@tomic601 , Records always maintain a slight static charge which attracts dust. New records will always have some dust on them. Just pull them out of the sleeve and within seconds some dust will collect. This incidental dust is easy to sweep away as it lies on the surface. What is important from a sonic perspective is contamination in the groove that can not be swept away, it has to be dissolved. You will not see this on your filter. What you see on your filter is undissolvable dust. Sources of contamination in the groove are things like cigarette smoke (tar) and cooking fumes (oil). A record that is contamination will leave a residue on the stylus. I have played thousands of new records and have never seen one leave a residue on the stylus. Because I use a sweep arm dust is kept away from the stylus.
In Short, I disagree in the extreme that new records are contaminated and need to be cleaned. Just sweeping the incidental dust out of the way will do.
I just ordered a Clearaudio Double Matrix Pro to clean a bunch of old 78s I was given. I will do a study on new records. I can record records on the computer and can compare before and after cleaning files to see if there is any improvement in background noise after cleaning new records. I will report on the results probably later in the Summer.
