Crem1,
I whole-heartedly agree with you about the rinse. IMO and IME pure rinse water is where money is best spent. It does not take much water to properly rinse. No flooding is needed. A teaspoon at most. Any more is a waste in my experience. Being judicious with the fluids also helps the vacuum process.
I'm getting very good results steaming with distilled water. It is cheap, fairly pure, and easily found. The Peak battery water is not so easily found and I don't want to spend the kind of money it would take to ship pure water in any quantity. I have also found that 1/2 a teaspoon of white vinegar mixed with the water used in the Perfection keeps the inside clean and the left over water is clearer looking when poured out. I do this every other time I steam.
