Topic: Cleaning Rocky (29 msgs / 647 lines)
1) From: Dana Kaempen
Good day.
I've been lurking on the list for years, but I finally have some Actual
Content to ask for!  :)  I was one of the mass purchasers of the
Rancilio Rocky coffee mills a few years ago.  It's been some time (2-3
years?) since it was bought and I imagine that with all the use my mill
has had, it's time for a cleaning.  I can do some basics with a pipe
cleaner, but I feel that I should do a *really decent* cleaning every
so often - now would be good.
My Qs:
- Has anyone thoroughly cleaned their Rocky and if so, how did you do
it?
- Does anyone have a link to a website (commercial or homegrown) that
shows how a Rocky should be cleaned?
- Am I bringing up a topic which has already been thoroughly discussed?
 If so, can someone point me to where this list's archives are stored
and either a Subject line or an approximate time to search for?
Thank you all in advance for any assistance you can give me.  As usual,
mega-thanks to Tom & Maria for continuing to host us all and for being
the most comprehensive online source for high-quality green coffee
beans on the Internet!
Dana

2) From: miKe mcKoffee
I do two types cleaning with Rocky, quick frequent and thorough periodic 
(few times a year)
Quick frequent can be a couple times a month or more. If Rocky smells like 
stale coffee it's time. I simply run a double PF load of Minute Rice 
through. Followed by good brush out and or vacuum. (Before someone says it 
gummed up my Rocky, I'll mention don't cook the Minute Rice first;-) Minute 
Rice, the par-cooked stuff, because it's softer which absorbs coffee oils 
etc. Some people think Minute Rice will hurt the burrs, personally I don't. 
Minute Rice is softer than roasted coffee. Par-cooked rice versus hardened 
steel burrs...
Periodically pull the hopper (3 screws and don't drop one down the drain;-), 
unscrew counter-clockwise and remove upper burr carrier, brush and vac 
anything and everything, including clean burr carrier screw threads 
(especially the internal female threads tend to gunk up it seems). Oh, might 
have to remove finger guard before hopper, I don't really recall 'cuz mines 
been off so long.
YMMV, this works for me. Hope this helps.

P.S.  Sorry for my late response to your quick responses.  SBC decided
to shut down my account because they'd incorrectly "converted" it 6

I know this sounds dumb but I messed up my old grinder trying to give it =

coffee grinds beneath the shield in the holder - should I attempt to =
take that apart?  The book doesn't really give a good description.
Thanks,

9) From: Brett Mason
Here's what I do...
  << Some people remove the shield.  (Don't put fingers into a turning
grinder)>>
Wipe out the grinder best you can.
Use (dry uncooked) rice to clean the grinder.  Some recommend using minute
rice - I use regular rice.  Rice will pick up much of the oils and
moistureinside, and will get the grit out of your burrs...

Having a commercial air compressor in the shop makes it easy!  It is amazing
what a 120 psi blast of air will do to coffee gunk!  Now for those without!
Unplug the grinder.  Take it apart all the way down to removing the burrs.
Clean all removed parts with soap and water, rinse and dry.  Clean out
everything else with a damp towl.  This should be done on a regular basis.
You know how often when cleaning gets difficult you have waited too long.

I don't understand what Mark is saying it takes special tools to take the
bottom burr off.  A good screw driver and a wrench to hold the nut is all
you need.  There is a lot of crude that can collect under that bottom burr.

Ditto! Had Rocky's lower burr out numerous times for replacement and/or
internal cleaning of Rocky. Don't need no stinkin' tool. (and have no idea
what it would be anyway) Imperative that it be a quality tight fitting to
screw head driver and apply substantial down force to break loose without
stripping screw head.

15) From: David Morgenlender
A few weeks ago I posted a message asking about a solution for bitter =
tasting
brews.  I received suggestions to clean my grinder, a Rocky.  Instead of =
the
full cleaning recommended, I used some instant rice ... problem solved.  =
But a
couple of days ago, the problem returned with a vengeance.  One day I had=
 no
problem, the next day I had the most bitter brew I had ever experienced, =
whether
using my Scandi or Chemex.  So yesterday I bit the bullet & performed a =
thorough
cleaning of Rocky.  The next brew was one of the most delicious I've ever=
 had
... Panama Panamaria Decaf in my Scandi ... like a cross between coffee &=
 an
unbelievable jasmine tea with lemon;  about as clean a flavor as I've =
had.
I'm wondering why Rocky would get this bad so quickly.  In my Braun =
grinding
days, the results weren't as good as Rocky at anywhere near its best.  =
OTOH, I
never ran into the level of bitterness I encountered with Rocky ... and =
this was
with no cleaning over many years!
The day before I encountered the problem, I did a lot of grinding for =
espresso,
which I've done relatively little of with Rocky.  Would the fine espresso=
 grind
lend itself more to this problem than coarser grinds?
When I opened Rocky, the cleaning job was not at all what I had expected.
Virtually no grinds caked on, no obvious oily deposits, etc.  But an =
amazingly
large amount of old grounds just sitting around.  I'm talking piles of =
grounds.
The inside of the grinder smelled horrible from the odor of old grounds;
cleaning it got rid of most, but not all, this odor.  Is all this =
typical?

Dave,
Yours is the first post I've seen that makes specific empirical reference to
the results obtained from thorough equipment cleaning.
Prior to cleaning Rocky, you had a - - seasoned - - grinder.
Seasoned coffee processing equipment always has some coffee residue in it. I
think everybody cleans the most visible coffee server, the cup.
Why stop with the cup? I think coffee stales wherever it's open to oxygen,
especially in the grinder where it's ripped open and unzipped.

17) From: Lynne
I just finished cleaning my Zass. I have to say ^#*&$^!!
Why - why on earth are these machines (are ANY grinders easy to clean?) 
made so it is so difficult to clean? Maybe cleaning the Rocky is easier 
(both my finances and extreme space limitations in my new apt. will 
prevent me from getting one.)
In the process I noticed that one of the little nuts on the bottom is 
missing. How on earth that happened I'll never figure out. If it just 
fell off since the last time I cleaned the Zass, then it HAD to fall 
into my coffee grinds (which brew tasted particularly odd, I 
wonder...). So I didn't notice?! Man, I need new glasses...
Anyway, it is such a pain to clean this. To me, an appliance should 
function on all levels. Ease of cleaning an apparatus like this is 
important. Every time I clean mine a huge amt. of old coffee falls out. 
There is no way I'm going thru this (just removing & replacing the 
screws on this thing takes so much time - and dexterity that I seemed 
to have misplaced back in '92 or so) EVERY time I make a brew - yet 
that means I'm getting old coffee when I grind!
Maybe that's why I don't notice a huge difference w/my whirly grinder!

Cleaning the Rocky is definitely NOT easy.  Although there was a lot less
scrubbing than I had expected (based upon online instructions), actually =
just
about none, there were MANY nooks & crannies containing grounds.  Most of=
 the
old grounds were in areas that would not get them into new grounds.  But =
there
were more than enough within the burr area that would get into new =
grounds.  My
hope is they would be recycled as new grounds appeared, so they would not=
 be
very old when brewed.
I attached the nozzle to the portable vac & got out what I could =
periodically.
But this couldn't get close to everything. 
There is only a tiny slot into the chute.  So I'd have to brush grounds =
to fill
the slot (not a lot of grounds), then use canned air to clear the slot =
down the
chute.  Then I'd start over.  Occasionally I'd use the air spray to get =
grounds
out from under the burrs (& all over the kitchen :) !).
When it came to the non-burr area there's really no good way to do it.
Actually, the best approach could be to periodically turn the grinder =
upside
down & shake it.  But the thing is heavy & would make a mess.  I guess I =
could
dump everything on the floor & vacuum it from there ... it would be =
easier!
Actually the real problem with this approach is I could drop Rocky!

I wonder how much stale coffee it takes to make a brew taste so bad.  =
It's hard
to believe a lot of old coffee could hang around a long time, then get =

grinds which would be used.  They could easily hang around in the huge =
amount of
accumulated grounds which would not be expelled when grinding.
It makes me think that fine espresso grounds stale much faster, so stale =
coffee
does get into future grinds.  But if this is the case, it could mean this=
 can
recur unless Rocky is cleaned after each day's espresso grinding ... too =
much
work!  Or maybe grinding a small amount of beans very coarse after =
espresso
grinding would clear out the fine stuff.

20) From: Vicki Smith
I run minute rice through my Rocky at least once a week, but I seldom 
dismantle it to do a thorough cleaning. I did it today though and was, 
once again, amazed at how much coffee collects in various places in the 
darn machine. This is definitely not an inside job around my house.
In any case, I was wondering if the coffee that collects in all of those 
odd places just stays there, or does some of it break off (sorta like an 
avalanche separates from a mountain of snow) and send that stale stuff 
into my cuppa?
Vicki

21) From: Barry Luterman
That could happen but the larger concern is the formation of rancid oils 
from all the collected stale coffee

22) From: Vicki Smith
I had been assuming that the minute rice routine was taking care of that 
part Barry. I wonder how often folks here completely disassemble their 
grinders. Mebbe I am just a lazy slug. The Solis Maestro (which is what 
used before going over to the dark side) was much easier to clean.

My personal experience with the dark side is the more attention I spend on 
cleaning and maintaining my equipment the better the end product.

24) From: miKe mcKoffee
IMO Minute Rice does a good job cleaning the grinds path between thorough
take apart cleanings. Take the "stop screw" off the bottom of the hopper and
in the future the hopper can simply screw out with the upper burr attached,
no screws to remove.

FWIW "thorough" thorough cleaning includes removing and cleaning under the
burrs. You might be surprised what gets under there! (not just Rocky, goes
for Mazzers etc. too:-)

Remove the lower burr too, trust me! Just did the used Rocky I recently
acquired and sold but not shipped yet. While it "looked" very clean before
"going deep", DISGUSTING under both upper and lower burrs!!! (New burrs
arrive for it tomorrow so just getting a head start on a lazy 4th of July
afternoon:-)
BTW, the lower burr can seem "stuck" in and impossible to get out. After
removing the screws, lightly grip the burr with needle nose channel locks
(or pliers) and lift straight up working around in a circle if needed until
comes out. Then really a piece of cake. Clean out the head groove thoroughly
before attempting to unscrew. Also, use extreme downward force while gently
increasing turn torque on the head until breaks loose so driver doesn't slip
and strip, can be pretty stuck. (Lower burr use 12mm socket or wrench to
keep from turning:-)

I think I will take the machine in with me next time I drive to 
Edmonton, so Joe (who reassembled/repaired my Rocky following its 
tumble) can show me how. Although I am only 50 or so pounds into this 
set of burrs, I'm eventually going to hit the 100 pound mark and will 
need to know how to remove the lower burr anyway.
Thanks again.
