Cleaning is broadly achieved through mechanical action and/or solvent action; many methods rely on both processes.

Washing, usually done with water and often some kind of soap or detergent

Pressure washing, using a high-pressure stream of water

Wet cleaning, methods of professional laundering that avoid the use of chemical solvents

Abrasive blasting, typically used to remove bulk material from a surface, may be used to remove contaminants as well

Acoustic cleaning, the use of sound waves to shake particulates loose from surfaces

Ultrasonic cleaning, using ultrasound, usually from 20–400 kHz

Megasonic cleaning, a gentler mechanism than ultrasonic cleaning, used in wafer, medical implant, and industrial part cleaning

Carbon dioxide cleaning, a family of methods for parts cleaning and sterilization using carbon dioxide in its various phases

Dry cleaning of clothing and textiles, using a chemical solvent other than water
