go to ur local hardware store & look for some Concentrated Germicidal Cleaner. i had over a foot of Rat Cr@p
in my bus when i got it. i even left the bus outside for 2yrs b4 bringing it into my garage, i tried several products & nothing would get rid of the FUNK
untill i used that stuff. with one good soaking of this stuff the smell was gone forever.....joe
plus this stuff will kill all the "bad" stuff that comes w/rat & mice poop.......
