I've used these types:

The AT637 vibrator - which is good for fluff and dust but no good for vinyl deposits/grease.

AT607 fluid which is great for vinyl deposits/grease but I'm also a bit wary of using on expensive cartridges though I have done this and never knowingly had problems.

Zerodust - a semi-solid sticky gel that the stylus sinks into. It deals with all types of dirt but probably less effectively than the above methods.

Linn sandpaper. This never seemed right so I stopped years ago.
