A cotton rag is cheaper and leaves fibres behind, and on an optical surface, a paint prep or a machined part those fibres are the problem you were cleaning to avoid. Wipers are specified for lint and for solvent resistance rather than absorbency alone. Colour coding still applies by zone. See cleaning cloths, workplace cleaning and cleaning chemicals.
