Source: Vy M. Dong and Daniel Kim, Department of Chemistry, University of California, Irvine, CA Organic synthesis is about transforming a readily available reagent into a more valuable product. Having clean glassware is crucial for the efficiency of this process. Dirty glassware can potentially affect the reaction and make isolation of the final product more challenging. Thus, a synthetic chemist must keep the glassware spotless. The methods described here will detail different glass cleaning...

Keeping the microscope optics clean is important for high-quality imaging. Dust, fingerprints, excess immersion oil, or mounting medium on or in a microscope causes reduction in contrast and resolution. DIC is especially sensitive to contamination and scratches on the lens surfaces. This protocol details the procedure for keeping the microscope clean.

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease. Cleaning The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Source: Morgan, E., et al. Selective Cleaning of Wild Caenorhabditis Nematodes to Enrich for Intestinal Microbiome Bacteria. J. Vis. Exp. (2021)This video demonstrates a protocol for isolating intestinal bacteria of interest from wild Caenorhabditis worms. The worms are first starved and washed to eliminate residual feeding bacteria from their surface and intestinal lumen while preserving the target microbes. After surface cleaning and multiple crawling steps, the worms are dissected to extract...
FAQs
These factors work together rather than independently. Cleaning agents help remove soil, mechanical action assists in detaching residues, and adequate contact time allows the agent to act on the contamination. Water quality and temperature also modify performance, while the material being cleaned can affect how successfully the process removes residues. Poor control of any contributing condition can reduce the final result.
Disinfection and sterilization depend on effective prior cleaning. Residual soil or organic material can remain on a device or surface when cleaning is inadequate, making later processing less reliable. Cleaning quality therefore functions as a prerequisite for these controls rather than serving as a substitute for them. Maintaining this distinction helps healthcare teams reduce contamination risks during patient care.
Performance depends on the combined effects of the cleaning agent, mechanical action, contact time, water quality, temperature, and the device material. A condition that works well for one surface or instrument may not produce the same result elsewhere because materials can respond differently to the cleaning process. Consistent control of these variables supports more predictable removal of residues.
Visual inspection provides a direct check for remaining visible soil, while tests can detect residual contamination that may not be apparent by sight. Using these approaches gives quality monitoring both an observable and a test-based component. Their results can help identify inconsistent processing and support standardized cleaning practices for instruments, devices, and clinical environments.
A standardized approach should specify how cleaning is performed and how its performance is monitored. It should account for the cleaning agent, mechanical action, contact time, water quality, temperature, and the material being processed. Applying the same controlled approach across relevant tasks improves consistency and helps connect cleaning results with subsequent disinfection, sterilization, and infection-control objectives.
It is especially important when instruments require further disinfection or sterilization before reuse. Inadequate removal of visible soil, organic residues, or other contaminants can compromise the reliability of those later controls. Monitoring the cleaning result during reprocessing helps support safer instrument handling, reduces opportunities for cross-contamination, and contributes to consistent patient-care practices.
Reliable cleaning reduces the contamination burden on clinical surfaces, devices, and instruments before they are used or processed further. This supports effective disinfection and sterilization and helps limit the transfer of contaminants between patients, equipment, and care areas. In practice, standardized procedures combined with quality monitoring provide a structured way to strengthen infection-control efforts across healthcare environments.
