Undecided Question

How do I care for my face without skin products?

I'm having a terrible time taking care of my face, zits keep popping up everywhere with bumps and my face is scarred and discolored and red everywhere.
I really really don't want to see professional help, just leaving it at that.

My main concern is whether I can take care of my face without products. As well as these questions:
1. Can I touch my face with my hands when they're clean?
2. Should I wash my face with cold or hot water?
3. Is hot water damaging?
4. Should I splash water on my face, I feel like it doesn't help at all, or should I soak a washcloth and scrub my face?
5. Is using a washcloth good or bad?
6. What happens if I don't pop a zit? Does it just go away?

Thanks.
