How to clean out Tygon?

[KingLouisVI]

I just scored 6ft of Tygon for free, but since its a bit old, its got some brown/white residue.

Whats the best way to clean this stuff out?

Try running vinegar or iso alchohol through the tubing and then letting it sit . Make sure to flush the tubing after with distilled water.

That dont work, buy some "simple green" cleaner from dept. store or home depot and run it thru, stuff works wonders
