Flushing rear brake lines?

I picked up a donor rear axle and when turned over, the brake lines oozed yellow/gray fluid. I have 2 options. Replace the lines and cylinders from the old axle, or flush and clean the donor parts.
So how can a brake line be flushed effectively and easily? Squirt mineral spirits through them until they run clean?
Never have had to do this before because I tend not to drive through deep rivers.

PS: There was no water in the diff case, only the brake lines.

Assuming the steel lines are otherwise in good condition, I'd flush the steel lines with brake cleaner and replace the rubber sections. Mineral spirits might work; I've never checked to make sure that brake fluid dissolves into mineral spirits though and brake cleaner definitely works. I'd also either replace the wheel cylinders / calipers or at least take them apart for a good cleaning and new seals.

I think you should replace all of the brakeparts that are on the "new" axle including the brakelines its easy now when the axle is not on the jeep.
Never cheap out on stuff that has to do with your brakes, brakeparts are cheap.

I've decided to keep my lines because I know they are good and replace the cylinders with new. They aren't very expensive.

I like the copper/nickel lines.
