Is it ok to use Zero dust on A-90 ?

i'll add my 2 cents to Doug and Raul, the biggest issue is clean records to begin with. if they are mostly clean then you minimize the build up which increases the groove temperature and cakes the schmutz on the stylus.

i have 2 A90's and use the Zero Dust every few records very lightly and then the Magic Eraser every 10 Lps or so. but almost all my Lps are cleaned freshly on an Audio Desk RCM. the Audio Desk unit does not vacuum to dry so it does not add static; which reduces the tendencey for dirt to be attracted to the Lp surface.

if i play used records that i've not cleaned then i'm cleaning the stylus once a side.

i almost never use a liquid stylus cleaner as i'm concerned about it wicking into the coils and Cartridge body.

i'm sure there are multiple correct approaches, this is just mine.

Best you can do is to look for AT-637

Syntax, I've got one of them from years back. I got a bit hesitant to use it on my expensive carts.

No problems using it long term ?

looks like I should put a battery in it and use it again?

Don't worry, I use that one for > 10 years, best results.

Sounds good :-)

Dear Downunder: Syntax is right/spot on, that item is the one I used too for at least 15 years with superb results.

Regards and enjoy the music,
Raul.
