We are new to geocaching, but love it so far. 6 finds in first week . I was wondering about all the (Sorry if I ofend anybody) trash that we find in the caches. Broken junk toys, an old baby pacifier, old batteries (Complete with the gritty dried crud on it). Is it accptable to clean this stuff out? Not sure why folks leave stuff like this to begin with, but hey---there may be a reason. Thanks in advance.
