Hi,

What are the recommended ways to get the organic material out of the
tiny holes in the portafilter?

I have used a very fine toothbrush but is there is prefered chemical
means? Say boiling, saturated baking soda or something simular. I'd like
the organic stuff to be gone . . . without too much of a kitchen safety
issue (I like my fingers!)

Espresso machine cleaner. I recommend Cafiza by Urnex but any such
product will do. Mix with hot water and soak overnight if necessary.
Do the saem for the portafilter body, shower screen, shower head, and
any other removeable parts that are cleanable. Only precaution is to
be sure that the cleaner is OK with your machine (some cleaners are
rough on aluminum for example) and to rinse everything thoroughly.
DIscard the first shot to be sure.

Also, if you machine has a 3-way valve, check into backflushing...

Looking at Randy's and Ian's comments and your original post I think I
misinterpreted what you're trying to clean - I guess you want to clean
the basket, which is held in place by the PF.

FWIW I second their advice, but I would separate the basket from the
PF before doing that, and clean each part separately (as I imagine
both of them would do as well). If you are seeing a lot of scum on the
top side of the basket, I'd bet you'll find even more beneath it and
want to remove that too.

On many machines the basket can be removed from the PF either by hand
or with a simple slot screwdriver and some leverage, but if you have a
special "crema enhancing" pf maybe there is more involved. I don't
know, as I know nothing about them. For this reason I don't want to
tell you to just pry off the basket as that may harm it.

What machine do you have?

Correct. It is the basket I'm trying to clean. I have two and one needs
to have the little holes cleaned.

It is just the stuff that has filled the little holes I'm after.

Got it. Soak it (as recommended by I/R in the detergents they
recommend). I don't think there is a tool small enough to punch the
crud out of those holes and you'd be there forever in any event...

Use a sewing needle or hypodermic needle, and don't stick yourself.

Use the cleaners and the holes are as clean as new...

Soak in Cafiza or similar cleaner.

Add a table spoon of Cascade to a basket and pull a couple of shots.

If you mean the spouts I've had good luck soaking in espresso
detergent overnight in (initially) hot water. For really big deposits
I suppose I'd try some craft store type pipe cleaners.

Hope that helps.

I find that a scrub with a brush of the type intended to clean
fingernails ('nailbrush'?) with ordinary dish-washing detergent leaves
them spotless. Check that the bristles are narrow enough to fit
through the basket holes, and shorter rather than longer, for best
results. Definitely don't use abrasives.

Yet another method:

compressed air! from the 'back' side


Never use a needle or a pin -- it may enlarge the holes, ruining the
thing.

An alternative to espresso cleaner (or as well as if you've inherited
abused equipment) is an ultrasonic cleaner. They start at $20 and go up
past ones big enough to stick an entire espresso machine in ;)

Warm water, dishwashing liquid or espresso clean, and 40khz vibrations
will work wonders.

Take the basket(s) to a local Optician/Optometrist, (or
whatever you call them). They often have ultrasonic cleaners
for gently and rapidly de-gunging spectacles of hidden grease
and/or inaccessible particles..

..alternatively, apologise to any near neighbours, bribe
the partner, place basket in small, lidded container with
cleaning liquid, place directly against sub-woofer, turn
MeatLoaf's "Bat Out Of Hell" (whatever or similar) up to
a full resonating volume with playback loop engaged...

..sit back in aural bliss (or with exquisitely canned Mozart)..

Voila! ;))

As usual I agree with Barry - try fire. Maybe the self cleaning cycle of
your oven.
Back when I had a two stroke bike I used to clean the muffler baffles with a
propane torch - just heat it up to red hot, wait until the smoke cleared and
then tap out the ash.
But that was before I had a self cleaning oven. :)

Hmm, not sure if you're kidding but serious heat will anneal the metal

Well, no one else has asked, so I will. Why do you think there is any
significant organic material in the tiny holes, and why do you care?

When you look through the bottom of the basket held up to the light, you
can tell a lot of the little holes are blocked. The problem is they
reduce the flow to a trickle and the crema (sp?) disappears. It also
tastes a little 'flat' . . . not as aeromatic.

When I put my spare basket it, suddenly my 20-30 second shots were back
with a lot of crema and flavor.

I wonder if when, as the baskets are not so excessively
expensive and the holes really do become virtually and/or
irretrievably blocked - or so enlarged with enthusiastic
pin-holing - that replacing them might not be the wisest
course of action?

Treat your baskets as periodic consumables ..cost
isn't all that much different to a packet/bottle of
descaler anyway.. :))

This is what happened to the original basket which failed after three
years of use. The flat bottom surface bowed down and failed. I was using
the single shot basket until this pair showed up.

The bottom of the portafilter basket is weakened by the small holes and
subject to considerable stress everytime a cuppa is brewed. They don't
last forever and certainly, replacement with a pair every two to three
years is OK. Just you like to get as much usage as possible before
sending it to the scrap metal dealer.

Yes.. I can understand that, Bob. :))

Although aware of the pressures involved, I suppose I
hadn't really given the failure of a basket much thought
until you introduced this thread and then others added
to and around it...

Not that it means anything, (different discussion), but
one or two of us did notice recently when looking for a
suitable single-pod basket to work sensibly with Gaggia's
pf that most basket costs were, if anything, about the
same as the cost of a packet Gaggia's de-scaler.. (This
in GB, by the way)...

..and thank you for your added explanatory notes.. :))

Over time, even though I scrub the baskets vigorously every day, crud
built up in the holes. Oil sticks and super fine particles stick to
it, eventually reducing the hole diameter to the point a decent pull
was not possible.

I first discovered this a long time ago when I was trying to figure
out what had gone wrong with my shots. I held an unused single basket
and a VERY used double up to the window and was astounded at the
difference in apparent hole size. I, too, had thought scrubbing every
day would keep it clean.

A soak in Cafiza and a shot of Cascade and the holes were again the
same. I'd assumed descaling would have cleaned it, but was not the
case.

Not sure if this is somehow related to machine and / or the grinder
producing more fines and / or ????. At the time I was using a Maestro
with an Solis SL90.

Well, looks like I'm being proved wrong. Maybe the crud turns to CO2
way before the metal has reached the same temperature (what, red heat
to oxidise carbon?), but it just strikes me as an extra risk when
baskets already break from time to time without any help. Then again,
St. Schomer recommends cleaning them with scotchbrite and i don't like
that either ;)

Out of interest, how long do baskets last in the commercial environment?

I tried gas heat on one of mine and it is now permanently discolored (a blue
hue :) but still very functional. Super clean on the holes. Thanks Barry.
imo I don't think that 9 bar will blow through the metal, even weakened,
before it blows through the holes. Time will tell.

Thing is, the puck is the flow restrictor that allows the brew pressure
to build up and since the basket is the only thing holding back the
puck, it sees the total pressure. Depending on the evenness of the
dose and tamp, the pressure is exerted across the whole basket surface,
so even the area around the holes will be stressed via the puck.
