hi all, has any of you had a problem like this?
One of my jobs has shown me a sticky residue that he calls plant sap left on his windows even after a clean. But as i have shown him it rubs off and im quite happy its not there when i leave as iv check for it, no trees or bushes near so im stumped as it seem to be a greeny yellow colour all over the windows at the back(fronts seem ok) any help or advice?

one other thing is it shows up worse when it sunny.

thanks joe

maybe he pesses up there at night after he s had a pint or two , waiting for the dog to have a crap.
well just a thought

could it be some kind of soap or polish that pure water dose not get off?
has anyone had a similar problem?

thanks joe
