    Legendary, i'll do that tomorrow, just wanna say thanks heaps for guiding me through cleaning it. Truly was going to use the dirty grinder 'as is' for fear of damaging it haha :/ Would've been an unpleasant experience...
    Thanks again!

    Hmm yes i'll be sure to try that out next time.

    Also I found out that blu tack works wonders, I was able to get it into every single nook and cranny. It took about >95% of the grounds out and whats leftover with the oils I used your suggestion with slightly damp towel and wiping it gently. I didn't have any cafetto but I hope 2 drops of dishwashing liquid was good enough. I think the blu tack method was the safest as there was no contact with water at all, and the machine exposed to only very brief contact of water which was quickly wiped out and dried with the towel, sounds pretty good to me. Anyways really happy with the outcome, super dooper clean now and the smell is fading as I let it breathe in the air. Check it out!

    That's why I suggested the manufacture of a simple Bearing Puller that would place the force on top of the Bolt Head in the rotor shaft. Plenty strong enough then for repeated use, say annually, to give the innards a good cleanup.

    Best to soak all the (non aluminium) grubby parts in a strong solution of Cafetto Espresso Clean, using hot water. Would recommend about a teaspoon of the stuff dissolved in a jug or small bucket of hot water, then dunk all the bits to soak for an hour or two. May take more than one go at this to achieve complete cleanliness but it will do a great job...

    With all of the aluminium parts, you could try the IPA and see how you go. Don't know if it will do a lot but will probably require a bit of elbow grease. Another option would be to soak a folded up paper towel in the above strong-ish solution of Cafetto, repeatedly wipe over the old coffee oils and then thoroughly rinse off immediately afterwards. If you leave the Cafetto solution on for a while, it will start to corrode and mar the aluminium surface. Someone else may have a better (non-corrosive) solution for doing this but it is what I have done with old, uncared for grinders in the past, with no detrimental effects other than to achieve a bright, clean surface.

    When you're finished, just thoroughly dry off all the parts (perhaps in a warm oven), reassemble and you're good to go...

    MGT, Thanks so much for that tip! haha, got it off finally so happy about it. The screws left some small dents on the bottom of the chamber (because its a quite thin piece of metal underneath) from the force needed to pull them out :/ But I think it should be fine as theres also protruding screws on the metal anyways, but not something i'd want to do often though.

    Also, what do you guys recommend cleaning the chamber with? Isopropyl wipes is ok? I'm gonna wash the carriers and burrs in dish soap also if that's safe to do?

    Thanks for the info MGT & Dimal, before seeing this i was still prying it off with a flat head screwdriver wrapped in paper from the exit chute. After 30 mins trying, I was concerned i'd bend the screwdriver first before getting it anywhere near to budge even in the slightest. Will try your method tomorrow MGT, any idea what size screws they are? i'd have to head to bunnings for that.

    I was probably right that the carrier had never been once cleaned :/

    Handy to know M'GT...

    Didn't realise that the threaded holes run straight through.
    You could also make a very simple Bearing Puller to do this given the above.

    I wouldn't do that, as it poses a slight risk of bending the carrier so the burrs end up out of parallel.
    My method if the carrier won't pull off easily is to get 3 long screws with the same thread as the burr mounting screws, thread them down into the screw holes into the carrier until they hit the bottom of the chamber, then tighten them each 1/2 turn, then each 1/2 turn again and so on (to spread the forces evenly) and once you have some decent tension on the carrier, place a block of wood on the centre of the carrier and give it a thump with a hammer to jar it loose. If no joy, repeat by tightening all the screws a bit more (keeping it even) and trying again. Has never failed me, and have never ended up with bent parts except where they were already bent, and were coming off for replacement.

    It's probably stuck together with coffee oils that have oxidised and turned into a kind of varnish.
    Try some gentle taps using a piece of 8-10mm dowel, vertically around the circumference of the Slinger.
    Hopefully this will fracture any varnish that's causing the problem and then allow you to gently lever the Slinger off as per the video...
