Based on television shows, it seems borrowing tools from neighbors is a potential minefield. I need to power wash my front and back porches and the siding of my house. My neighbor has a power washer that he uses to do this on his house 2 times a year. In the ideal world I would borrow the power washer every year or two (I don't care if my siding and porch are a little dirty).
Details that may be relevant: I live in a highly urban area of a major US city in a block of row homes. I have no space to store a power washer, but the neighbor has a shed in his back yard. I see the neighbor regularly (he likes to sit on his porch) and we happily chat for a few minutes. We have been into each other's houses a few times.
Can I ask to borrow the power washer and if so how? I would plan on using it for a few hours and returning it clean and dry, is there anything else I should do? Is payment in beer (he drinks beer on his porch) appropriate?
