Ultrasonic record cleaners

@drbond,

The 'solvent' in Kodak Photo-Flo as I addressed is propylene glycol - and it is not harmful to a record; and it is non-toxic in many cosmetic products.  

So, with my new, updated ultrasonic LP cleaning process, I do notice a significant improvement in sound quality. The updated process has made my slightly noisy LP’s (static, pops, etc) almost silent, with only an occasional static pop noted. The LP’s that I formerly couldn’t even listen to because of the surface noise (mostly static-type noise) are now very listenable; although there is still noticeable surface noise, it is greatly diminished (I would roughly estimate a 75% drop in surface noise). Overall, it’s quite an improvement, and I’m beginning to wonder if longer, and a few more cleaning cycles may even clean up those troublesome LP’s that were formerly unlistenable. . .

Thanks to everyone for their input, and thanks to @antinn for sharing his knowledge. I don’t suppose that there’s a hard copy of your book available for purchase? (I generally don’t like clicking on links to "download" items because of virus and malware risks.)

@drbond,

Good to hear of the improvements.

The book is only available free by download, Precision Aqueous Cleaning of Vinyl Records-3rd Edition - The Vinyl Press. Bill Hart @whart runs a tight ship as they say, and I can only guess that the book (pdf) has been downloaded many, many times with no one ever indicating any malware or virus. The document was scanned for viruses and malware before being posted and the (my) computer that was used to write the document has a very high cyber security posture and the book is password protected from making any changes.

If you download the book, before opening, with MSWindows you can right-click and there will be an option to scan the document for viruses/malware.

@drbond - loved the bread commercial if you remember it.

I cannot control the web, but I use Cloudflare and have a really good IT guy here in the States. If you have access to a robust computer/printer system (work?), you might ask them to print for you. I’m sure there are other alternatives- get a commercial print shop to do it for you, at a fee. Interesting issue, never had it raised before, but I get where you are coming from.

Oh, PS: I guess I should mention that in more than a year of different versions being available on TheVinylPress, I have not once received any message that there was a problem, virus, etc. with respect to the download. But I don't want to twist your arm here. 

I'm careful what I download too. Vinyl Press has caused no (0) problems for me. @antinn How do you clean Tigercloth without compromising it's properties? Thanks!
