HIRUDOCLEANER is a specially formulated recipe for sterilizing leeches. A leech should be sterilized for 5 minutes in a solution made by dissolving one tablet of HIRUDOCLEANER in 2 liters of water. Now the leeches are ready to be applied. Components of the preparation are harmless for leeches and effectively inhibit crucial enzymatic reactions in cells of bacteria, viruses and funghi. By triggering protein denaturation, HIRUDOCLEANER effectively destroys microorganisms which might be found on the body of a leech and its jaws as well as in its sucker and mouth opening. The solution remains in effect for 30 minutes and is entirely biodegradable.
