Don't try to clean mouse-tainted areas with your bare hands. Even though a surface may look relatively clean, it probably isn't. Mice urinate when they become frightened. They may also walk through urine-saturated areas occasionally, tracking germs on the bottoms of their tiny, dirty little feet. Before you tackle cleanup, invest in a pair of latex, vinyl or rubber gloves, and wear gloves throughout the cleaning process. To avoid contaminating other surfaces, spray gloves with disinfectant periodically, especially before handling clean surfaces like doorknobs and cabinet pulls.
