Dale,
Hum! Like David said where to start. Well run don't walk to the libary or store to by a copy of the N.F.P.A. code 96. And you are going to give a bid on Monday? I study this from of cleaning for over two months before I went to give my first bid. And I will tell you that the time I spent studing was well spent time. I would recomened waiting for your first bid. Until you have a full understanding for exhaust cleaning. This is not something that you can learn over night. I would recomend slowing down and learn everything properly. You will not only have to learn how to clean everything properly ,but also how to make a bid properly. I would look though out this BB and others to find information. Also surf the web. I learned from a veterian of 15 years of doing this line of work. And still when I went to clean my first one it took over 7 hours to do. That is a day I will not soon forget. Be patient and everything will fall in place. [tie]
