Burnt Ice Cream?
My "Hot Water Heater", a 5 gallon giant spaghetti pot for my shower system, also serves as clothes washer for socks, undies and t shirts on the rare occasion I need to do such items. (I have about 50 spares in the trailer at all times just to avoid this chore
I boil the items, swish em around with a big old spoon and mosh them in the sink, then rinse and mosh simultaniously.
They don't smell Powder Fresh, but they also don't smell like anything. They are clean.
Jeans and sweatshirts are another story. Jeans, you just have to rinse and hope for the best and a proper washer as soon as you can get to one. I always wear a t shirt or tutle neck under my sweatshirts, so they never come in direct contact with my body stink, so they actually do quite well with a hot rinse and wrestle.
Now for my dust ruffles, I place them all around the outside of the trailer like a skirt, and hitch up. Drive as fast as I can thru big puddles a few times. Power blast.
