Stylus stuck in groove.

What do you mean by “gets stuck”? Does it skip back into the same groove over and over or does it literally get caught (that would be horrible)?

For tough gunk, I’ve found dabbing a microfiber cloth in ultrasonic cleaning fluid and wiping with a lot of pressure along the groove is the best way of getting rid of this gunk. I had this issue in the past when I was using a silicone roller to pick up dust from the records, which at some point started to deteriorate and leave silicone in the grooves. That’s the reason those types of cleaning rollers are now discontinued.

It skips back into the same groove

Thanks for the suggestion. I’ve ordered the cleaning solution.

@rvpiano I assumed you already had the solution since you have an ultrasonic cleaner. You can also just use distilled water if that is more handy. If you do decide to use solution, you can try adding a few drops on the area and letting it soak for a min or two before wiping.

I’ve also found it pays to be persistent. Keep wiping a while til you see the gunk gone (if it is visible). With a microfiber cloth, you don’t have to worry too much about scratching even with a good amount of pressure applied.
