The soap sonic is done in a tank with ultrasonics placed in the cleaning bench in the changing room. The cleaning solution is DI water to which a little diluted Triton X-100 is added. Triton X-100 is a nonionic detergent which is metal ion free. This detergent is added to reduce surface tension and thus help removing particles from the samples to be cleaned.
