We were relatively lucky since my wife gets access to medical supplies for almost free and we used the individually wrapped 'gauze' (not sure if the right name, basically squares of cotton in a gauze like pattern in layers) and water. If we go out, we researched and found other brands that had little ingredients as well and took those.
We also (if in the house) preferred to wash him over using nappies (small baby, fits well in a sink and its quite quick to clean up)
