Cleaning Procedures
It is recommended that HFE-347 be used in a vapor degreaser to optimize cleaning efficiency, economy, and emission control. Cleaning procedures for HFE-347 are quite similar to other solvent products. The procedures consist of immersing a workload into the boiling solvent, rinsing or spraying with cool solvent and drying in solvent vapor.
