I had a customer tell me about 15 years so ago that bin cleaning was going to be the new thing to do, the latest thing that was coming from some country or another but I couldn't see how it could catch on at the time, more fool me! A friend then started doing it after I mentioned it to him. He was employing people within a couple of years and he doesn't work now, doesn't need to. Does paperwork etc but that's about it. He has some brilliant trailers that he hooks the bins up to (2 at a time) and they do the cleaning, all the workers do is give them a quick wipe dry and stick a next clean due label on. He was charging £3 a bin 10-15 years ago and when he came into my street he did 9 bins in 20 mins and that was b4 he had the trailers so he did it with a pressure washer etc. I timed him from when he came into the street to when he left. if you have a lot of bins on one street the £return is fantastic as 1 person collects the bins together and returns them, the other cleans them. An established round can make a heck of a lot more than a window round. You don't have the same freedom though as you have to work hard and follow the dustmen, work whatever the weather etc. If the eBay ad is all that it seems to be, it seems a real bargain.
