I use a NeilMed nasal rinse. We keep our water heater set up pretty hot. I flush out the bottle and snorkel with such hot water that it makes my hands sting. I don't think amoebas can live in water that hot. I then add the saline packet and hold it under cold water until cool enough to use. Sometimes I add 6 drops of Lugol's Iodine if I have been around people with germs.
