I’d like to know of alternatives to Grindz for cleaning burr coffee grinders. I used to clean my blade grinder, by grinding stale bread. It worked well, but I don’t want to trash my burr grinder.
Any advice?
I’ve had several burr grinders over the years - conical and flat - and the best thing I can recommend is disassembly followed by a stiff (non-metal) brush.
I’ve tried literal soap an water (on my early grinders before I knew better), but honestly just a brush is the best thing I’ve found. I have also in a pinch used a super small flat head screwdriver (think for delicate electronics) to scrape out coffee impacted at the Burr’s screws.
Keep in mind that burr grinders have imperfections - and the ground coffee can “fill in” those imperfections to give a more consistent grind. Unless you are experiencing rancid or other off flavors, I’d just let things be.
