Reviewed Cleaning and Degreasing Operations Options
Following are a list of options that have been reviewed by pollution prevention specialists. These options have worked at other facilities and may work at yours.
reduce solvent evaporation
|Increase the freeboard height to significantly reduce solvent evaporation.|
automatic parts lift
|Install automatic parts lift on vapor degreasers|
Use drain racks
|Use drain racks to reduce dragout.|
use rotating rack.
|Drain parts using a rotating rack.|
|Determine whether parts need to be cleaned.|
Use rust inhibitors and lubricants
|Use easy-to-clean or no-clean rust inhibitors and lubricants|
Review handling process
|Review the handling process of the parts to determine why parts are getting dirty and take action to prevent it from happening in the future.|
|Purchase clean input clean|
Use elbow grease
|Use elbow grease. When possible, clean by brushing and wiping.|
Use aqueous-based cleaners
|Use aqueous-based cleaners|
|Use solvents with a low vapor pressure and high flash point.|
Use citrus or terpene cleaners.
