MG MGB Technical - Cleaning Brake Lines

I am renewing the front and rear brakes of my 19712 mgb roadster. I have a new master cylinder, rebuilt calipers, new wheel cylinders, and two new pieces of brake line to the rear brakes. I still have the main brake line from the master cylinder to the front and rear brakes, though, and I would like to clean it to avoid contaminating the rest. I have heard alcohol is good to use. What kind of alcohol? What is the best way to do it? Any help will be appreciated. Thanks. Curt

Why won't you replace all the lines, since all the rest of the stuff is new?

Curt: If you are going to use the old lines, I would flush them out with brake fluid. Alcohol may not be good for flushing because you may not get all the alcohol out and it loves moisture and has a lower boiling point than water. The following site has some very good brake overhaul and theory information. It also covers the pros and cons of switching to silicone fluid.
