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...

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Rabbits possess powerful hindlimb musculature and are susceptible to spinal injury if they struggle or kick while inadequately supported. Because rabbits vary in temperament and may struggle during restraint, handlers should...

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
Manual cleaning time should be determined from the device, contamination level, cleaning method, and manufacturer’s instructions rather than from a universal interval. These variables affect how readily blood, tissue, and other soil can be loosened and removed. Applying the specified duration helps make reprocessing more consistent and supports the subsequent disinfection or sterilization step.
The cleaning action must match the part of the device being treated. Brushing or wiping can address external surfaces, while flushing is relevant to channels; joints and other difficult areas may require deliberate attention as well. Used with a compatible detergent, these actions loosen and remove soil before later reprocessing stages.
Consistent manual cleaning time supports more than scheduling. It helps standardize how personnel perform a critical pre-disinfection or pre-sterilization step, making variation easier to control. That consistency can improve quality assurance, support infection-prevention practices, and reduce the likelihood that residual bioburden remains when the device moves to the next reprocessing stage.
A standardized workflow should use trained personnel, a compatible detergent, and the manufacturer’s specified cleaning duration. Personnel then apply suitable physical actions, such as brushing, wiping, or flushing, to the relevant device areas before disinfection or sterilization. Keeping these elements aligned helps ensure that timing is part of a repeatable process rather than an isolated stopwatch value.
Device anatomy should guide how manual cleaning time is applied. External surfaces, joints, channels, and other hard-to-reach areas may not respond equally to the same cleaning action. Personnel should therefore follow the device-specific method and duration, giving attention to the areas identified for cleaning. This approach helps align physical soil removal with the device’s design.
Manual cleaning time is especially relevant when reusable medical devices must proceed through disinfection or sterilization. Reliable control of the step helps reduce residual bioburden before those later processes and supports protection of both patients and healthcare workers. It also gives facilities a clearer basis for standardized infection-prevention practices and quality assurance.
