How often to you clean vinyl and the needle?

Clean; when it comes to my home before I play.

Carbon brush before every play.

Needle; after Inspection or about 20 hrs of play.

Vinyl once, stylus as needed.

Record with brush before every play.

Stylus as needed = rarely.

I clean an LP on my Degritter when it first acquire it. If it's brand new I just do a DW cycle. If I bought it used I do a two-cycle clean, once with detergent followed by a DW rinse. After that, I clean the record as needed.

With my cartridges, I clean the stylus tip with the Lyra SPT and provided soft brush before each listening session. Then I use one of those round carbon stylus brushes after each side or at least each record (two sides). After about every 50 hours of use I clean my stylus with the Flux HiFi ultrasonic cleaner, but for no longer than 10-15 secs.
