Temperature of water for ultrasonic RCM

@fuzztone - why 30c? curious. Thanks

@kgturner  - was unaware of that. Thank you. Is the heat generated at the record surface by the water hitting it? Any idea of temp? thx

I've used up to 45c but now go around 35c. I believe that after the surface is clean, it's more important to use a surfactant to release imbedded particles than having heat a main factor

Ultrasonic activity can raise the water temperature by about 10-15° C. I guess it would just depend on how long you run the ultrasonic transducers and how large your ultrasonic tank is.

I used to have a DIY 6L ultrasonic cleaner and without using the tank heater, I would get about a 5-6° C rise after 10 minutes.

I now use a Degritter (much smaller tank) and it will pause for cool down if I run it on Heavy for more than 1 LP. Luckily, I don’t do marathon cleaning sessions otherwise I could see how that could get annoying.

I start at 30 C and go up to about 42 C.

I`ve cleaned as high as 45 C without issues

I’m using an Isonic without heater, and I’m trying to figure out a way to introduce a little heat to the process.  I used it 5 hours yesterday, and the water was as cold when I finished as when I started.  When I dropped down to 4 records per cycle, with @2.5 inches between each disc, I noticed a big difference in results.  It was good with 10 records, but now I can visualize the water acting on the surface of the record.  Results sound even better.  Seems like slightly warmer water would be helpful?  Something short of buying a new unit.  Any ideas?
