Degritter Mark II
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

Ultrasonic Cavitation & Cleaning Explained
Why are you cleaning for 48-min? If the record is not cleaned in 20-min, additional time offers limited benefit and 30-min should be your upper max. However, based on the rpm, try to time for an even number of rotations so the record is equally cleaned. Example; at 0.63-rpm 15-revolutions is...- Neil.Antin

The purity of RO is dependent on the input water which varies widely such as U.S. EPA Freshwater Explorer (arcgis.com), select the Measured Conductivity NWIS tab and note that TDS is = 1/2 the indicated conductivity (uS/cm). If your locality has low TDS tap-water, the RO output can be very...- Neil.Antin

Ultrasonic Cavitation & Cleaning Explained
Easy enough to check. Place a couple drops of the distilled water you use with no chemical and a couple drops of the AIVS diluted/prepare solution on a clean hard smooth surface - like glass and allow them to evaporate. Is there any difference between the diluted in-use AIVS with the pure...- Neil.Antin

Long story short, either is fine for record cleaning. If you are in the US, distilled water is readily available in your local grocery store. If you are in the EU/UK demineralized water is more readily available. There are subtle differences between them, the pH of distilled water tends to...- Neil.Antin

Ultrasonic Cavitation & Cleaning Explained
The photos show that the aluminum foil is dimpled, but not much more. After 2-min, a powerful tank would have probably produced more holes, acknowledging the 60-kHz frequency and also knowing that as the kHz increases, you need more power - see the very 1st post in this thread. However, I...- Neil.Antin

Ultrasonic Cavitation & Cleaning Explained
If after 48-min, the tank was just barely warm, then either it's a very low powered tank or the UT transducers are not all working or barely working. Try doing an aluminum foil test - to verify that you are getting cavitation. However, just know that the aluminum foil only shows that there is...- Neil.Antin

Ultrasonic Cavitation & Cleaning Explained
@Packgrog , I've been using a variation of your cleaning solution recipes, dumbed down for me by another chemist in the community. I've been using a 10ml Liquinox per Liter distilled water dilution for my pre-cleaner, and 25ml/L Ilfotol for main cleaner, in rinsed out old AIVS dispenser...- Neil.Antin

Tony, How often do you top-off the IPA? How many days before you have to add IPA? Take care, Neil- Neil.Antin

Ultrasonic Cavitation & Cleaning Explained
Tony, Long story short, you want to rinse after the Liquinox or you will carry it over to your ultrasonic tank and it will increase the TDS measurement and lead to foaming. Take care, Neil PS/Read the book version 3.1, XIII.5 Importance of Rinsing.- Neil.Antin

How long will a Tergitol mix "hold" in a UCM tank?
Tony, Tergitol 15-S-9 is non-volatile, so it's not going to evaporate from the water, in fact, if the water evaporates, the Tergitol 15-S-9 concentration increases. So long as the bath is clear, and has no objectionable odor, its fine. However, if the bath 'had' IPA, that could be a...- Neil.Antin
