Solvent wipe, immersion or spray

The process is not as efficient as vapor rinse, solvent wipe, immersion, or spray, but it is suitable for many surface preparation applications and pretreatments. One or a combination of these techniques may be used. A large number of solvents are recommended. Solvent wiping is the most portable and versatile of these methods, but is also the least controllable. There is always a danger of incomplete removal of soil, and spreading of soil in a uniform manner, causing its presence not to be readily visible, and contamination of a surface with unclean wiping materials.

Selection of the solvent should be dependent on the plastic being cleaned. Certain solvents will aggressively attack certain polymeric surfaces, causing the surface to deform or exhibit stress crazing. Substrates can be wiped or sprayed with degreasing solvents, or they can be immersed in an agitated solution for about 5 min. 

Solvent clean, preferably by vapor degreasing (avoid immersion and wiping, unless these steps can be followed by vapor rinsing or spraying)... 

Solvent cleaning —Immerse, spray, or wipe in either of the solutions given in Tables 7.18 and 7.19, which degrease the surface and leave a dull finish to the paint...
