HAd a patio and path clean to do yesterday. Whilst doing it, over the road a chap turned up and started to do the neighbours concrete drive. With a tiny karcher. We finished and I went over to say hello, and where he had CLEANED the concrete it was stripe city. It looked a right mess. I asked if he was going to go over it and he replied " Nope, why?"
Get the right equiptment, and make an effort. This chap couldnt give a monkeys. We always do a really good job and take out time but with this vebra drive over the road it made ours look even better.
