Actually, I think vinegar would be more natural than wet wipes..
What I do for laundry is use 1 cup of vinegar per load, with just a small bit of detergent and it works very well. I have also used just the cup of vinegar and it works too.
For cleaning the C&C, what I've done in the past was have a spray bottle of probably about a cup again of vinegar and then fill it the rest of the way with water. I don't actually measure it out I just kinda eyeball it, vinegar is pretty safe to use for cleaning, and with tough spots, I sprinkle a bit of baking soda on there and it works wonders!
Also, about spirit vinegar, a quick google search just told me that it's just kind of a stronger version than distilled? So I would think it does about the same thing. But I could be wrong.
Hope this helps!
