Hi, while sorting-out more old boxes, I've found a copy of GDW's Over the Top WW I rulebook, as well as some copies of Military Modelling. Unfortunately, they are mildewed, i.e. smelly, yet dry. How might they be restored? I gather that baking soda might be used to absorb the odour, but would there be any cheap way of killing the mould spores? I may just scan the interesting articles from the magazines, but it would be nice to be able to restore the otherwise intact rulebook. Thanks!
