I have used #9, in conjunction with a LAST stylus brush for quite some time and with satisfaction. I use two bottles, one for cleaning by putting a few drops on the LAST brush and one for "rinsing". I've even used it on quite a few styli of yore that I have been trying here and there. Before and after cleaning with the #9, I've inspected them under an old microscope I "acquired" when they built a new Chem-Bot building while I was in college. They all LOOKED pretty cruddy before, but spotless after. So, I guess it works as far as whatever can be "seen" is concerned.
I bought one of the Mr. Clean eraser that Doug suggests and tried that, too. I must say that I may not be steady enough of hand, keen of eyesight, or bold in confidence to use it on styli in the manner suggested. Reminds me of the old Linn “matchbook striker-type” paper that used to be around. Not sure I am that “stable” to do that these days! I like much better the idea of up/down as recently initiated. I will try that method with a #9 flush.
