Always leave the barrel clean.
Cleaning Up a really Big Mess
If it is going to sit at room temperature for an extended period of time you may
wish to coat the barrel with a light machine oil to prevent rusting. The oil will
need to be purged from the machine before accurate data can be obtained.
For materials that are extremely hard to clean (Polystyrene, EVA and
elastomers, etc.) solvents may be required. Never use flammable solvents on a
HOT barrel. In general however, DYNISCO POLYMER TEST does not
recommend using solvents for health, safety, and environmental reasons.
Oven cleaner (Easy-Off
) sprayed onto a cold plunger and left overnight will
do an excellent job of cleaning degraded material off of the shaft, the outside of
the die and the die retainer plate. Be careful not to inhale oven cleaner vapors.
