Is it better to use a window cleaner who cleans by hand or one who cleans with a telescopic brush?
Also, my window cleaner, who uses a telescopic brush, always says he'll text me when he's next in my area to clean my windows. However, he always seems to text me and want to do my windows when it's about to rain? Why is that? Surely it's pointless washing them in or just before it's going to rain.
