So after a full day of cleaning, the GTS is nice and clean again. I took the Zunsport grilles off to clean out the dead flies and wasps and grikey, there was a lot. Took me about 45 mins just to clean them all out using a bug remover spray, hoover and compressed air. The rads have taken a little battering but nothing too detrimental, glad I had the grilles fitted though.
