For years my cleaning technique for my Compak K3 T and Rancilio Rocky before that has been an expensive dose of Grindz, an occasional vacuum and a FAR more occasional disassemble and clean.
But sheesh! Grindz is a pricey item, especially if you use it as often as you should. What is the current consensus on cleaning a grinder with uncooked 2-minute white rice?
Save the rice for your curry PW, it may or may not work but I'm never gonna know Would rather spend half an hour every now and again cleaning it (Mini Mazzer) manually, it's an easy job.
I've been using rolled oats (not as hard as rice) bought from supermarket it seems to do its job. never used Grindz so really can't compare though.
There are three questions here, yeah?
- Does it do the job?
- Does it damage the grinder?
- Does it leave residue?
I've not heard much "why" from anyone opposing the use of the "popular alternatives", but then I've never tried it myself since the burrs on my Preciso are easily-cleaned/accessible.
I ran par boiled rice (bought at my local Asian grocer) through my HG one. I was using it to season the burrs but I'm sure that it would do a fine job of cleaning them too. I'd much prefer to run it through an electric grinder... it was quite a workout with a hand grinder!
Rice has no more place in a coffee grinder than coffee does in a rice cooker!
It's easy enough to clean most grinders by hand so harden up and give it a go.
Well thanks for the cleaning viewpoints and for the rice-related humour.
Like most things, there are generally no shortcuts.
I bought a large pack of Grindz years ago. Still going. Though I only use it every few months, and only a small amount. If you do use rice, I think it should be cooked and hardended rice, not "raw" rice.
I have always cleaned my breville smart grinder with raw medium grain rice and never had a problem with it the breville happily chomps away at rice. The rice is very good at absorbing moisture and oils and cleans the grinder a treat. I also pull apart the grinder burrs and inspect for damage every time as well.
I'm not sure exactly why people have this great desire to feed rice into their much loved and cared for grinders, removing the burr carrier every now and again and giving the grinder a good clean out is a quick and simple process.
I suspect the rice/Grindz solutions are used by those who don't feel confident in pulling the top off the machine, or, perhaps it's simply a lazy way of doing the job.
Another option i have contemplated would be to use a hopper full of dry ice ( CO2) pellets as used for industrial cleaning !
They are hard enough to mechanically clean the components without damage, but evaporate quickly to leave no residue at all.
As far as voiding the warranty, don't know about the K3 but my Mazzer manual gives detailed user instructions as to how carry the process out, including removing and replacing the burr carrier (grinding blade holder) as they refer to it, so cleaning the machine in this manner doesn't void the warranty as far as Mazzer are concerned.
Not sure about the dry ice process, there is no mention of it.
No worries Yelta...I've pulled it apart subsequent to the expiry of the warranty....was in good nick. The instructions that come with a K3 are not the best....but they outdo the instructions that came with my Gene Cafe which recommended that I wash the roasting chamber in soup. Haven't tried that yet....probably go for a Laksa.
I tried using rice...
...but now all my coffee tastes like week old prawns.
Anyone know how to remove the prawn smell?
Will the purpose designed (and often supplied from the factory with many grinders) Grindz help?
Or maybe I should just remove the top burr set and brush it out with a pastry brush / toothbrush?
As long as you are an expert in metallurgy and will know that you won't make the tool steel burrs brittle by subjecting them to -80CAnother option i have contemplated would be to use a hopper full of dry ice ( CO2) pellets as used for industrial cleaning !They are hard enough to mechanically clean the components without damage, but evaporate quickly to leave no residue at all.

SNAP - Burr!
I'll let someone else go first thanks. For mine, disassembly and sometimes Grindz if I am feeling lazy.
By cooked rice I meant, cooked and and dried, as opposed to raw which is much harder. But Grindz is not that expensive (leaves a white powder everywhere though).
Woildnt rice leave white powder everywhere too
unless you use brown rice?
The standard grindz is made of grains and cereals, including wheat and pharmaceutical binders.
They make a gluten free, organic one now, as well.
Here is a link to the msds. (materials safety data sheet)
An air compressor seems to do the job for me.
The rice option sounds interesting, but I hate wasting food .
Don't use uncooked rice. Changed burrs on a rocky, noticed some surface rust on the burrs so ran uncooked rice through. Opened it up to clean out residual rice, ran fingers across the burrs and they are now somewhat blunt.
Rice is a grain (seed) 100% organic and orders of magnitude softer and weaker than steel.
I dont get this prejudice against rice as a alternative to "commercial" cleaners ?....i sure it was being used successfully before Grindz was even though of !
I would hate people to get the idea that cleaning a grinder with rice is the accepted way to go when there are better methods available.
The fine edge of any cutting instrument can be dulled (damaged) by pretty much anything over time. These microscopically thin edges are bent, chipped, sheared and otherwise deformed as the beans (or rice) are ground and these damaged edges are then subject to oxidation as well as newly exposed steel is exposed to oxygen and acidic oils.
This thread is the biggest amount of nonsense I have read in a long time. Anyone forking out $500 plus on a grinder, needs to have their head examined if they use rice as a cleaner. The amount of people with OCD here is unbelievable! Use a brush and a vacuum, that is all that is needed. Do not feed it oily stale beans. My M4D is over a year old. I only clean it with a brush. I have vacuumed it once. It works perfectly. Please get over yourselves with all of this nonsense and insecurity of keeping your grinder spotless. If it is very dirty and clogged up, then use Grindz. Do not be a cheapskate. I certainly would not buy a second hand grinder from anyone advocating the use of rice as a cleaner.
I'd like to see if you could grind the rice in the grinder to a nice coarse consistency then bung it in a milk jug with some good quality chicken stock and steam up a nice Risotto.
