I hate to jump into the middle of a long set of posts, but I want to share that an ultrasonic cleaner does make good sense if you have LP's that do have embedded grit, and you dont have a cleaner that can excite, suspend and pull that material away. (in a manner more than a one to one ratio)
That greater than one to one ratio here is the key in my opinion.
I have an average collection, about 4K LP 90% used.
My styli are Jico, and old stock Shibata, so I’m not inclined to play anything until the LP's get cleaned.
I started by hand, with a paint pad
Then, by glue
Then built a RCM that leveraged a pair of paint pads, and a motor.
all way too slow.
So; I looked at what volume I needed to catch up; so I could enjoy my collection.
1. About 150 LP's an hour
2. As clean as they could be, to remove the wear factor from my Stylus
3. Portable, or at least moveable from room to room
4. self-contained (Self storing, all materials used in the process)
5. Suspends, and removes grit, and does not press it back into the item cleaned.
6. Has “Curb Appeal”
Ultrasonic was the answer
I’ve posted in a separate thread, but not to this detail
I had a unit manufactured for me, whilst overseas on a business trip. To my specifications, with a few BOM changes to drive reliability and to meet my needs.
High level specs:
A little over 22 liters of capacity in the main tank
5 liters in the filter and heat exchanger
Multiple drain points
Internal heaters
Transducers, designed for a range of frequencies; added to an existing model number the vendor produces, with other specifications I called out
Full adjustable for frequencies, power to the drivers, run time and temperature set point
A Pre-Civil war Walnut cabinet, fully stripped and restored
A fold out top that covers the cleaner when not in use, and allows double the area during use.
Top is waterproofed
The tank is countersunk into the top, so the lid fits, when the tops is folded
The electronics and relocated to an area in the cabinet, to allow easy access for service, and forced air cooling
The control panel is relocated for ease of use, to the false drawer
The controls are augmented with LP rotation drive controls, and status lamps
A re-circulation system pulls liquid from the tank, and routes it through a very large filter assembly, a forced air heat exchanger, and a pump; to return to the tank
The pump and filter are controlled separately from the Sonics
A drive section, that does not interfere with the lid when its closed.
Multiple "spindles" so I can clean, rinse, and load\unload in an efficient manner, and can be fully stored internally when not in use.
Stainless steel in all areas that touch liquid
Aluminum in areas that do not
and
a liberal application of fun, creativity and general common sense through out
Investment?
It was cheaper than I anticipated. It was not “Cheap”, but as we all know some of our LP’s are approaching the total investment of our cleaning solution.
How does it work?
Extremely well
I can set aside a single day and literally cut large swaths in my collection, and now begin to catch up.
so, I agree fully:
Ultrasonic cleaners work, and well
Not all are created equally, and education is the great equalizer
Building your own solution is possible
