| Back To Static! @mijostyn,Are you sure the tips of the CF brush have not fractured? Pieces 5 microns in length and 7 microns wide would not be visible but could be audible. Come-come now, my manual cleaning procedure is not that bad, I can clean/dry/re-sleeve s... | |
| Back To Static! @mijostyn, None of these brushes will get deep down into the groove. Here is the approximate diameter of the three conductive bristle materials used for records: For reference the V-shaped groove has ‘nominal’ dimensions of 56 microns (0.0022... | |
| Record Cleaning Machines @oldaudiophile,This thread starting about page 18 to ~page 30 a pretty extensive review was performed by one person - Degritter Users | Steve Hoffman Music Forum. I started contributing about page 20 - handle pacvr.Paul Rigby did a pretty exten... | |
| Record Cleaning Machines @mijostyn,What I wrote is correct - Understanding Surfactants: A Guide - International Products Corporation (ipcol.com) | |
| 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... | |
| Record Cleaning Machines @daveyf ,If your read these two articles - Record -Groove Wear, J G. Woodward, HiFi Stereo Review Magazine, October 1968 HiFi-Stereo-Review-1968-10.pdf (worldradiohistory.com) and RCA Engineer Magazine, 1976, Issue02-03, Development of Compound ... | |
| Record Cleaning Machines 1. Water is for all intense purposes classified as nonionic; ASTM D1193, Standard Specification for Reagent Water, Type 4 achieved by distilled water (condensation of steam) has a resistivity >200K ohms and a total dissolved solids <2.5 ppm... | |
| Record Cleaning Machines @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... | |
| Back To Static! @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 ... | |
| Back To Static! @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 ... | |
| Record Cleaning Machines @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... | |
| Record Cleaning Machines @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... | |
| Record Cleaning Machines @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. |
