How can I use iodine to avoid traveler's diarrhea?
For disinfection with iodine, use either tincture of iodine or tetraglycine hydroperiodide tablets, such as Globaline or Potable-Aqua. These disinfectants can be found in sporting goods stores and pharmacies.
Read and follow the manufacturer's instructions. If the water is cloudy, strain it through a clean cloth and double the number of disinfectant tablets added. If the water is very cold, either warm it or allow increased time for the disinfectant to work. Adding a pinch of salt or pouring water from one container to another will improve the taste.
