Record Cleaning - part 5: Halloween Horror The Gruesome Truth! Ultrasonic Cavitation killed my vinyl

Following up on my previous videos (linked below) I wanted to establish whether a sonic trend or trait of the HumminGuru's 40kHz ultrasonic cleaning was indicative of possible damage being caused. Plus, the famous 'aluminium foil test' certainly filled me with concern. So, in this video I push the HumminGuru cavitation to the limit, attempting to verify that the reasons for NOT using 40kHz are valid. Please watch the video to find out the results.

In addition I revisit the subject of cleaning chemicals, in particular with regard ultrasonic cleaning: are they necessary, do they help, and how important is it to rinse them off?

Finally, I try Tergikleen, a variant of Tergitol, and investigate it's cleaning ability and discuss some real concerns.

If you've not already seen them, do please take a look at the previous videos in this series:
