This issue's tip comes from Lou LiCausi of Finishing Touch Floors in Brooklyn, N.Y.
Simply put, buffers and big machines make a mess when leaving the job, even if you vacuum them out. I was thinking about what might help ... I first thought of booties, then shower caps. I called a company that makes sanding accessories and asked them to make a big shower cap to cover the buffer, but they said there was no market for it, and that was that. So then the other day I saw this giant shower cap thing on a cart in a building. I asked where I could buy one, and they gave it to me. It was perfect! It's an indoor elastic air conditioner cover you can buy anywhere, like Amazon. (I'm still looking for a good option for the big machine, though.)
