Empty the grounds container too. Quickly wipe it down with a dry cloth to catch any coffee dust.

Step 4 – If you have a burr grinder you can grind rice

Along the way, the rice will acquire oily material. Then, flush through a couple of batches of cheap coffee beans to clean out the rice dust. Actually, don’t skip to this bit else your next cappuccino will taste of rice.

Cleaning tips for tough heavy lifting
A little cleaning ain’t cutting it sometimes. If you haven’t cleaned out your grinder in months, you may well require a more vigorous strategy.Instead, you should use dedicated cleaning tablets formulated, particularly for coffee grinders that dissolve through oily residue. They’re like a stronger version of the rice method, where the tablets absorb oils as they go through the burrs. They’re available at almost any kitchen store or online.
For really nasty grime, some folks remove the burrs altogether and soak them in warm soapy water. It will only work with completely removable burr sets, so be sure to consult your manual before attempting this. To avoid rust, dry the burrs completely before putting them back.
Do with a Peaky grinder full of smells
A musty odor is typically the result of moisture that’s trapped somewhere, or old oils that have gone rancid. This is usually resolved by passing the rice through the grinder multiple times. If the odour persists, you can try leaving the disassembled components out in the fresh air for a few hours.
Odour absorbers such as baking soda could also be used. After that, just leave an open container beside the grinder parts while they dry and the smell is supposed to go away within a day.
Popular Mistakes People Make While Cleaning
Cleaning mistakes are common even among conscientious coffee lovers. Here are a few to avoid.One of the things you train your mind against is to not use water directly on the burrs. It can lead to rusting, leaving the grinder ineffective for good. Stay with a dry brush and rice with the burrs themselves.Another common mistake is to skip clearing the rice. If you just used some rice and you don’t run coffee through afterwards, your next cup is gonna taste a little bit starchy. First, always flush the grinder with a bit of cheap coffee.
