This chapter covers solvent mixtures—azeotropes or blends—which are used in non-immersion cleaning, applied to part surfaces from small-capacity aerosol cans, and serve to make some wipe cleaning operations successful. These blends extend the use of solvents from cleaning entire parts or assemblies to cleaning local surfaces. Application of solvent from aerosol cans is a significant part of the solvent cleaning industry because useful cleaning work is completed without expenditure on infrastructure, overall SHE impacts are minimized, and high margins are produced for suppliers
