I suspect I've answered my own question in the positive!
I’m currently using a newly serviced and updated Linn LP12 with a moving coil Dynavector Karat 17D3.
I’ve had my Okki Nokki RCM for three weeks. I’ve used L’Art du Son cleaning fluid, triple distilled water and all housed in amber glass bottles. I’ve varied the amounts used, the ‘action’ used to spread the fluid on the record (the ‘scrubbers’ and ‘spreaders’ debate). I’ve varied the amount of time I’ve left the fluid on the LP before vacuuming. I’ve used a ‘Milty Zero Antistat’ before the process. I’ve also tried using it after the process as well in case I’ve generated any static during the process. In every other way I’ve followed the instructions to the letter. I’ve also got two LPs on which I have tried several cleans. There seems little improvement between cleans two and three.
The symptoms are the snap, crackle and pop. Without a doubt on some records there has been an improvement. On others it seems negligible. Only on two LPs have I managed to get a near to silence finish (out of 15).
My initial observations are that the waste fluid is a very murky colour which would indicate the machine is cleaning. The supplied brush seems hopelessly inadequate for the task. It’s started to shed hairs and I do wonder how much of the bristle is actually getting into the groove. Some other threads/forums seem to suggest a velvet strip would be more appropriate. There are several very expensive brushes that might fit this bill.
I do understand that a badly damaged LP is irretrievable. However the LPs I’ve been cleaning do not look badly damaged and the RCM does make them look like new. Unfortunately it’s in the sonic department that it seems somehow lacking.
My specific questions are:
1. Am I using the best fluid? The web is awash with suggestions. Any recommendations based on use would be welcome.
2. Should I be a ‘spreader’ or a ‘scrubber’.......?
3. The brush needs replacing. I’m thinking of a homemade version using adhesive velvet strips if my local shop can supply it. Any recommended alternatives?
4. Am I using the most effective anti-static solution? There are several ‘wipe on’ products that get varying comments on the web. Again, any suggestions welcome.
5. Do I just need to keep repeating the process? (Am I being too impatient?!)
6. Any basic techniques I've missed on trawling the web that you could recommend?
My continuing vinyl journey has been an eventful, and largely positive one. I can hear with some LPs what is achievable. It would just be great if my substantial investment could be producing slightly more successful results. I also supect I need to be more careful in the vinyl I am choosing to buy - it's nearly all second hand - but even the clean looking stuff is having very mixed results. Thanks in advance for any suggestions you may have.
