If this is...- Neil.Antin

Reduce the DG fluid use to 1-ml and you will get much less foam. Unless their formula has changed from what I last saw (someone shared the MSDS that listed the composition; but only in ranges and whether it was complete is unknown), 2-ml is too much, and it will leave residue. There is a very...- Neil.Antin

Ultrasonic Cavitation & Cleaning Explained
Edit - Delete - What is the depth of the tank from the water level to the bottom of the tank? I missed your prior edit showing that the record is ~1.5" from the bottom. Did you reclean the records with your vacuum-RCM and then recheck the record? What are the records name/label/age you are...- Neil.Antin

Ultrasonic Cavitation & Cleaning Explained
No there is not a big difference between them. The 50-ml of 70% IPA = 35-ml 100%/1400-ml = 2.5% - so that's right on. The first row for the DG is 1-drop of 100% concentrate, and the para XIV.8.5 above the table says "However, the inexpensive and readily available Nalgene Dropper Bottle...- Neil.Antin

Ultrasonic Cavitation & Cleaning Explained
Tim, You do realize that my book references John Fuchs and some of his articles. If you use the search function and type in Fuchs, you will get five hits with either direct links to his article or reference to an article that has a number in parenthesis that cross-links to list of references...- Neil.Antin

Tim, Just for info, that article is a condensed version of this article: https://www.er-emergency.com/wp-content/uploads/2011/12/F.-John-Fuchs-Blackstone-Net-Ultrasonics.pdf, and John Fuchs also wrote another article that goes into some deeper issues -...- Neil.Antin

Ultrasonic Cavitation & Cleaning Explained
Thank-you for the complement. It means a lot. It's nice to know that my efforts are appreciated. This article awad-reprint II (crest-ultrasonics.com) (which was written in 1998) is only 6-pages and maybe be easier to 'assimilate' and reflects what is written in my book (but not everything)...- Neil.Antin

Ultrasonic Cavitation & Cleaning Explained
Aziz, @tima has good points but let me provide some other info. The HG uses a very small tank (~400-ml) and the two transducers are mounted one on each side of the record and very close to the record. The Kirmuss is just an iSonic UT tank P4875-NH+MVR5 | iSonic® Ultrasonic Vinyl Record...- Neil.Antin

Ultrasonic Cavitation & Cleaning Explained
@abeidrov, I am going to give you an answer that comes right out of this free book Chapter XIV- Precision Aqueous Cleaning of Vinyl Records-3rd Edition - The Vinyl Press which discusses a cleaning process using two UT tanks, one for pre-clean and the other for final clean/rinse. Pre-Clean...- Neil.Antin

Tim: Latest official info says OK for cosmetics - cosmetics-restricted-subs - ECHA (europa.eu), and official information is scarce as to what industries it may actually be banned Regulatory - Propylene Glycol Sector Group (propylene-glycol.com). I would have to do some serious digging to find...- Neil.Antin

Since your question is not specific to the DG, I am going to respond at this thread that is more appropriate - Ultrasonic Cavitation & Cleaning Explained | What's Best Audio and Video Forum. The Best High End Audio Forum on the planet! (whatsbestforum.com).- Neil.Antin

Tim Where did you get the information that PG is banned in the EU? The EU was considering a pretty broad-based ban on many chemicals, but they backed-off and it is not banned, and their latest health hazard assessment continues not to classify it - Propane-1,2-diol 100.000.307 |...- Neil.Antin

The DG vs Kirmuss are two entirely different cleaning processes. Kirmuss is a manual-clean + UT process. The UT is 35-kHz. The 35-kHz gives big bubbles with high cavitation intensity. DG by itself is purely UT. The UT is 120-kHz (with lots of power). The 120kHz gives smaller bubbles, and...- Neil.Antin

Soundsmith Sussurro MkII re-evaluated
I also have a Sussurro Gold. A dealer made me an offer I could not refuse. I wrote the following review for the dealer that has been updated to address when I swapped in Graaf GM100 this last winter. What is the Sussurro MKII ES Gold? Piecing together info from various web-sites, it differs...- Neil.Antin

Ultrasonic Cavitation & Cleaning Explained
The 104W power draw would be about right considering that the power supply is not 100% efficient. The Elmasonic P60H which is a 6-L dual frequency machine 37/80-kHz PP_Elmasonic_P60H_EN.pdf (elma-ultrasonic.com) is rated 180W at 120VAC, but also a peak power of 720W. The unit has multiple...- Neil.Antin
