Bad quality vinyl will pop and click brand new even if cleaned with an RCM. It's because the vinyl itself is contaminated and there is nothing you can do to remove what's embedded in the pressing. I do have many albums that sound incredibly quiet, however, so it is possible. Most surface noise probably comes from damage done by incorrect set-up or simple carelessness. Part of the hobby, if you ask me, and well worth it.
Vinyl cleanliness
How many albums do you own that don't have ANY pops or clicks from beginning to end after a thorough cleaning? I have yet to find one, and was curious as to your results.
And yes, I know how to clean my albums ;)
