Cafetto Grinder Clean Tablets 430g

Cafetto Grinder Clean is a 100% natural grain-based cleaning tablet designed to remove coffee oils, residue, and stale odours from burr and conical grinders without disassembly. The coffee-bean shaped tablets are simply poured into the hopper and ground through — the abrasive action of the grain formula scrubs the burrs and internal casing clean, and a quick follow-up with coffee beans re-seasons the grinder ready for use. No tools, no downtime, no dismantling required.

Why Grinders Need Regular Cleaning

Coffee oils accumulate on grinder burrs and casings with every use, and over time they turn rancid. The effect is gradual but real — the freshest beans start tasting flat or bitter, grind consistency becomes less predictable, and in some cases oil build-up can cause the grinder to slow down or jam. This is particularly common with dark or oily roasts, which shed significantly more oil than lighter roasts. Regular cleaning with Cafetto Grinder Clean removes this build-up at source, restores burr performance, and eliminates the off-flavours that stale oils introduce into every shot or filter brew.

100% Natural, Registered for Organic Use

The formula is 100% natural grain-based — no binders, no chemicals used in processing. It is phosphate-free, GMO-free, biodegradable, gluten-free, and registered for use in organic production systems. This makes it a safe choice for both conventional and organic coffee setups, and for grinders used across a range of roast profiles including specialty and single-origin coffees where flavour clarity matters most.

Approximately 10 Cleans Per Jar

One 430g jar provides approximately 10 cleaning cycles, using one capful of tablets per clean. This makes it a practical and economical grinder maintenance product for both home users and cafés cleaning grinders regularly.

How to Use Cafetto Grinder Clean

Empty all coffee from the hopper. Pour one capful of Grinder Clean tablets into the hopper. Run the grinder and allow all the tablets to grind through completely. Empty the dosing chamber and brush out any dust from the hopper, spout, and doser. To season the burrs after cleaning, pour one capful of coffee beans through the grinder and discard. The grinder is now clean and ready for use.

Note: a small amount of fine dust may develop during grinding — this is normal and harmless.

Frequently Asked Questions

Does the grinder need to be disassembled to use Cafetto Grinder Clean?

No — this is one of the main practical advantages of the product. The cleaning tablets are poured directly into the hopper and ground through exactly as you would grind coffee beans. The grain-based abrasive formula cleans the burrs and casing during the grinding process itself, with no tools, no removal of burrs, and no downtime beyond the few minutes the cleaning cycle takes. A follow-up run of coffee beans re-seasons the burrs before normal use resumes.

What grinders is it compatible with?

Cafetto Grinder Clean is designed for standalone burr grinders and conical grinders — both home and commercial models. It is compatible with espresso grinders, filter grinders, and most flat and conical burr grinders. It is not suitable for use in grinders that are built into superautomatic espresso machines, where the grinding pathway cannot be properly purged after cleaning.

Is it safe to use with organic coffee?

Yes. The formula is registered for organic use — it is 100% natural grain-based, phosphate-free, GMO-free, and contains no synthetic binders or chemical inputs. It meets organic certification requirements and is safe to use in setups where organic coffee is being prepared.

How often should a grinder be cleaned?

For home grinders used daily, cleaning every two to four weeks is generally sufficient to prevent significant oil build-up. For café grinders handling high volumes or dark/oily roasts, more frequent cleaning — weekly or even more often — will produce more consistent results. The 430g jar provides approximately 10 cleans, making it straightforward to build a regular cleaning schedule.

Will it leave any residue or taste in the grinder?

No. After grinding the tablets through and following with one capful of coffee beans to re-season the burrs, the grinder is clean and ready for normal use with no detectable residue, dust, or flavour carry-over from the cleaning product.

Is it the same as Grindz tablets?

Cafetto Grinder Clean and Grindz (by Urnex) are the two most widely used grinder cleaning tablet products in the coffee industry. Both use a natural grain-based formula and work on the same principle. Cafetto Grinder Clean is made in Australia and is registered for organic use; both products are well regarded by home baristas and commercial café operators.
