Five products were selected from previous trial based on effectiveness. One product was diluted to 10% using DI water and the other four were used at full strength in 600 ml beakers. Each solution was heated to 130 F in a Crest 40 kHz ultrasonic tanked filled with water. The solutions were degassed for 5 minutes.

Five stainless steel rings with lacquer finish and coated with Jackonslea Grey Color 305 A (1344-28-1) were cleaned in each solution at 1-minute intervals using 40 kHz ultrasonic cleaning. Rings were rinsed for 15 seconds in 120 F tap water and dried using compressed air at room temperature for 30 seconds. If the rings were not completely clean after the initial 1 minute, the rings would be cleaned for another 1 minute. In addition, if the rings were not completely cleaned after 5 minutes, cleaning would be stopped.

All five products need more than 1 minute to clean. No cleaner needed more than 4 minutes. The table lists the observations for each ring cleaned at the various time intervals.
Order of observations from worst to best: Not clean<Almost clean<Nearly clean<Clean

All five products will be tested on the un-lacquered/dirty rings under the same conditions.
