I just recently discovered that my UV pet urine detecting light has a far more enjoyable use than looking for dried up puddles. When you shine it on a record, it shows EVERY piece of dust, most of which you cannot see in ordinary light. I thought my record cleaning process was good until I started using this. In an effort to remove every piece of dust that I was now seeing, I had to change my cleaning procedure. Now after the initial cleaning pass, I always do a R/O water rinse and Zerostat. The light that I am using is called "Simple Solution Spot Spotter HD". It can be picked up from Amazon for $15 with prime shipping. Trust me, you will be amazed when you try this.
