The process removes buildup from absorbent materials. Buildup consists of minerals, detergents, or other residues that reduce absorbency and contribute to odors. An example of when the process is needed is when cloth diapers consistently leak despite proper fit and laundering.
Effectively removing residue from these items restores absorbency, thereby minimizing leaks and potential skin irritation in infants. Historically, this practice has extended the lifespan of cloth diapers, offering economic and environmental advantages over disposable alternatives.
