I've been contemplating getting a Humminguru as I've been intrigued about ultrasonic cleaning ever since I got the VPI. I thought about doing the whole DIY thing many times. Prior to the VPI, I just cleaned records by hand using the sink and
dent puller method - which I still do for those really dirty used records - with a final wash/dry on the VPI.
Not sure I can convince the wife I need another thing to clean records, though....and I have no issues with using the VPI.
For those that have already have a Record Cleaning Machine, does having a Ultrasonic machine keep you from using the RCM, or do you still use it along with the Ultrasonic? Do you use one or the other for releases that need a specific type of cleaning?
In my case, I don't clean new records unless they need it. If they are visibly dirty or if they have some sonic issue that sounds like a cleaning would fix.
