Premier, no. I don't know about the Microcare. Premier is used to get mold release agents off of new vinyl and does little or nothing for all of the other crud you find on used records. It should always be followed by a good lp cleaner and a rinse.
If you really want to cut down on the cleaners get yourself a cheapy steamer. Steam the LP, followed by a good cleaner, vacuum, apply a good rinse, then vacuum again. That is the process I follow. It is amazing how much difference steam cleaning makes.
