Well yes, vinegar does work. You have to run it part way through, stop the machine for a while, then turn it on so the vin can continue on through. Then run one or two rounds of clear water. I've cleaned coffeemakers this way for years and never had a problem.

I've used baking soda. i read it lord knows where, but i put a little bit in with some water and run the machine. then i run it again a few times with clean water to clean it out. Seems to work ok for me. I just got a 'nice' coffee machine, and that was also actually in the instruction manual to do before using the first time.

Seem so to work well for me :)

I do vinegar. I've owned many coffeemakers and always use the same method. Fill it at least halfway with vinegar and then run it. Whole kitchen stinks.

Then I just keep running full pots of water through it until I can stick my nose into the water reservoir and not smell vinegar, however many rinsings that it takes. Might take two. Might take five or six. Wiping interior of the top cover with paper towels to get the vinegar condensation in between rinsings.

I also remove whatever parts that hold the coffee filter, etc that can be removed and use a sponge 'scrubber' to make sure all of the residue is gone out of the 'grooves'. I do not find that merely washing parts in the dishwasher sufficient to get rid of that greasy residue.

Works for me.

My Cuisinart coffee maker has a filter that I noticed by accident a while back. Changing the filter has helped with the taste of the coffee. I'm one of those people who assumes I know how to use an appliance so I didn't read the manual that came with it.
