It can, but hot water works better because it helps to dissolve grease and hardened food better than cold.
Warm water is a better cleaner because cold water fuses the stain even more so to the fabric, where as warm water draws the stain away from said fabric.
Although the FDA mandates warm water for those in food service, the CDC says any temperature is fine, so it's a bit of a contested subject.Heat is known to kill bacteria, but the temperature and duration of exposure required would seriously damage human skin, so that argument for warm water is a bust. Additionally, some advocate for washing in cool water because it uses less energy and is therefore more environmentally friendly.Anyway, no matter the temperature, washing your hands thoroughly with soap for 20 seconds is good practice.

The nine steps in proper handwashing are: Wet hands with clean, running water (warm or cold). Apply soap and lather well. Rub hands together to create a lather, ensuring to clean between fingers, under nails, and the backs of hands. Scrub for at least 20 seconds. Rinse hands thoroughly under clean, running water. Dry hands using a clean towel or air dry them. Turn off the faucet with a towel if possible to avoid recontamination. Dispose of the towel properly if used. Use hand sanitizer if soap and water are not available, ensuring it contains at least 60% alcohol.
