Hi guys,
I am writing to add my input on record cleaning, having had many years of experience.
I am using both an ultrasonic cleaner and a Loricraft record washer in what I believe is a very effective manner.
The methods are different, but the results are similar to what Peter has described:
“I have both a Loricraft PRC 4 Delux and a KLAudio. I will not be selling the Lori. I find that I need both for best results. The Lori with 4-step AIVS fluids gets mold release compound out and I like the super pure water rinse. So right now I am first using 2 X 5min clean and one 4 min dry on the KLAudio and if I care and want to spend the time for even better results, I use the Loricraft with 4-step solutions and double pure water rinse. Super quiet vinyl surfaces and I can hear deep into the music for very subtle details and hall ambiance if it is on the recording. The double cleaning removes a slight greyish veil even on new LPs, and is wonders for used, second hand LPs. The ultrasonic cleaner might be slightly better at removing hard crud/grit that causes clicks and pops as long as it is not actual groove damage, but the Loricraft also brings something to the results. The bottom line is that the surface noise is reduced and the backgrounds are blacker allowing one to hear more of what is on the LP. YMMV.”
I had a VPI 17F for years but never really liked it. I spent too much time cleaning the brushes to keep them from transferring from one record to the next. The Loricraft was a big step forward. My records sounded cleaner/better and no residue transfer.
I bought an Elmasonic P60H and really got clean! But I kept using the Loricraft after the ultrasonic because I liked the improvement from L’Art du Son cleaning fluid.
The L’Art instructions are to mix the bottle with one gallon of distilled water. I mix it with FIVE GALLONS of distilled water. With any stronger mix I can hear that the sound is veiled. With my dilution, the benefits of using L’Art du Son as a final cleaner and surface treatment are optimized. Music comes alive with this additional step. Records have increased soundstage depth and sense of musical ease.
I clean three records at a time in the ultrasonic. A mixture of distilled water and alcohol (actually, Everclear – grain alcohol). The alcohol can give records a slightly thinner/brighter/dryer sound, but I don’t care because I’m going to L’Art them afterwards. 30 minutes revolving in the ultrasonic is good for most records that are new, or near mint, or cleaned before.
After the ultrasonic, I wipe the records down with a quilted microfiber cloth.
Then I do the Loricraft while the next batch of 3 records cooks in the ultrasonic. It usually takes about two hours to do 6 records. If I do this for two hours a day for 3 years, I’ll be close to being finished with my current collection. Glad I’m retired!
Some words about my DIY Ultrasonic. I got many of my ideas from this thread:
https://www.diyaudio.com/forums/analogue-source/218276-version-ultrasonic-record-cleaner.html
My ultrasonic cleaner is an Elmasonic P60H with both 37 and 80kHz options. I normally use 80kHz. Three records rotate at 6 RPH (3 revolutions in 30 minutes). I warm up the fluid to about 35 degrees C with the built-in heater. After 30 minutes of running, but without the heater, the temperature is up to about 45 degrees C. I then cool the fluid back to 35 degrees with a circulating pump and radiator (from a water-cooled computer). The fluid passes thru the same 1 micron filter that was described earlier by tima.

I hope that this is helpful to some of you.
