@antinn Sorry I offended you. I'm sure because you have written books, manuals and patents you're well known as an expert submarine tube cleaner. Now it is good that somebody has written something definitive, but not conclusive. That information was never in one place before.
I was merely stating, as I have before, my system works. I tried your Tergitol, it didn't work as well. That's why they added the second Tergitol, to make it the same as Triton X. As a matter of fact I have tried all of the chemicals that you recommend in my US tank and not one gave me the same results I get currently. I also used them manually before a vacuum, still not as good. And, I have zero damage and sonic loss.
The problem is removing tobacco smoke residue from the vinyl after it has set for 25-50+ years. My US system doesn't always get it the first time. I've found using the enzyme that comes with the Walker 4-step system will do a decent job if applied properly. I doubt yours does better.
You seem to be very sensitive about criticism.The fact is there are many ways, as you state, to clean records. Just look on YouTube, there are some crazy people out there..Everyone talks about your stuff as the be all end all for record cleaning. It's just a long tome with a lot of chemistry, that few people understand. I'm glad people are happy with it. I'm glad you're happy with it.
Happy Holidays
