Due to fragile nature of antique jewelry I would not recommended ultrasonic or high power steam cleaning, just soap and water with no brushing is best. Please check photos carefully, all my Items are either Estate, Vintage or Antique. Most are not new Items and will have typical age appropriate wear.
