It's main value is that it is so much easier to do than disassembling the top of the grinder, unscrewing and rethreading the top burr and (worst of all) dealing with all the grinds that fall out onto the counter.
Good point. That's exactly why I was asking. The rethreading always frustrates me, the grounds everywhere and the stains all over the rags used for clean-up???. Also, my wife is bothered anytime I take my equipment apart (I don't think see trusts that it will get back together again). I'm just looking for something easy for between the big cleanings. I still plan on taking it apart, maybe on schedule with descaling my machine, but life has got to be a little easier.
Don't run disgusting, oily, over roasted beans through your grinder. If you don't, then every time you use your grinder the coffee you are grinding will help to clean the grinder burrs of older coffee.
Also a good point. I did take it apart yesterday and found some caking, but nothing like stains or oily build-up.
As someone who has to live gluten-free the fact that Puly Grind states that it is GF caught my eye. Just wondered if it was worth the price. A lot of GF products are just a rip-off.
Thanks for the great responses
