ot - Ever ubiquitous pee

[Nina]

Remember the thread where everyone was trying to figure out where the 
urine odor was coming from?  (Kelley, I'm sure you do).  Well, someone 
has contaminated my dryer.  I'm not sure how they did it.  I'm assuming 
they backed up, aimed and fired into the crevices around the opening of 
the door, but I guess it could be in the air filter.  All I know is that 
I've scrubbed and sprayed and scrubbed some more.  Every time I think 
it's safe to dry a load of clothes they come out of the dryer smelling 
not springtime fresh, but of fresh kitty.  Whoever marked the dryer must 
be thrilled, everything smells of their scent now.  Any suggestions?  Do 
I have to get a new dryer and house it behind chain link?
