just give the old 'Got feck all else to do mate'... or if they drop the ole '...ya can wash mine if ya like'....just bounce 'nee point, however many times ya wash s**te, ya never get it clean'.....soon shuts em up
i don't wanna sound dense, are the alloys white? can't wuite tell?
dnt worry about it mate every sunday i get the same s**t off the neighbours "do mine next?" "you will wash that away on day" just take satisfaction at there buckets. Bloke next door cleans his 57 plate vauxhall meriva with a green scrubbing pad should see the state of it
