i just bought a baby rocker off ebay and it smells funny, i thought it was just the cover so i took it off to wash , sprayed and wiped the plastic with normal kitchen spray and put the rocker in my bedroom, but now the whole room smells funny, its like old body odour...and its not me

A) how is it possible the plastic can smell like BO? ... and...
B) how do i get rid of the smell!??
