FAQ's
What is GRINDZ™ Grinder Cleaner?
The product is the first-ever cleaner for coffee grinders.
What is GRINDZ™ Grinder Cleaner made of, and what does it look
like?
The product is a proprietary formula of grains, cereals, and pharmaceuti-
cal grade binders in a coffee bean-shaped tablet.
Why can’t I just use rice to clean my grinder?
In the past, many people have cleaned grinders with rice. However, rice
carries the risk of locking up the motor of a grinder as it passes through
and is turned into a fine powder. The hardness and shape of
GRINDZ™ Grinder Cleaner prevents this from happening. Using rice to
clean your grinder also leaves a starchy residue on the inner mechanics
of a grinder that is difficult to remove.
Who developed GRINDZ™ Grinder Cleaner?
The product was developed by the technical team at Urnex Brands,

flavor neutral. However, it should be passed through your doser and
brushed out. If you have trouble getting it all out, we recommend using a
vacuum to clean out the tiny areas.
Why was GRINDZ™ Grinder Cleaner developed?
In pursuit of ways to help customers serve the best tasting coffee, we
have dedicated ourselves to helping eliminate the chance of coffee oil
residue contaminating future brews. Cleaning a grinder has always been
a challenge since water cannot be used on the burrs or around electric
motors. The process of opening a grinder can also be very intimidating
due to the small parts and precision involved in positioning burrs. Finding
a way to clean a grinder without opening the machine became a valuable
product concept.
How does GRINDZ™ Grinder Cleaner work?
When ground through your coffee grinder, the product gently dislodges
coffee particles while also absorbing coffee oil residue.
Is GRINDZ™ Grinder Cleaner a chemical?
No. There are only food safe and edible ingredients in this product. As a
result, the product presents no risk if the residue is consumed, and it will
be flavor neutral to your coffee.
How was GRINDZ™ Grinder Cleaner tested?
Throughout the development process, the team at Urnex® worked very
closely with the technical staff at Mahlkönig in Hamburg, Germany. Every
version was evaluated for safety and effectiveness on a broad
range of grinders.
How do I use GRINDZ™ Grinder Cleaner?
Simply take the recommended dose (1 cap-full for espresso grinders and
2 caps-full for shop grinders) and drop it into an empty grinder hopper.
Adjust machine setting to medium, and operate as if grinding coffee
beans. Once complete, we recommend passing twice as much coffee
through to purge any residue.
What happens if I use a setting other than medium with GRINDZ™
Grinder Cleaner?
This is not a problem at all. In fact, you may want to experiment with
GRINDZ™ Grinder Cleaner and
different settings on your machine. We found that medium setting deliv-
ered the optimal cleaning effect.
However, this may vary with your equipment and the amount of coffee
residue.
Will GRINDZ™ Grinder Cleaner remove flavored coffee oil?
Yes. We have found the product to be effective at eliminating the scent
of flavored coffee. It is particularly effective in removing the odor of fla-
vored coffee when it has accidentally been passed through the dedicated
„non-flavored“ grinder.
Why should I use GRINDZ™ Grinder Cleaner regularly?
Just as any coffee machine should be cleaned regularly, a grinder should
be cleaned in the same manner to achieve the optimum grinding quality.
GRINDZ™ is an easy way to remove the coffee residue and oils deposited
on grinder burrs. The regular use of GRINDZ™ lengthens the time period
between one servicing and the next, and also reduces the need to disas-
semble the grinder to clean it. Thus, making maintenance less costly, and
more efficient.
How often should I use GRINDZ™ Grinder Cleaner?
It is recommended to use GRINDZ™ for espresso grinders once a week
and for shop grinders once a month.
How should GRINDZ™ Grinder Cleaner be stored?
It is best to keep in a cool dry place with the lid on.
Can I use GRINDZ™ on a fully automatic espresso machine?
While GRINDZ™ will effectively clean the burrs on most any coffee grind-
er, we do not recommend use of the product on fully automatic espresso
machines without specific instructions from your machine’s manufactur-
er. The reason we urge caution is that the brew chamber of each fully
automatic espresso machine is different. Although GRINDZ™ is fully ed-
ible and food safe, the composition of the product gives it a tendency
to expand when put in contact with large volumes of water. Therefore,
when using GRINDZ™ on fully automatic machines, it is important to not
accidentally “brew” a shot of GRINDZ™, as this could clog your machine.
In order to avoid this, ask your manufacturer how to set your machine for
grinder cleaning. If you have already tried and succeeded using GRINDZ™
on your machine, then you’ve figured it out!
Is GRINDZ™ a concern for those with gluten allergies?
We feel confident that there are no issues pertaining to GRINDZ™ and
gluten intolerance. In response to questions about this subject, the Urnex
Brands, Inc. technical staff created a detailed scientific proof to address
the issue.
The findings show that when GRINDZ™ is used according to directions,
the possible amount of gluten that could ever remotely be found in a
cup of espresso made using a grinder cleaned with GRINDZ™ is below 20
parts per million. This 20 ppm level is 90% below the gluten threshold for
a product to still be defined as “Gluten Free” in the Codex Alimentarius
Standard. This standard is an international one that dates back to the
1980’s for Gluten Free Products and is accepted internationally. Because
of the coffee/water ratios used in espresso vs. brewed coffee, these ppm
levels would be even further reduced when consideration is made for
brewed coffee. A little bit about the Codex Alimentarius Standard, and the
Urnex Brands, Inc. Proof: The Codex Alimentarius Standard is based on
analysis of the nitrogen content of gluten-containing cereals. This stan-
dard permits a maximum of 200 parts per million (ppm or mg/kg) gluten
in a finished product allows for a cereal-derived product to be labeled
“gluten free” if it does not exceed that limit. Urnex chose 20ppm as our
threshold based on a variety of factors and our desire to be excessively
thorough and conservative.
Some packages contain “Best Before”, and some do not...why?
As with any new product, the shelf life of GRINDZ™ was something that
was not entirely certain prior to launch. In an effort to be overly cautious
and conservative, Urnex chose to print a “best before” date
on each jar during first few months of production and distribution. How-
ever, after 1 year of in-market experience along with simulated lab stabil-
ity tests, Urnex has concluded that there is no longer a need
for the “best before” date. We now believe a reasonable period of storage
prior to sale is a minimum of 18- 24 months - if not longer - assuming a
clean, and relatively dry warehouse setting.
