I clean all my new records on my Degritter before I ever play them. I also have a Keith Monks DiscOveryOne that I use before each play.
I had a HumminGuru and it worked well, but I just yearned for the Degritter...
I also have a Record Doctor X that I use when I hand clean used records.
How much noise will I accept on a new record. None!
I have also noticed a lot of new releases are arriving warped. I use my Orb DF-01iA on those. If they flatten properly and sound fine, I keep them.
