| Thumbs up for ultrasonic record cleaning I just changed the filter from 1um to 0.5um. After some 20 Lp's first pre-cleaned with vac the old filter did have some particles left on it - like a very fine grayish sand plus a bit of yellow coloration. So the US does extract something vac did ... | |
| Thumbs up for ultrasonic record cleaning @fleschler Have you tried vac re-cleaning/rinsing those Lp's with rolled off highs? | |
| Thumbs up for ultrasonic record cleaning @gbanderhoos @terry9 Guys, I don't think that was really necessary. The multitude of approaches and opinions is what makes the progress possible. Quite surprisingly, US cleaning is still a pretty fresh subject even for scientists - I've googled ou... | |
| Thumbs up for ultrasonic record cleaning BTW, those using Tergitol - what are your rinsing procedures? After my PhotoFlo disaster I'm quite obsessed with rinsing: I first use high purity water. Distribute it with a rinse brush, rotate 3x with the brush on in one direction then 3x in the... | |
| Thumbs up for ultrasonic record cleaning On Kirmuss - he seems to go pretty much against all the usual US considerations. Perhaps he is right, I’m not judging. But its seems that in semiconductor industry, where they are most preoccupied with damage, they go not for 80kHz but for 800kHz ... | |
| Thumbs up for ultrasonic record cleaning @terry9 1) Rotation - I know! See my posts.2) Rinse - it’s 2 stage :) see above3) I’m a bit afraid of passing 35C4) Spacing - I use 6L 150W cleaner with 3records max but at 70% power. The central record is 37mm (the 40Khz wavelength) to both side... | |
| Thumbs up for ultrasonic record cleaning @whart Nope, I'm in EU, but can order that, thanks. | |
| Thumbs up for ultrasonic record cleaning @whart Interesting re the brushes. I've been using brushes (Osage for cleaning, Okki Nokki for the rinse) thinking they create more resistance, which is what I want (I like working harder through the vinyl surface). Never tried pads but will defin... | |
| Thumbs up for ultrasonic record cleaning I must say I was perhaps a bit too harsh on US. Most of my experience was based on 10%IPA +0.1% PhotoFlo for 10min at 70% power, 33C, 3rmp, and then a US rinse with DI water to get rid of the crappy PhotoFlo "plastic"sound. Now I’ve cleaned about ... | |
| Thumbs up for ultrasonic record cleaning @terry9 Thank you, you shouldn't have spent so much time on that - was just asking out of curiosity. Sorry for causing trouble. | |
| Thumbs up for ultrasonic record cleaning @terry9 Could you pls link to the diyaudio graph? Thanks | |
| Thumbs up for ultrasonic record cleaning @whart That's what I thought - KL discourages use of any add-ons no? Honestly, I'm sticking with alcohol just by some inertia. I like it for its grease dissolving properties. Also as far as I understand, it actually makes the 40kHz cavitation gent... | |
| Thumbs up for ultrasonic record cleaning @whart Thank you very much for your informative input! This is similar to the process I'm currently using, but I do not rinse after the vac pre-wash since I US clean with the same solution as I vac (5% IPA + 0.05% Tergitol).What do you use for you... | |
| Thumbs up for ultrasonic record cleaning @dgarretson Very interesting observation re 38 vs 80kHz! Have you made some systematic research on it? There is quite some discussion re frequency going on. You input would be very valuable. At the moment I'm afraid to go past 35C and 15mins. If I... | |
| Thumbs up for ultrasonic record cleaning As a follow up, directions I'm considering:*80kHz tank since I use it as the 2nd stage and 80kHz process is more penetrating but gentler*slower motor; anyone knows of a cheap 1/3rpm or so motors in EU? 230V synchro would be the best*submicron filt... |
