What is best to choose for decontamination of the entire skin?

In order to decontaminate the entire skin, you can make a bath in potassium permanganate. This product is available in pharmacies without a prescription, e.g. https://www.gdziepolek.pl/produkty/63348/potasu-nadmanganian-proszek-do-wytworzenia-plynu/apteki To prepare such a bath, you should put warm water in the bath and pour a pinch of crystals, so that the water takes on a light pink (not dark purple) color. Such a bath should not last more than a few minutes. You can also use a liquid based on chlorhexidine, e.g. https://www.gdziepolek.pl/produkty/46386/manusan-plyn/apteki I also attach a link to a helpful entry: https://www.gdziepolek.pl/artykuly/jakie-srodki-dezynfekcyjne-i-myjace-stosowac
