A lab bench needs cleaning before and after each experiment. Cleaning a lab bench removes any dangerous substances and keeps the area safe. It also gets rid of materials that could contaminate samples in sensitive experiments, helping you achieve more accurate results and conduct successful experiments. Using both bleach and ethanol to thoroughly clean a lab bench destroys even small particles like traces of DNA.
