Background: I have cleaned ~4500 LPs using the following process:
- Tap rinse
- Spin Clean w soap - 6 revolutions, each side
- Ultrasonic clean w soap at 2 different frequencies (Elmasonic P, from Germany, 37/80 kHz), the 80kHz produces less heat,- which is a key issue for LPS (most units do not offer this feature).
- Tap rinse / drip dry
- Spin Clean w D.I - 6 revolutions, each side
- Drip dry in a rack / wipe with Spin Clean drying cloths
- Store in new sleeves...
First, I know this process is/was excessive. I previous worked in an analytical chemistry lab, so I was accustomed to excessively clean processes/equipment... I cleaned a few LPs each evening, and many during the weekends.
I have finished this deep cleaning. Now I simply dust each side with a Disc Washer brush before playback.
I recommend you try a few steps to see what satisfies you, your needs and your time-budget.
Second, please know that cheap equipment is CHEAP ONLY ONCE. After that, you pay every time you use/replace it... (a lesson that my favorite boss taught me years ago). I will never buy a Kirmuss gear - period. There are very few companies that I refuse to consider. I have no confidence in their products - YMMV.
Best of luck with your adventure and feel free to message me if you want to 'pick my brains' for more details...
