Mijostyn- those digital microscopes- at least the cheap ones- are a little tricky. The 'frame' of view with high magnification is very limited- obviously, and care must be taken to mount the microscope in a way that it is aimed properly and doesn't move or get jarred. I use a lab stand and lab type clamps- but I didn't go all spendy on a $400 US one-- they were under 50 dollars US. Maybe the expensive ones are better. You can definitely see a lot more.
For routine cleaning, i use various loupes- i did a little research on them, most of them are pretty bad, optically, and the claims of 20x-60x are kind of a joke. From what I gather, a jeweler's loupe should only be 10x and have triplet lenses-- I have several. One I use-- i'm getting old-- is a set of magnifying eyeglasses with illumination. It's only 3x, but sufficient for me to see the stylus and brush- i've been using a longer bristle than the pad type, as I mentioned.
I guess this is all obsessive but I think we agree that keeping that stylus clean as well as the records is pretty essential. One thing I found on my Airtight Supreme, which is now out for rebuild, is that a lot of stuff collected on the top of the cantilever. This, even though I'm pretty fanatical about record cleaning and stylus cleaning (the latter within reason). I also think there's a lot of stuff-- dust, human skin shed, whathaveyou-floating around in our rooms. I have a dedicated room, no pets allowed, no smoking, etc. and decent central air con and heat with good filters. There's still an endless amount of 'housecleaning' to do in that room, which just adds to the stuff that can collect on a record during handling and play.
