Back To Static!
@dover,The normal use of anti-static brushes in industry as was addressed in the paper when I renewed this thread is stationary over a moving item. But industry uses conductive brushes that are grounded. But ’dissipating" static charge can take a ... 
Back To Static!
@dover, This is probably the best article for record static - Phonograph Reproduction 1978, James H. Kogen, Audio Magazine May 1978 Audio-1978-05.pdf (worldradiohistory.com) goes into some detail on static; what causes it and what does not – the n...

@oldaudiophile,1st, please do not start blending cleaning agents unless you know the composition, there is always uncertainty to the results.  So I recommend you do not add anything to the MoFi cleaner.If you read Chapter XIV starting XIV.8 to XIV...

@mijostyn,Industrial ionizers produce both positive + negative ions. If you reread the brush report you will see in Figure 4 were they address that both + and - ions can exist and page 11 - "When an ionizer is poorly maintained, the unit does not ...

@mijostyn,I think you have typo, the report says the brush alone reduced voltage to at best 3380V.  Regarding particles this is quite a statement from the report pageb16, "A Sealeze™ brush making minimal contact with a suitable substrate would be ...

@herman,Ultrasonic cleaning can be very effective against oils and greases, and the lower frequency units such as the Isonic/Kirmuss at 35-40 kHz are preferred.  BUT, they need some chemistry to both lower the surface tension of the fluid to bette... 
Back To Static!
@mijostyn,In my travels I can across this paper - Microsoft Word - SEALEZE_WHITE_PAPER_Final dam.doc.  My takeaway is that even under ideal application & use (i.e proper grounding) brushes are not that effective in removing static.  Recalling...

@oldaudiophile,The popularity of Tergitol 15-S-9 is that its a superior nonionic surfactant to Triton X100 (which I discuss Chapter XI) or Kodak Photoflo (which I discuss Chapter VIII). If you read the first part of Chapter X, there is no real mol...

@mijostyn, FYI - Here is a cheap source of Tergitol 15-S-9: Tergitol 15-S-3 and 15-S-9 Surfactant | TALAS (talasonline.com) $21.75/pint.Edit - In my PM, I meant to say Table I not Table II.

@mglik,The Keith Monks Discovery RCM is an awesome machine.  I have worked with some people over at the VPI forum with VPI vacuum RCMs and the Loricraft™ PRC-4 RCM with the following cleaning process (as quoting from the book Chapter XIII): XIII.4...

@oldaudiophile,1. If you read the book Chapter XIV.5.3, and you apply your tank volume of 6L with 3 records, the fastest you should spin is 1 rpm. If you clean just one record at a time, then 3 rpm is the fastest you should spin. The problem with ...

@willy-t,Tima uses the Elmasonic P120H (with pump & 0.2 micron absolute filter) and he has added a Elmasonic S120H for rinsing and recently switched  to Tergitol 15-S-9 ( Tergitol 15-S-3 and 15-S-9 Surfactant | TALAS (talasonline.com)) with g...

@terry9, ...you are too kind.@oldaudiophile, a few quotes from the book:Chapter XII.6.a - "...The paper Adhesion and Removal of Fine Particles on Surfaces, Aerosol Science and Technology, M. B. Ranade, 1987 (38) shows for aluminum oxide particles,...
