Inflation has resulted in the Zimbabwe dollar completely losing its value. Banknotes are literally recyclable goods, turned into tablecloths and lampshades, for example. In the Harare slums, which are rife with crime, valuable US dollar banknotes must be concealed in clothing, which means that the notes quickly become breeding grounds for bacteria. According to money launderers, dollar bills can best be gently hand washed with Omo detergent in warm water.
