Yep same as Mel, we just use water and rinse at we go. I have some of the solution that is sold and you put in a foaming bottle but exactly like Mel, I found it didn't do much - water was better.
In another thread I posted in the girls raved about it (if you want info google foaming wipes solution) and they said it made everything smell better, but if i have to buy disposable wipes I buy scent free anyway so that was not an issue for me
