GS-34

Cleaning and Degreasing Agents

Our standard for cleaning and degreasing agents establishes environmental requirements for agents suitable for cleaning soils in production and maintenance applications. Suitable agents do not include those for specialized cleaning/degreasing operations such as the removal of paints, sealants, rust, and adhesives; handwiping parts; preparation of surfaces for electroplating, organic coatings, and parts testing; or the cleaning of hydraulic components, medical supplies, electronics, and optics.
