Rossco, for cleaners I use L&R ultra fine cleaner and L&R #3 rinse and I have very good results. I'm planning to go Zenith when these bottles run out just to compare results. I like the watches to look factory new and so far L&R has done a rather good job but I want better. Careful with some solutions and heat (even the heat generated by the ultrasonic machine) since they are highly flammable.
