Tips when using ASACLEAN N-Series Mechanical Purging Compound:

arrow No soak time is required for an effective purge.
arrow For maximum performance, ASACLEAN should not be diluted with other materials.
arrow ASACLEAN mechanical grades work best with maximum agitation. Use the maximum safe screw speed with maximum safe back pressure, while keeping the screw in the forward position.
