The local seagulls have emptied their bowels onto my car (again) and the stuff has set hard on the paintwork. Apart from elbow grease and lots of hot soapy water, is there a proprietary compound one can use to soften and dissolve the crap? I'm wondering if drain-unblocking fluid (the stuff that dissolves the blockage) might work, but I don't want to damage the paintwork. Any pearls of wisdom out there?
It should rain later today so that might make things easier to shift...
