Anyone offer any advice on this. My windscreen is like a 'flies
cemetry' and all the 'specialised products' aren't any good.

Anyone got any tips on best way to remove the poor blighters.

I got chatting to my local hand wash lads and they said that they used
DFR solution and they offered to give me some for my washer bottle. I
suspect that it must remain in contact with the screen for a while
before the flies can be washed off though.

(I presume that DFR stands for dead fly remover)
