    Just a video explanation of how I use to Q-ball to have zero grind retention in the Mazzer Mini E doserless grinder. Not for most I guess but if you're OCD like me on stale grind then might be something to consider if you have a doserless grinder.

        Well, I had the Mini-e apart yesterday to give it a good clean and it was chockers. That got me thinking you can never get every bit out, so personally I don't worry about it. I can't see a few grams of "stale" grind would make a difference in the taste. If you are using the grinder daily, how stale can it be? Maybe someone ought to do a taste test of coffees with and without bits of stale grind in it! Otherwise have a vacuum cleaner handy. :-)

          Did it once, collected the sweepings for a few days then pulled a shot using my collection, what was it like? let's just say I won't be repeating the experiment any time soon.

              hahaha, oh dear.......

              But that's 100% stale grinding ....... now go and pull a shot without cleaning out yesterday's grind out of the shute. You should be game to do this Yelta, this is mild compared to what you've done before!

                Hi franjae, one day's stale grind is one thing, however if you never sweep the chute the edges will continue to stack with stale grind. There will always be very stale grind left on the corner edges for as long as you don't sweep it out with a brush etc so potentially years old stale grind. You will be drinking minute amounts of these, doubt you'd notice unless you have a very sensitive pallet. I doubt you can ever clean out 100% stale grind unless you clean the chute as well as the blades but that's probably not all that good for the grinder so I just clean what I can reach and that is the chute.

                  The thing is I weigh each and every shot, into an empty hopper, grind, dose, then brush out the chute, run the grinder again briefly so that it spits out any loose grounds then brush out the dosing chamber.
                  When I've finished there are virtually no visible stray grounds left.
                  When I do give the Mazzer Mini a clean every 6 months or so I get approx 3 or 4 grams of caked on coffee out of the burr chamber (yep I've weighed that as well) as far as I'm concerned absolutely bugger all.

                    Hmmm, Must say I don't like the look of the anti static mesh one bit, it's a real obstruction.
                    Wonder why they use it on the E and not on the standard Mazzer Mini.
                    I would certainly be looking at a way of eliminating it.

                      Heaps to read about that all over the place, including the patent.

                        Crikey, that certainly adds a lot to the discussion.
                        If there's "heaps to read" I've yet to trip over it.
                        Perhaps a link or two, maybe even a clue.

                          Saoye - hats off to you, I'm somewhat less afflicted than you but if I find I haven't used the grinder more than a day, I use a simple skewer and poke around and it generally flicks out the stale fines. Then I'll run a bit through of the new beans, turf and then good to go

                          I dont use the skewer between shots but I will purge just before a shot if we're talking hours apart

                                Finally found that patent I mentioned:
