Best way of cleaning non-organic fruits and veggies for juicing?? Ideas please!

Hi,

I'd like to know: What is the best way to get the least amount of pesticides etc. in your juice?

- Where do you clean the vegetables with? (Does anybody know a good cleaning solution? E.g. like purified water with something in it?)
- Which vegetables/fruits should you peel?

Tips please.

Thanks a bunch!!

Love,
Lisa
