    Re: Grinder Cleaner.

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I used some (40g) a month or so ago, in our Gaggia MDF.

    Makes a lot of noise and sends white powder flying all over the place.
    Generally speaking, a lot of fun to watch :)

    More to the point, it seems to have done a good job of cleaning the grinder.
    Will use it again.

    And one day will get around to pulling the grinder apart and verifying the above ...

    Re: Grinder Cleaner.

    Ive found that using stuff like this is mostly not necessary with the couple of grinders that I have owned.

    Have found it to be far easier and a lot less messy to just remove the hopper and the top burr carrier every now and then, and then use a vacuum cleaner to suck all the grinds out from the top. If there are any stubborn grounds, just loosen em up with a toothpick or similar and then vacuum again. Only takes about 10 minutes all told and everything is spotless ;).

    If you have a doserless machine like the Rock, e.g. then its only another couple of minutes to remove the spout and vacuum the discharge chute area. Very quick and very little effort.

    Cheers,
    Mal.

    Re: Grinder Cleaner.

    Someone once suggested using rice through the grinder to clean it.

    However not realising that when speaking to our well educated cafe owners and operators out there we have to use the "Lowest Common Denominator" principle - it should have been emphasized that the rice should be uncooked.

    DONT DO IT...

    The suggesttion was to use par-cooked 2-minute style rice, NOT uncooked rice. Nevertheless, the only thing that goes in my grinders is coffee. I can see it now, damaged grinder with rice bits still resident goes back for warranty repair. Miffed owner unhappy that warranty is refused on grinder not used for the purpose designed. I would definitely reject a claim if I found any evidence whatsoever of rice.

    Re: Grinder Cleaner.

    I remember that thread as well, and the final upshot seemed to be: Dont put rice of any description through your grinder. Cooked, raw or "2-minute", none of them did the job and mostly they created a nasty mess.

    Re: Grinder Cleaner.

    The rice thread never made sense to me anyway.
    I cant conceive how rice could clean a grinder.
    Its not about to soak up anything and if it only replaces left over coffee bits with left over rice bits, whats the point.

    As Mal said, its pretty easy to clean with a vacuum cleaner.
    I bought one of those mini hose and attachment kits and it gets into the nooks and crannies pretty well as far as I can tell, because I have yet to take the grinder apart.

    Re: Grinder Cleaner.

    Someone put rice that they cooked for two minutes through didnt they?

    Vacuums are the best, coupled with a small stiff brush to get the caked on stuff out.

    In the wake of the Asian financial crisis of 1997-98, rice producers in the Philippines have weathered extremely tough times. As a result, they have explored diverse ways of finding new markets for their produce. An increasingly common way to do this is by using rice by-products to make products such as rice paper, rice coffee and rice wine.

    I personally wouldnt put anything but coffee beans through my grinder. The trusty paint brush and vacuum do the job for me.

    We use kitty litter made from rice husks.

    I use the vacuum cleaner method.

    Not sure about the residue left over from these things.

    Re: Grinder Cleaner.

    I think the original use of dry rice might have come from a reference on Alan Frews website as a means to clean a caked up grinder. But as has already been said, youre only replacing one compound with another and then having to flush the left-over rice out with more coffee..... makes no real sense and I dont know why Alan would recommend this as an option?

    Re: Grinder Cleaner.

    I think you answered your own question. Used to clean burrs if you dont want to take them off that have really old caked on coffee that is rock hard....eg a cafe grinder bought for home use that hasnt been treated well.

    That said...when I cleaned the burrs from a cafe grinder a friend had....I needed a screwdriver to get that crap off.

    Re: Grinder Cleaner.

    But would the rice actually shift such aged and difficult deposits as youve described? How difficult is it to remove the hopper from Mazzers et al for a simple clean out with a stiff bristle brush and a vacuum? Cant be that hard surely :-?

    Re: Grinder Cleaner.

    Hi guys,

    Coming late to the party ...

    The Americans often talk about using "minute rice" to clean out their grinders. I think that this is where people got the idea to boil their rice for a minute or two, then running it through their grinders, which creates a horrible mess. In fact, by "minute rice" they mean the product manufactured by Kraft.

    I have a bunch of urnex grindz at home and it works very well indeed for cleaning flat burr grinders. It is more difficult to flush out of conical burr grinders. However, I havent really noticed any difference in the cup after cleaning my grinder. My theory is that anything gummed up inside will either be purged out or will not move. I guess that this is yet another myth that Id like to actually test under controlled circumstances if I had the time.

    Cheers,

    Luca

    I agree with Luca, havent tasted any difference yet regarding so called cleaning of the grinder.

    Doesnt seem to make any difference to me.

    Re: Grinder Cleaner.

    I have a question .

    I have just bought a Rossi RR45 that was last used in a cafe 6 years ago. It is clogged with oils - in the throat there are whole beans embedded in a black stinking tar like substance which I can only assume is the accumulation of coffee oils gathered from years of neglect. This gunk is also resident around the burr carrier and exit channel to the doser and in the doser itself.

    I have scraped out the majority of it but I am unable to get the rest.

    I have tried metho (not alchohol soluble it seems), washing up detergent in both boiling hot as well as cold water but with no success.

    I have not tried a petroleum based solvent such as petrol / kero / turps etc as I think any residue would probably taint the beans worse than the crap already in the grinder.

    Is there a cleaning product suitable for the job or do I need a specialised commercial product?

    I think it is beyond the grinder cleaning tablets as all the parts will need a good soaking to get rid of this stuff.

    All suggestions welcome.

    Thanks

    Jeff

    Re: Grinder Cleaner.

    When you bought this grinder, was it

    a) black
    b) sitting next to a silver Faema 20 amp grinder

    and

    c) from a shop with fridges outside?

    i think i saw it today...

    a> yes
    b> no
    c> dodgybay

    However it is unsettling that this is not a one - off

    Re: Grinder Cleaner.

    Hi Jeff,
    I dunno anything about cleaning grinders but is it worth trying with cafetto or one of those products you use to backflush/clean the parts of the coffee machine. They are designed to get rid of coffee oils and crap so maybe theyd do the job. Might be worth a try.

    Re: Grinder Cleaner.

    Thanks for the reply Sammy

    Actually, I did try some backflush cleaner as well (dont know if it is actually cafetto though), but I forgot to mention it.

    This stuff is really bad - I might still have to try something heavy duty and then wash many times in claen water to decontaminate it.

    I wish I knew which cafe the grinder had come from so I could sleep at night without wondering if I had bought a coffee from them although I reckon I would have known it.

    Cheers

    Re: Grinder Cleaner.

    Id try again with Cafetto and make sure the water is very hot and soak it as best you can for quite a while.
    Possibly a rag soaked in Cafetto sitting on the crud for a while.

    Re: Grinder Cleaner.

    Does anyone use compressed air to clean out their grinder, Ive been taking mine out the garage and gently giving it a blast with my air gun, I usually end up coatied in coffee grinds so it seems to do a good job??

    I have a small hand pump that I use to give the Macap the occasional blast between vacuums.

    Want to be a bit careful gm :-?,

    Some grinders have small galleries (channels) that could allow coffee grinds to be blown into the motor so it might be worth it to check this out first. All in all, a vacuum does the best job with one of those small flexible hose-like attachments that allows you to get in to all the nooks and crannies where grinds may be hiding, and no risk of (possibly) spreading grinds into the motor where their accumulation will eventually cause trouble.

    Cheers,
    Mal.

    Re: Grinder Cleaner.

    Try soaking in sodium percarbonate (I have a feeling thats the active ingredient in the backflush chemical anyway). Available as nappy soaker from the supermarket - the home brand ones have the most active ingredient.
    The stuff is pretty amazing at soaking off any kind of crud (I use it extensively in brewing). Just mix it with very hot water and sit it overnight, then rinse it a few times - and its non toxic so no need to worry there.
