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...

Optimized sampling protocols and the development of new wipe materials can be facilitated by standardized measurements of collection efficiency from wipe-sampling. Our approach for sampling trace explosives uses an automated device to control speed, force, and distance during wipe-sampling followed by extraction of collected explosives.
FAQs
Mechanical friction helps detach biological residues, dust, and other material from a surface so the wipe can collect and remove it. The wipe must contact the area sufficiently to achieve useful removal, rather than merely spreading material across the work surface. This makes wiping technique and complete coverage important for contamination control.
Cleaning primarily removes material through mechanical action, while a premoistened wipe may add detergent or disinfectant to loosen residues or reduce microbial contamination. These effects should not be interpreted as sterilization. A surface can appear clean while still requiring appropriate biological controls, especially when experiments depend on limiting contamination rather than simply improving appearance.
Effectiveness depends on choosing a suitable wipe, using an appropriate cleaning agent when needed, and applying enough coverage and mechanical action to the relevant surface. Disposable and reusable wipes may serve different maintenance needs, while detergents and disinfectants contribute different functions. Matching these choices to the contamination-control goal supports more reliable results.
The choice should reflect the surface, the material being removed, and the risk of transferring contamination. Disposable wipes can support controlled disposal after use, whereas reusable wipes require appropriate handling so collected residues do not move to another area. In either case, the wipe and cleaning agent should be compatible with the intended cleaning task.
A basic workflow is to identify the area requiring attention, select a suitable wipe and cleaning agent, cover the relevant surface with adequate mechanical action, and manage the used wipe appropriately. Premoistened products may assist with residue removal or microbial reduction. The final disposal or reuse decision should reflect the contamination risk and wipe type.
It is particularly relevant when work surfaces or equipment could contribute to cross-contamination between samples or disrupt experimental conditions. Routine wiping helps maintain cleaner, more consistent work areas and supports biosafety practices. However, the process should be understood as part of contamination control and laboratory maintenance, not as proof that a surface is sterile.
