I don't think there is a good way to clean pee off cardboard. Also, once cardboard gets wet, it will be damaged pretty fast.
There is a whole business in reproduction boxes. There's a guy in the orange hall at York who had a whole multi-table setup. It was mostly postwar boxes if I recall.
I have had problems with the new Lionel LCT boxes. The glue doesn't hold on most of them. I've tried re-gluing with not so good results. I haven't tried Paper Cement yet. Maybe that would work better.
