ill have a look exactly what its called but it was gunk degreaser in a green tin but be careful with it on painted surfaces as mine ended up with white streaks through leaving it on to soak too long while i washed the rest of the car. it t-cutted off though luckily. but i used that, hot soapy water, & just general scrubbing until my arm went dead. its that waxoil **** they get sprayed with when bought new. supposed to protect it but it just attracts dirt & is a twat to get off.
