=Basics=
*The Removal of Surface Contaminates from Parts
*Although it can be as simple as "wiping something down" or rinsing something off, this typically refers to the practice as a part of a [[Quality Control Plan]] / [[Lab Protocol]]
*Certain processes are more sensitive to surface contamination than others
**Painting, [[Powder Coating]] , and [[Electroplating]] are suseptible despite not being that "high tech" of processes
**[[Microfabrication]] and [[Micribiology]] are so sensitive that they must be preformed in [[Cleanrooms]] etc
*Note that when cleaned to very high levels, [[Flash Rusting]] becomes a concern with certain metals, and thus either there should be little gap between the cleaning process, and the next manufacturing step, or special precautions should be taken, such as applying a temporary [[Gumming Solution]]

=Methods=
==Mechanical==
*Scrubbing/Wiping etc
**Can get rid of "bulk contamination" ; still leves behing a thin film or best case scenario a [[Monolayer]]
**Thus it will still fail the [[Water Break Test]]
*[[Media Blasting]]
**Can clean off stubborn contamination and even get to a level passing the Water Break Test
**Short of [[Dry Ice Blasting]] , it is an [[Abrasive]] process and thus has impacts on surface finish, and can not be used on thin parts
*[[Surface Preperation]] (Surface Prep) for Painting etc is essentially this

==Chemical==
===Solvents===
*Dissolves Contaminants
*Polar for Polar Molecules, Nonpolar Solvents for Nonpolar Contaminants
**Most dirt and grime is nonpolar, hence most Cleaning Solutions focus on this, water works well otherwise in many cases
*Misc Scales for "Solvent Effectiveness" although the nuance of each job makes these only marginally useful
**[[Kauri-butanol value]]
*Note that even with a Perfect Solvent, Flow and/or Mechanical Action is needed to remove the Solution of Dirt+Solvent before it Evaporates
*Processes like Spraying or [[Vapor Degreasing]] increase the effectiveness of solvents especially
*[[Dry Cleaning]] processes such as using [[Supercritical CO2]] are also in this category, more complexity, but more gentle on certain materials

==Chemical Reactants==
*Certain Cleaning Solutions can be used to turn Residues that won't dissolve, or be scrubbed off into other chemical compounds that can be
*For instance, Bleach can react thin Hydrocarbon Layers allowing the underlinging material to pass the Water Break Test
**Even [[Comet Cleaner]] works quite well for technical applications!
*Various Acids, and [[Pirranah Solution]] among other things also fit in this category

==Misc==
*[[Plasma Cleaning]]
