Can you wash dishes without soap?

As with so many things, there isn't one right answer.
1. In areas with very high environmental costs to heating water, cold water solutions are necessary. (And hopefully, people will plant coppicing  trees/shrubs and build a rocket stove to heat a pot of water on, for the future.)
2. In areas where drought is a severe issue, people may have no choice but to use a low water, higher soap approach to the problem of getting things clean. (and hopefully plant tree/shrubs to help reverse desertification.)
3. In places where people cannot use greywater systems and know that their water is going straight into streams and rivers, avoiding soaps/detergents that contribute to algae formation is *really* important for the environment as a whole, but many people are not so good at looking past their own front door without nudges from people higher up Paul's eco scale. In those situations, high water/low detergent/soap are likely the best compromise.
4. Within all of these options, "reduce" is step one. For example, we use colour-coded cups for family members and mostly drink straight water. I'll easily use the same cup repeatedly for 1-3 days before I consider it dirty enough to be washed. If I have just a sandwich for lunch, I'll often use the same plate for dinner by just wiping the crumbs into the compost with my hand. I *hang* my bath-towel after use - after all it got used on a "clean me", but I know people who wash their towels after every use - letting something air-dry kills the vast majority of micros without any soap or water getting involved, leave a towel in a damp heap and laundering becomes necessary.

It all comes down to the basic principles of Permaculture: observe, adapt to your situation, identify a problem and work towards solutions!

When it comes to dish without soap I spontanouesly come to think of an Autoklav like they use in hospitals to clean instruments.

Soap can be made in a low tech, traditional, eco friendly way. They make olive oil soap in the middle of North African desert countries. Soap should not be our enemy, I think..

Making soap requires energy, but burning a bit of kindling for a batch of soap that will last you a year isn't that bad, I think.

Dish washing without soap really needs old fashioned scalding hot water and scrubbing. Boil water pour over greasy dishes in a tub, let sit a bit, and scrub away.

Here's how artisans make olive oil soap in North Africa. You CAN use this stuff to wash dishes, hands, everything. My wife refuses to wash lingerie or socks with anything other than either French Savon de Marseilles, or a traditional Olive Oil soap like this...
