I have a different regimen before play depending on whether the record was purchased new, used, or was previously in my collection. If used, I use my Record Doctor with a 4-step cycle of Audio Intelligent 15, AI-6, distilled water rinse, and then into the ultrasonic using AI-Ultrasonic fluid. If new, I go straight to AI-Ultrasonic. If after play I notice any surface noise and inspection reveals no obvious cause, before the next play I use a 3-step cycle of AI-6, distilled water rinse, and ultrasonic with AI-15. For records previously played without surface noise or recently cleaned using the above process, I use the G2 solution followed by a microfiber cloth over a record brush to remove any excess solution and dust particles.
Most relevant to OP, my ultrasonic step had been using Tergikleen but I found the AI-Ultrasonic produced noticeable better results.
