In any grid down situation, many of us are going to find that our hygiene suffers. Now I have been dirty for extended periods of time before and it is not pleasant. Not being able to clean up can lead to illness and poor moral particularly among inexperienced people.
If you are in a situation with limited water and still want to clean up, you can take a shower as follows. Stash a new 1-gallon weed sprayer with your preps. You may want to paint it black so it will heat up in the sun. Wet yourself or have someone spray you just enough so that you can soap up. Once you have lathered up, use the sprayer to rinse off. You should be able to take a shower with less than a gallon of water.
Sun washing clothes – If you have a real water shortage, shake your clothes out and spread them out in the full sun. The more the clothes are exposed to sun, the better. Sun washed clothing will feel cleaner and smell better. The ultraviolet radiation will kill off the bacteria that live in your sweat and dead skin cells. Do not forget to sun wash your sleeping bags and bedding
My mother said that in experiences in England during WW2 that the inability to clean up became a big issue. Many people found this hard to deal with. So stock up on your soaps and other hygiene supplies.
