Record cleaning and care

Yes, not really, it depends.
What is the condition of the record?- cleaning won’t change damage; some phono cartridges and phono stages will also emphasize surface noise.
It also depends on the level of cleaning you are comparing against ultrasonic.
I use ultrasonic for new, unmolested vinyl, but for old records (and some new ones), I still use conventional fluids and vacuum (Monks) in combination with ultrasonic.
I think many people adopted US originally for convenience. I do think it adds something to the cleaning process, but if you are buying old copies, I have found that it is not sufficient. It is a wonderful complement to a good basic cleaning regimen though.
Others may have a different view.

Nothing removes audible scratches or repairs groove damage, how much of that you will hear and to what extend will depend on your particular table/cartridge set up.
Yes, quite a number use ultrasonic machines, some in combination with traditional vacuum machines. Records can be made very clean.

Well the pops and clicks I'm hearing sound from more like dirt or static as I can't see scratches with the naked eye in particular. Some are brand new records, some are old but in very good shape with appear no scratches. I have an EAT C Major with Ortofon QC Blue cart. I've been told that cartridges that  " remove " or " lessen " pops and ticks are rolling off the highs. 
But my question is if a perfect or very clean record and using Ultra Sonic and Vacuum RCM can pops/clicks be virtually eliminated or is that just inherent with vinyl no matter how clean ?

Every copy of every record is different. I have many, many records that play beautifully, no noise, pops, clicks, etc.  Whether you can eliminate those from a record by cleaning is not guaranteed since some of the problem records I have encountered over the years had no visible indicia of damage. Some records will play quietly with minimal (or even no) cleaning;  this is so even if a record has surface scuffs or hairlines; others-- noise, whether ticks or groove chew, even if pristine to the eye no matter how much you clean. 
The absence of clicks and pops due to the stylus/cartridge and phono stage is not necessarily a reflection of a less revealing set up. Read some of the posts from Ralph Karsten (@Atmasphere) about phono stage design and clicks and pops as an example. 

Record cleaning is a good idea, even with new records.  I buy a lot of used records and had gotten a bit lax recently, not cleaning them all.  The shop I buy most of them from cleans most of their records (except the bargain bin stuff) with a VPI 16.5.  I have one at home, and when I buy records from other sources I always clean them. 

Long story short, I was listening to something I bought there with my girlfriend and it looked super clean and shiny, but was really noisy.  She said "you should clean that" to which I responded "It's already been cleaned, it won't do anything".  To my surprise, it was noticeably quieter after I cleaned it.  Needless to say, now I'm cleaning EVERY record before I play them.

I've been using the Audio Intelligent Vinyl Solution Premium One-Step Formula No. 6.  I don't do any rinsing after cleaning.

Cleaning won't fix a worn or poorly pressed record, but it can do wonders for some of the second hand (and new) records you buy.
