One might wonder why do one needs a grinder cleaning tablet, because coffee beans leaves oil residue behind in the grinding process. After a while oil will become rancid and gives an off tasing flavor if not cleaned properly. So this is where this tablet comes in, it's really convenient and painless option.

I primarily use these cleaning tablets when transitioning to a new batch of coffee. While they claim to remove oils and particles from the burrs without the need for disassembly, I still suggest taking the grinder apart to clean off the ground tablet residue and brush the burrs. Also, I would recommend running a small amount of beans afterward to ensure any remaining residue is cleared out.

These coffee bean style tablets were easy and great to use. Bonus for being bio friendly. Just grind them, then brush it clean and run some beans through to flush the rest of it out. My year old Opus was oil and residue free. Why did I wait so long to buy these? Don't make the same mistake I did. Essential.

Works like a charm. Happy to add this to my cleaning routine.

If you’ve invested in a decent electric grinder, this is a must have solution to clean it. My grinder is as good as new now.
