Ensure the strongest bond possible between pipes and fittings by preparing your surfaces with Weld-On C-65 PVC/CPVC/ABS/Styrene Cleaner. This pipe cleaner effectively removes oil, grease, and dirt from the surfaces of all sizes, classes, and schedules of PVC, CPVC, ABS, and styrene. Use an applicator to apply and scrub the water-thin solvent cleaner onto pipes and fittings before continuing with the appropriate Weld-On primer and solvent cement. Weld-On C-65 may be used on FlowGuard Gold pipes and fittings and may also be used as a brush cleaner.
