Urnex Grindz Coffee Grinder Cleaning Tablets 430g

Your grinder is doing a lot of work. Every dose that passes through the burrs leaves behind a small amount of coffee oil and fine particulate residue, and over time that accumulation affects grind consistency, clogs the burr geometry and introduces stale, rancid flavours into every shot or brew that follows. It's one of those things that happens gradually enough that you might not notice until the damage to cup quality is already done. Regular grinder cleaning is genuinely important, and Grindz from Urnex is the most practical way to do it properly without taking your grinder apart.

What makes Grindz clever is the format. Rather than requiring any disassembly, water or brushing out of individual burr chambers, you simply run the tablets through the grinder as you would a dose of coffee. The proprietary tablet formula, made from natural grains, cereals and pharmaceutical-grade binders, passes through the burr set and absorbs coffee oils and residue as it goes. The process takes minutes, requires no special tools, and leaves no harmful residue behind. The formula is food-safe, gluten-free and has been patented since its launch in 2005 following extensive field testing. After the Grindz cycle, a couple of purge doses with coffee beans clear any remaining traces before you're back in service.

The 430g tub is well suited to café environments or anyone maintaining multiple grinders, and the process scales easily across different grinder types. Grindz works on both flat and conical burr grinders, covering the full range of standalone espresso and filter grinders you're likely to be running. It's worth emphasising the standalone grinder requirement here: Grindz is not suitable for grinders integrated into automatic espresso or bean-to-cup machines. For those setups, specific cleaning tablets designed for integrated systems are the appropriate choice. For everything else, this is exactly the product you need.

FAQs

How does Grindz clean a grinder without water or disassembly?

Grindz tablets are made from a proprietary blend of natural grains, cereals and pharmaceutical-grade binders that pass through the burr set just like a dose of coffee. As the tablets are ground, they absorb coffee oils, remove residue from the burr geometry and clean the internal casing. The process is entirely dry and requires no disassembly, water or specialist tools.

Which grinders is Grindz suitable for?

Grindz is suitable for standalone coffee grinders with flat or conical burr sets, including both commercial espresso grinders and domestic grinders. It is not suitable for grinders that are integrated into automatic espresso machines or bean-to-cup machines. For integrated grinder systems, you'll need a cleaning product specifically designed for that purpose.

How much Grindz should I use per cleaning cycle?

Use one capful (35 to 40g) for espresso grinders, or two capfuls (70 to 80g) for larger shop grinders. A dosing chart is available for reference. Set the grinder to a medium grind setting for the cleaning cycle rather than your usual espresso or filter setting.

Do I need to purge the grinder after using Grindz?

Yes. After running the Grindz tablets through, purge the grinder by running two doses of coffee beans through at your normal grind setting. Discard the grounds produced during these purge cycles before returning to service. This ensures no trace of the cleaning tablets remains in the grind path.

Is Grindz safe for food environments?

Yes. Grindz is made from food-safe, gluten-free ingredients. Any harmless dust produced during the grinding process can simply be wiped from the hopper, spout and doser. The formula leaves no harmful residue in the grinder after the purge cycles are completed.

How often should I clean my grinder with Grindz?

For commercial grinders in regular use, a weekly cleaning cycle is a sensible starting point, though higher-volume environments may benefit from more frequent cleaning. For home grinders, once a month is generally sufficient. If you notice grind inconsistency, unusual flavours or a build-up of oily residue in the hopper, that's a good prompt to run a cleaning cycle regardless of your usual schedule.

Can Grindz be used on grinders that handle flavoured or single origin coffees?

Yes, and this is actually one of the more useful applications for Grindz. If you're switching between different coffees, particularly between flavoured coffees or very distinct single origin lots, running a Grindz cycle between them helps clear residual oils and odours from the previous coffee and prevents flavour carry-over into the next one.
