Excellent! It really cleans the dirt, quite easy to use (takes a couple of days to do it without making a mess). It's amazing how well it works on static electricity! After drying, the discs are completely free of static! The liquid is reusable, so it produces quite a few discs.

ESSENTIAL for vinyl lovers, especially for those who buy second-hand records. I noticed a big difference in records that had been played with liquid in the past, or had used anti-static spray and left residue. Unfortunately, it can't do anything for scratches, but it does an excellent job with everything else (residue, dust, static).
Note: The included liquid is enough for about 100 records, then it needs to be replaced (sold separately)
