So I'm starting to notice something. Whenever I polish a blade using Flitz, Metal-Glo, or Mother's Mag, it feels like the blade edge dulls a little bit. Does the circular rubbing combined with the polishing paste make blades duller, or is it just me? Because they don't "feel" as sharp after a few polishes as when I first got them, and I've only cut milk jugs with them on occasion.

Its an abrasive, so i could see it wearing down the edge after a few goes.

It will dull blades in the same way that a whetstone can dull blades. It can also make it sharper (again, just like a whetstone). It's an abrasive, and it can make the edge sharper or blunter. If you have a gob of polish in a tissue, and rub that along the edge, line wrapped over the edge, it will blunten it. If you keep to the edge geometry (e.g., like stropping with something with your polish on in), it can sharpen it.

It’s abrasive and will dull the cutting edge. I’ve done it. I don’t use polishes often as I don’t like the finish but when I do I’ve learned not polish with the towel wrapped around my finger(s) and to be careful and stay away from the cutting edge. It’s best to use the polish on a cloth with hard backing in order to avoid it from overlapping on the edge. It's rare these days for me to use a polish preferring sandpaper.

OMG...how did I not see this? Ok, so edge polishing is a thing. I use a 'Wicked Edge' system to sharpen, and polish edges. I use a 10.00 microscope to check scratch patterns etc. I've stropped with Simi Chrome (similar to flitz) and my best guess is its about 1000 grit. So polish the blade, but strop to polish the edge.
