The Best Coffee Grinder Cleaning Tablets (In 2024)

As a coffee aficionado, you understand there’s nothing more refreshing than brewing your java with aromatic, freshly ground beans.

But if you’re grinding your beans from an unkempt grinder, you can compromise the quality of your brew. 

Between the hectic weekday mornings and the lazy weekends, the thought of disassembling your appliance to give it a proper clean can be daunting. 

Fortunately, there’s a solution to this: cleaning tablets. 

Cleaning tablets allow you to cleanse the machine without additional effort from your side. All you have to do is pour these agents into the grinding container and grind as you naturally would. 

The best coffee grinder tablets are:

  • Urnex Grindz
  • Caffeto Grinder Clean
  • Biocaf
  • Puro Caff Grinder
  • Urnex Supergrindz

These cleaning agents are made from natural, non-toxic ingredients that are safe for you and the environment. 

Not only are they eco-friendly, but they also offer exceptional cleaning results by freeing coffee residue in places that a cleaning brush just can’t reach. 

In this post, we’ll discuss the best coffee grinder tablets you can use to leave your appliance refreshed.

What Can I Run Through My Coffee Grinder To Clean It? 

The safest ingredients to run through your coffee grinder are cleaning tablets like Grindz. These agents are made from plant-based ingredients, making them gentle yet effective at drawing out coffee residues. 

You can use rice to clean the grinder. Provided it’s not regular rice. 

Regular rice is harder and can dull the blades or burrs. Should your grinder require repairs, the manufacturers will void the warranty if they find rice particles inside the device. 

Opt for instant rice instead. It’s parboiled, so it’s much softer and less likely to damage the electrical components of your machine. 

How Do You Clean A Coffee Grinder With Tablets 

You’d clean your coffee grinder with tablets the same way you would when grinding your beans. Most brands have instructions with recommended doses. 

But generally, you’d follow the steps below to clean your grinder.

  1. Remove any coffee beans from the grinding container.
  2. Pour 30-40g of the tablets into the container.
  3. Grind on the coarsest setting to loosen the large particles. 
  4. Turn to a fine grind to remove the remainder of the residue.
  5. Perform a sacrificial run by adding a tablespoon, or two, of coffee beans (you can also use old beans). 
  6. Grind and discard the grounds.
  7. Wipe the container with a damp cloth.

How Often To Use Coffee Grinder Tablets 

It’s best to use coffee grinder tablets once a week or fortnightly. The frequency will depend on how often you use the grinder. 

Is It OK To Use Rice To Clean A Coffee Grinder?

You can use rice to clean your coffee grinder, but we don’t recommend it. 

Rice tends to clump up and can damage some electrical components of your grinder. If you decide to use rice, opt for instant rice. It’s partially cooked, so it’ll be less abrasive on your appliance. 

If you want to extend and enhance the longevity of your device but are skeptical about using rice, we’ve got you covered. 

Below’s a guide to the best coffee grinder cleaning tablets on the market.
