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...

The lack of a well-defined procedure that consistently cleaned coupon surfaces was identified as the major contributor to low and variable recoveries in cleaning verification. This manuscript describes the correct protocol of cleaning stainless steel coupons.
FAQs
Effective cleaning depends on matching the treatment to both the plate material and the experiment. Liquid removal first limits remaining sample volume, rinsing carries away residual reagents, and detergent or disinfectant treatment can loosen deposits or reduce biological contamination when appropriate. This sequence helps protect the plate, prevent carryover, and maintain suitability for reuse or disposal.
Detergents and disinfectants serve different functional purposes within a plate cleaning protocol. A detergent is used, when appropriate, to help loosen residues, whereas a disinfectant is selected to reduce biological contamination. Neither should be added automatically: the choice and conditions depend on the plate and experimental context. Correct selection supports safer handling without compromising the plate’s intended disposition.
Carryover occurs when material from one experiment remains available to affect a later workflow. Removing liquid, rinsing residual reagents, and addressing biological contamination reduce that risk. The importance is especially clear in cell culture, biochemical assays, and analytical workflows, where leftover samples or reagents can compromise consistency. Cleaning therefore supports reliable results as well as laboratory safety.
A basic workflow begins with liquid removal, followed by rinsing to clear remaining samples or reagents. If suitable for the plate and experiment, detergent or disinfectant treatment is then used to address residues or biological contamination. The final handling decision should reflect whether the plate is being prepared for reuse or disposal, while careful handling limits exposure and protects equipment.
Plate cleaning is particularly relevant after workflows involving cell culture, biochemical assays, or analytical measurements. In these settings, residues can create carryover between samples, while biological contamination can affect handling and laboratory conditions. Applying a consistent protocol helps preserve plates when reuse is appropriate, supports dependable downstream work, and reduces avoidable exposure during cleanup.
In biology, the protocol must balance cleanliness with the condition required for the next use. A treatment strong enough to address residues or biological contamination may not be appropriate for every plate material or experiment, so the sequence and conditions require judgment. This material-sensitive approach helps maintain experimental consistency while supporting equipment protection and safer laboratory practice.
