Cleaning the espresso machine can take from five minutes to half an hour,
depending on your experience, diligence, and the machine’s overall use. Daily
cleanings should take between five and fifteen minutes, while weekly cleanings
should take longer. This document lists the steps that you should go through
in cleaning the machine, and provides some helpful tips that will make your life
easier and somewhat safer.
The Espresso Bar has several components. From left to right they are the
refridgerator that holds the milk, the stainless steel table, the espresso machine,
the coffee grinder, the knockout-pan (where the dead coffee goes), and the filter
bucket. Underneath the table should be a “cleaning kit” that has a bunch of
tools that will help speed things up.

Before You Get Started
There are some constraints on how you go about cleaning. If you break these
constraints, you can cause plumbing problems or a big mess in the lounge.
While these events do not signal the end of the world, they can cause some
embarrassment and time on your part as you deal with them.
First, you may not put coffee grounds or particulates in the sink. The sink
has a filter that can clog and cause a backup. Solid coffee grounds, for example
from the knockout-pan, go in the trash. Liquid coffee grounds, for example from
rinsing one of the porto-filters, go into the filter bucket.
Second, cleaning involves water, moving things around, and a large number
of paper towels. Please make sure that when you are done cleaning the machine
that you do not cause a mess in the lounge.
Third, the filter bucket catches drainage from the espresso machine. The
filter bucket should be able to go for 4-5 days (depending on usage) without
emptying. The filter itself should be changed every 1-2 weeks. The liquid in the
bucket can be dumped into the sink, presuming that there are no gaps or rips
in the filter.

The Cleaning Kit
The cleaning kit has the following items:
Large tupperware container This doubles as the container for the cleaning
kit when it is not in use, and the wash basin when it is. Since the sink is
restrictive, and you want to avoid washing dishes in the tiny drain of the
machine, the tupperware basin provides a buffer.
Tongs Many of the metal items, especially the grates, will be hot. Use the
tongs to pick them up.
Sponges Sponges are for cleaning tops of surfaces and for washing dishes.
Don’t use them to wash down the machine.
Dish towels These are different than the white towels, and are for drying
dishes.
Glass Wipes The chrome-plated machine should not be scrubbed. Instead,
the guy who installed it said to use windex; these are the same, only more
convenient. When you use these, the machine will gleam and sparkle, and
cause fear in the natives.
Do not pack up the cleaning kit unless you have dried it off, or else it will
get moldy. It goes underneath the counter when you’re done.

Periodically Throughout the Day
Check supply levels. Make sure the steaming nozzle is clean. Clean up the worst
of the mess on the counter.

Washing Dishes
Washing the dishes requires about 10 minutes.
1. Retrieve the cleaning kit from underneath the table.
2. Empty out the tupperware container. This is your wash basin.
3. Fill the tupperware container with water and a bit of soap.1 Place the
basin in the sink so that you don’t splash water everywhere. I find it
helpful to put the basin over the sink’s drain, so if some coffee grounds do
spill over, they don’t go down the drain.
4. Wash the shot glass, the tiny metal espresso jugs, the spoon, and any dirty
demitasse cups in the wash basin using the sponge.
1 There is no hot water in the lounge, so to get warm wash water, fill the basin about
halfway with cold water from the tap, then use a bit of hot water from the machine.

5. Rinse and dry.
6. While the top of the machine is clear, remove the top grate and rinse into
the basin. Clean off as many grounds as you can from the top of the
machine. You can polish both the grate and the top of the machine with
glass wipes if you want.
7. Dump out the grounds from the knockout-pan into the trash and wash it
in the basin.
8. Replace the grate and put all the dishes back on top of the machine.
9. Dump dishwater from the basin into the filter bucket slowly, taking care
not to overflow the filter reservoir.
10. Pack up the cleaning kit.

Cleaning the Bar
Cleaning the bar entails wiping down the counter, and straightening up.
1. Brush off any coffee grounds into your hand (not onto the floor) and dump
into trash.
2. Wipe down the countertop.
3. Put away the chocolate syrup if it’s out.
4. Detach the plastic bottom tray of the grinder, brush into trash or knockout
pan.
5. Be sure to replace the knockout pan and anything else to its canonical
position.

Daily Cleaning of the Machine
Water spots and splatters can be cleaned off the machine only with the Glass
Wipes. The basic daily cleaning should take only five minutes, but a more
thorough one can require fifteen or twenty.
1. Check supply levels. If we’re running out of anything, let the appropriate
person know.
2. Rinse the portofilters with hot water.
3. Empty and wash the milk pitchers. You can do this in the sink without
the basin.
4. Wash the thermometers. Remember to put the thermometers back in the
pitchers, and the pitchers back in the refridgerator.

5. Remove the filter from the single shot portafilter. You can use the spoon to
gently pry the filter from the handle. Do not use your fingernails, because
you are likely to lose one (fingernail) this way. Wash and rinse the filters
in the basin.
6. With the angled wire brush, clean out the flange and screen in the espresso
spigot where the coffee grounds accrue.
7. Flush the spigot with water from the K-button.
8. Clean the steaming nozzle carefully.
9. Take a blank, put into one of the filter handles, and put into machine.
10. Backwash the machine for 10 seconds. Turn machine off for 3 seconds to
allow to drain. Repeat for a total of five times.
11. Remove blank. Replace filter.
12. Lift bottom grate with tongs. With paper towel, wipe the grate off into
the trash.
13. Lift bottom pan. Pour residual liquid into filter bucket.
14. Use a paper towel to remove the water from the coffee-grounds trap.
15. Use a paper towel to remove as many grounds as you can from the trap.
You won’t get all of them.
16. Replace the bottom pan and grate.
17. Turn off machine
18. Any rags that are too dirty to use the next day should be put in the dirty
rag bag. When we’re down to a couple of rags, it’s laundry time.
19. Perform the tasks for Cleaning the Bar.
20. Sign your name in the log book.

Weekly Cleaning of the Machine
When cleaning the machine, work from the top to the bottom. The main difference between daily and weekly cleaning is that you perform 3 backflushes
and make sure all the dishes are clean. The weekly cleaning should restore the
machine nearly to the state it was in when we bought it. This will take 20-30
minutes, but will prevent a larger quantity of work later.
1. Make yourself a mocha, or hot chocolate, or latte with the leftover milk
in the pitchers. When you do this, also check the milk inventory. Besides
getting a free mocha, you also make sure the machine is in a known state
before you start.

2. Perform the steps in Wash the Dishes
3. Perform the Daily Cleaning. After the first backflush, take 1 tsp of Purocaff soap and put in the blank. Backflush. Remove blank. Backflush twice
more.
4. Take filters out of portafilter handles and place in steaming pitcher. add ≈
1 tsp of purocaff. Cover in hot water from machine. steam with steaming
wand until nearly boiling. Let soak for 10 minutes. Empty and rinse
pitcher, rinse filters, dry.
5. Perform the steps in Cleaning the Bar.
6. Move the coffee grinder and clean the counter underneath it. Make sure
the counter does not have coffee grounds or water spots on it.
7. Wipe down the refridgerator, outside and in. Remove any spilled milk.
8. Dump liquid from filter bucket into sink (remove filter collander first).
9. If necessary, perform steps in Change Bucket Filter.
10. Sign your name in the log book.
11. Take dirty rags home and wash them if necessary.
12. Enjoy your mocha.

Change Bucket Filter
This is easy but annoying. It should only need doing every 1-2 weeks. The
filter that I am currently using consists of two Kleenex Viva towels, which are
high-strength paper towels. The pore size on the towels is small enough to filter
out coffee goo and oil globules that can clog the drain.
The filter consists of a colander, a vegetable steamer basket, and the filter
medium. The colander fits perfectly into the mouth of a 16-quart enamel stockpot. The steamer basket serves as a way to both provide a better shape for the
filter medium and to provide a buffer space between the colander and the filter
medium; if you see grounds or goo on the bottom of the colander, it means that
the filter did not work.
1. Remove the filter colander. Throw away the filter.
2. Take 2 new Viva towles, and get them sopping wet under the sink.
3. Place filter colander in the sink.
4. Place 1 Viva towel in the colander so that it lies flat against the sides of
the colander and the floor of the steamer basket.
5
5. Place the other towel at a right angle to the first so that all pores of the
colander are covered. Try to eliminate folds where possible.
6. Replace filter colander into stockpot.
7. Replace stockpot under machine, and place the hose into the filter colander
so that the hose is resting on the filter.
