Have a property with some high three storey windows where the sills get piled with housemartins poo. What i do is swap the brush over to one of those magic rubber ones with a built in squeegee and scrape it off. Had my pole at 35' and did the job untill the top section came off whoops! Left dangling from the sill, managed to snooker it back on an pulled the hose taut - could have been expensive. :
Anyone else have a confession of stupidity?
