@Chimi_Chuang_Tzu @Tfmonkey Cloth wipes for when toilet paper runs out. I have baby spit-up towels. They're hypoallergenic & soft. Couple this with a way to scrub laundry -- if you'll have a bath tub or sink handy, you can hand wash in those. If you aren't sure you'll have those, get some plastic 5-gallon buckets & assign one to laundry. You can sometimes get them for free. Might also invest in a washboard, but those can get pricey. Definitely buy a couple of packs of rubber dishwashing gloves.
For sure, I have a supply of wet wipes I normally use and stock.
I'm on a well water system so total control of water but good idea, thanks.
@Chimi_Chuang_Tzu @Tfmonkey Bonus:
For water, consider that some people in your group may be allergic to iodine, so you'll need to be aware that some water purification drops / tablets use iodine.
If you already have those, I wouldn't just toss them, but just be sure to have alternative ways to keep water clean (chlorine tablets, for example).
