1. use the manufactures recommended cleaning solution and amount, I don't know if your solution is water based but believe me a little goes a long way.
2. crank up the heat, let your ultrasonic run for about a half hour to warm up the solution and then place your parts in the ultrasonic, turn your unit on while it is warming up, that will accelerate the heating process, dont forget to turn the heater off when you call it a day.
3. forget about the lube solution.
4. dont put your slides,frames, or any other external parts in a basket.
5. wash your pcs thoroughly when you remove them from your unit, remember it's a cleaning process not a coating process, you'll want to remove all that cleaning solution from your parts and you will also want to thoroughly dry them, I'm thinking a hair dryer might be ideal for you.
6. keep your ultrasonic clean, all that residue will lay in the bottom of your unit and needs to be hosed out occasionally.
