I am not a expert in any shape or form. I have been given very valuable guidance from the advisories on offer in the Link I have added.
The PACVR as its 2nd Edition was enough to encourage myself to make amends for any previous methods used to clean a LP Groove.
I took the producing a recommended solution quite seriously and I believe I have the mixture ratio's as per the recommended.
Today with the new adopted method I don't see the process as a Groove Cleaning Practice but more of Groove Purification Practice.
I make this statement without any reservations. I have had LP's cleaned in the past on what was considered a professional cleaning machine in the day, and have been regularly able to listen to a LP that has been through a Ultrasonic Cleaning process. I also set myself up to be able to clean with a UST.
I no longer see any of the other options as required, I am re-playing LP's that are being perceived as clean, to a standard where the perception of clean has not been witnessed in any past cleaning experiences.
I have brought a few extra disciplines to the process as a result of how I function in a professional manner. The simple to achieve idea of minimising cross contamination offers a extra satisfaction, as well as the simple to achieve pressurised rinses with a controlled Jet.
Most importantly I am unslanted on this subject, there is nothing to be gained for myself by endorsing the method. For me this is 'the method', and one that can be achieved that is not with any unwanted costs attached.
