Wet Cleaning the Stylus

Dhcod- I also use an EMT, great cartridges BTW. I discontinued use of the Onzow, based on recommendation! So now 90% of the time I use a dry brush.
The other 10% of the time is either ME or wet brush. The latter with just one drop of Disc Doctor. When Cleaning my Dynavector, I use ME more often, and and still dry/wet brush. So yes, as Doug mentioned, do check with specific manufacturer.

Personally I do wet stylus cleaning only in case if gets contaminated so can't clean it dry. Otherwise I'm too lazy to open the bottle, drop on the brush and never had any kind of thought about it being not a good idea after all.

Had this product been meant for the audiophile industry, it would cost ten times more than what it actually does.

Shhh!

Consider what is going on at the stylus and cantilever level. The crud build up is basically just dirt, bits of vinyl (hopefully not much vinyl) and some chemical residue. What is needed to clean it is just some mild detergent solution and a light physical scrub.

I've used a stylus cleaner kit I was given with a Lyra Clavis da Capo and also the Disc Doctor stylus cleaning kit brush and liquid. Both clean the stylus and cantilever quite adequately.

IMO, it is necessary to use a wet brush to actually loosen and remove the build-up on the cantilever and stylus. A Magic Eraser might work OK for the stylus, but there is a minimal benefit for the cantilever. In my opinion.

Wet clean your stylus only when truly necessary. Wet clean your LPs on a vacuum RCM and you will hardly ever need to clean your stylus. Sounds better and it will save you having the tip falling off as the glue bond weakens with repeated cleaning.
