Fill a small container with hot water and a small amount of soap and gently place the glass beads inside. Allow time for any grime on the beads to loosen then remove the beads from water and gently remove any dirt with a soft cloth.
For a deeper cleaning, use standard glass cleaner. Just as you would with a window or a screen door, spritz a small amount of glass cleaner on the beads and gently polish with a soft cloth.
You can also use alcohol to clean glass beads. Simply soak the glass beads in pure rubbing alcohol and dry them off.
