Oh yes, I hate it. Has anyone found anything that will shift it instantly that I can carry in a hand sprayer?
I'm in rural Wales and do a lot of dairy farms. With the inevitable poo that comes with dairy farm there are plenty of flies. Their poo on windows and white uPVC frames is difficult if not impossible to get off even reasonably quickly, even with a scourer and TFR. And there's a lot off it.
So, has anyone got anything they have used sucessfully?
