oxalate or oxalic acid. These chemicals can only be used then, if the skin is perfectly healthy. You can also remove ink stains with bleach.
Tar dyes -> colors.
Colors (e.g.. tar dye stains, lipsticks for lips, etc.). The stained place is wiped several times with a cotton pad saturated with a fatty cream. This treatment should be repeated, if there is a need for it. Many dyes can be dissolved by rubbing the stained area with alcohol or acetone.
Oil paints and varnishes. These stains can be easily removed from the skin with a solvent, e.g.. turpentine, gasoline or stain remover. Nitro paint stains are treated with a nitro solvent, acetone paint stains - amyl acetate.
Berries. The areas of the skin stained with blueberries are wiped several times with a solution of tartaric or citric acid. The teeth can be cleaned of berry stains in the same way or using lemon.
Vegetables -> fruit.
Iodine – Iodine-stained skin is wiped with a solution of ammonia or sodium thiosulphite, then it is washed off with soap. You can also treat the skin with one of the above. chemicals, leaving them on the surface of the skin for a while.
Potassium permanganate (also braunstein stains). A solution of potassium permanganate is oxidized in air, forming brown braunstein (manganese dioxide), remains very persistently on the skin and resembles a tan with its color. Therefore, potassium permanganate is sometimes used by young girls and women, rubbing him on their arms and legs, thus imitating a natural tan. For this purpose, a dilute solution of potassium permanganate with a pale pink color is used. Potassium permanganate, or already produced braunstein, dissolves readily in sodium acid sulphite solution or in oxalic acid solution. Irritation may occur on delicate and sensitive skin, usually manifested by redness. Therefore, the skin stain removal treatment with chemicals should not be prolonged for too long and immediately after its completion, wash the skin thoroughly with warm water and soap., then dry it and rub it with a greasy cream.
Nicotine. Intense yellow appears on the fingers of heavy smokers, sometimes even brown nicotine stains. They can be removed from the epidermis with a mixture of hydrogen peroxide and ammonia. The stained places are moistened several times with this mixture, then it is washed off thoroughly and finally a greasy cream is rubbed into the skin. Nicotine stains can be removed with a mixture of 1 cz. hydrochloric acid and z 10 cz. alcohol. The stain removal treatment with this mixture should be carried out as quickly as possible, then the skin is washed immediately with soap and water.
Fruit. Such stains are well known to every housewife. However, removing them is not difficult, if you wipe your hands with a citric acid solution after peeling vegetables or fruit, lemon juice or a bleach solution.
Nuts. Fresh walnuts have a green color, a juicy shell containing chemicals that oxidize in the air and turn a dark brown color. This so-called. nut brown is a highly valued cosmetic. However, when picking walnuts, it leaves intense on the hands, unsightly stains. You can use citric acid or lemon juice to remove them. Another way to remove these stains is to whiten the skin of your hands by holding your wet hands over the burning sulfur, which of course requires great caution. In combination with water, sulfur dioxide vapors have a strong whitening effect (sulfuric acid is formed). This method is not recommended for sensitive skin, because sulfuric acid is corrosive. Therefore, bleaching the skin of the hands in sulfur vapor must be very short. After the procedure, hands should be thoroughly washed with soap and water, then dry thoroughly and rub with cream.
Adhesive and chewing gum. These stains dissolve easily in gasoline and stain remover.
Tar and lubricants for cars. These spots stick very tightly to human skin. First, they need to be softened with fat, then they are treated with a solvent or a stain remover. Finally, wash the skin thoroughly with soap and water, possibly rubbing with a pumice stone.
