Irrigation by saline or destilled water is the best way of cleaning out the wound. Minor scrapes and cuts can be cleaned out with iodine and alcohol. Burns only get water or sailine. Iodine becomes a problem if somebody is allergic to it. Althou I regullary see use of iodine to clean up a slash wounds (hospital) it does follow the irrigation by saline first. I personally have no problem with using it on abrassions or any smaller wound.

The thing is that we have space problem and if you can carry enough water to irrigate the wound than you have nothing to worry about. Unfortunatelly due to space limitations I personally dont have a comfort of carrying bottle of saline and bottle of destilled water and bottle of betadine. Sterrile trauma dressing and bleading control is all you get before transport. Unless your wouldn is small enough that alcohol wipes I have wll clean it up.
