Abstract
Synthetic resin articles to be printed, plated or coated are cleaned prior thereto by carrying the articles into a cleaning zone where they are contacted with an aqueous detergent solution which is allowed to flow upward and to which an ultrasonic wave is applied, carrying the articles from the cleaning zone to a rinsing zone where they are contacted with warm water which is allowed to flow upward, carrying the articles from the rinsing zone to a dipping zone to contact them with more fresh warm water which is allowed to flow upward, and then pulling the articles up slowly from the dipping zone to drain off the water attached to the articles.
