Ok, after doing a few odd jobs I ended up stinking of petrol.  I chucked my clothes in the washing machine and washed as normal - yes ladies I'm a catch!  I can do washing and everything! 
  
Anyway, when I removed everything from the machine it was left stinking of fuel.   I have run a couple of long cycles with the machine empyt and it still stinks.... 
  
Anybody know what I can do?
