Looking for advise and recommendations on a nice record cleaner.

(a) have an audiologist clean out your ear wax (and do a frequency sweep at the same time, so you get a baseline of how your ears are hearing)

(b) ban your friend from your music room; he/she wasn't listening to the music, anyway!

Degritter - really well designed and made.

I’ve been using the AudioDesk Ultrasonic cleaner for over 10 years having owned the original model and now the Pro upgrade. Cleaned 2,000+ records. Whilst expensive, it’s proven to be the best investment in upgrading the sound quality of my system. Even brand new records need to be cleaned.

With a MT-10, and assuming you also have a high value cartridge, you should not be playing vinyl that is not cleaned well.  Period.

Utrasonic is the standard in my opinion. Several have been mentioned here.  I have used the Audio Desk Systeme for many years and it improves all records, new and old.  Amazed at how good some LPs from my high school years sound.

Loricraft 4. Has a strong vacuum pump although I've heard not quite as strong as it was before SME bought out Loricraft. Don't know if true. 

But it uses a new piece of string so it's always 100% clean.
