A vacuum step can be beneficial depending on the cleaning and drying methods used. The VPI did perform better than either manual cleaning or the Spin-Clean which may be attributed to the vacuum drying step in the VPI. However, the ultrasonic cleaned record followed with a distilled water rinse and vertical spin drying resulted in the cleanest surface. The important step is spin drying on the spindle assembly in a vertical position. As I stated in my previous post the ultrasonic cleaned surface had between ~95 to 98% contamination removal which corresponds to ~2 to 5% surface contamination remaining. It would be near impossible to remove more contamination with any method unless working in a clean room environment.
Humminguru Nova
I’ve assembled more or less a decent analog front end. I have a few hundred records in my collection that consists of new and old vinyl - mostly mint or near mint. Now I have been buying new vinyl recently. I use Knosti Disco Antistat to wash records - one for wash, one for rinse. The records air dry.
Would a Nova be a significant step up from the Knosti? Would it be effective with new vinyl? Any reason I shouldn’t get it?

@lalitk agreed. I’m also extremely impressed with Craft Recordings. Bought a Bill Evans “Sunday At The Village Vanguard” as well as Ron Carter “Where?” and Art Blakey “Caravan”. All are excellent quality. |
thanks for the caution, the idea came from another discussion, do you think 2% glycol by volume is risky? https://forum.audiogon.com/discussions/kirmuss-ultrasonic-vinyl-cleaner?highlight=kirmuss excerpt: "lnitm OP170 posts Elliottbnewcombjr Do you think adding something to my mix to get a positive/negative charge would be beneficial? If so, add how much of what yes. Add 2% per volume of propylene glycol to mix. In otherwords approximately 1 Oz per gallon of propylene glycol. It’s what is in the Kirmuss solution that gives that charge to attract the bubbles to the vinyl. Add in the tank with distilled water." |
I don’t know if 2% is risky, but I see no reason to include something that is difficult to remove and potentially can leave a sticky residue on the record surface. Polypropylene glycol is a neutral polymer and has no charge although in water the polar oxygen atoms and hydroxyl end group atoms can have a weak attraction for water molecules and other cations. I doubt that this would have a significant effect on the cleaning efficiency in an ultrasonic bath. |
I was researching record washing solutions and MoFi Ultra Record Wash is highly rated and is designed for ultrasonic cleaners and is recommended for Degritter. |
