I have no idea yet about older child poo, but here is what I am using for my newborn and it works AWESOME!:
For the wipes, I cut up old t-shirts into small squares. Â It's super cheap, plus they don't fray in the wash, and you just toss them in the wetbag/washer with the diaper laundry. Â And for some reason, all but one of the t-shirts I have cut up roll themselves into scroll-shapes in the laundry which makes them look really nice and are easy to store that way. :) Â For now, with breastmilk-only poo, I just wipe him and toss everything into the dry diaper pail, and I haven't had any laundry issues yet (he's 3 weeks old.) Â The solution I'm using is to put a bit of aloe-vera juice in a Wilton plastic icing bottle (like a Peri bottle), then a few drops of grapefruit seed extract, then a few drops of essential oil of grapefruit, then fill to the top with distilled water (Brita filter) and keep in the bottle and just squirt a cloth wipe before using. Â I hold my hand around it for a few seconds to make it warm up... easy enough.
When I'm going out, I put several scrolls of diaper wipes (or squares or whatever) into a ziploc bag and squeeze enough solution into the bag to saturate the wipes. Â Easy to use for diaper changes, and can also be used to wash hands when out and about.
So far so good... I am so glad I am using disposable wipes... I agree than when using cloth diapers, it makes more sense, and is SO much easier to just have everything washable!
By the way, I agree with whoever said that I would never dunk a diaper in a public toilet... way too many yuckies in there... but that's just me! ;)
