If instead of having wipes that you throw away when you are done, you could have the solution, a container, and washable wipes and can be re-used.  I would definetly buy a product like this as I have tried this option at home and it works well.  even if you had another container that held the dirty wipes until they were ready to be washed and then just had to dump them into the wash and be done...

Very easy system - the user wouldn't have to think of anything and it would allow users that felt that they would lose track of the wipes (much like little kid socks) to have a solution to keep track of all the dirty ones and wash them all together so none would get lost....
