| Ultrasonic cleaning @scm, FWIW: If you compare the two SDSs between Trition X-100 TRITON™ X-100 Surfactant | Dow Inc. and Kodak Photoflo \14315sfp-1msdgenfilesarchivessds_usdefault�07903.pdf (lps.org), the CAS #’s are the same, so that adding Photoflo with Trition... | |
| Ultrasonic cleaning @whart, Bill as always thank-you for the kind words and the acknowledgement and of course your efforts as editor and publisher. One of the problems with record cleaning is that there are no clearly defined cleanliness criteria. I address this in... | |
| Ultrasonic cleaning @tuberculin, Are you using the Triton X100 at 0.13%? This would be about 6.8 times its critical micelle concertation (CMC) which is a pretty high concentration - but Paul Rushton specifies rinsing with a vacuum-RCM Are you spacing the records a... | |
| KLaudio or Degritter Mark II @oldaudiophile, Re-reading your post, I am not sure why you feel your CleanerVinyl pump/filter with the P60H would be virtually impossible. The pump/filter is (electrically) OFF during the first 10-min while the tank is in auto frequency change ... | |
| KLaudio or Degritter Mark II @oldaudiophile, I am not sure of your problem. Do not operate the pump/filter during the 1st 10-mins when then tank is switching between 37 & 80 kHz and then run the pump/filter for the next 10 min which is at fixed 80 khz. At continuous 80... | |
| KLaudio or Degritter Mark II @oldaudiophile, ".in a two-tank protocol employing my present 40kHz US machine and the Elma Sonic P60H, would using a 6L 180W, 132kHz cleaning power, 200W heating power, instead of the P60H achieve better results?" Recall that as the kHz incr... | |
| KLaudio or Degritter Mark II @cleeds, It takes little space... Do you have the latest LP200T version with the external pump/filter? manual_kd-cln-lp200t_d100eng.pdf (klaudio.com) | |
| KLaudio or Degritter Mark II @oldaudiophile, Someone recently asked me to assist them with cleaning lacquer/shellac records, so you pretty much got the same answer. Otherwise, all for a good cause. Take care & good luck, Neil | |
| KLaudio or Degritter Mark II @oldaudiophile, As I think I may have mentioned earlier, most of my core collection of LP records are already relatively clean. Should I avoid using the Knosti & Liquinox pre-clean step for those, altogether, or does that matter at all? I ... | |
| KLaudio or Degritter Mark II @oldaudiophile, Solution of distilled water + 0.01% or 0.015% Tergitol 15-S-9 + 1% Alconox Liquinox in the Knosti as a pre-cleaning step. Please do not get creative with the Tergitol and Liquinox - there is no need. Just use the Liquinox whic... | |
| KLaudio or Degritter Mark II @oldaudiophile, (1) I did, indeed, use 15ml of Tergitol. Using 0.9ml to achieve a 0.015% concentration seemed like so vanishingly little. I did not encounter any issues or problems with foaming. Also, I continue to struggle with the idea of... | |
| The "Very Best Record Cleaning Formulation" @wizzzard, "I know Engineers, and, you sir are no Engineer" You're attempt at using the infamous "Benson Quayle" debate line as an insult is pathetic. Just make sure you tell U.S. Navy and NAVSEA that they were wrong to award me the Engineer... | |
| The "Very Best Record Cleaning Formulation" @wizzzard, And now "Mr. W" relates "grade school guidelines" about drops and weights, never stopping to consider that I, Wizzzard, actually weighed out two drops of Tergitol 15-S-7 on his $5,600 Sartorius analytical balance. Not just once but fi... | |
| New Hobby Ultrasonic Record Cleaning "5-chloro-2-methyl-4-isothiazoline-3-one and 2-methyl-2H-isothiazol-3-one" The above is just an anti-microbial agent added for shelf-life. This free book - Precision Aqueous Cleaning of Vinyl Records-3rd Edition - The Vinyl Press goes into det... | |
| KLaudio or Degritter Mark II @oldaudiophile, First some observations on your current cleaning regime: The 15-ml of Tergitol 15-S-9 in a 6L bath = [(15-ml)/(6000-ml)]x100% = 0.25% which is 5-10X greater than what I recommend in the book - XIV.9.4. Did you mean 15-ml or 1... |
