Can a coffee maker be cleaned with bleach?

Customer Review:

It’s not a good idea to clean a coffee maker with bleach. Bleach could damage your coffee maker. It is very corrosive and harsh.


If you plan on using it anyways, only add about 2 tablespoons of bleach to your water. Then run about 4 pots of just water to make sure you remove any leftover bleach.

Customer Review:

I would not use bleach in a coffee maker. It is potentially toxic even in small quantities and could cause issues with residue.

I used to use it with my beer brewing equipment and it was a challenge to remove residue even with VERY minor concentrations.


I did much better with commercial cleaners/sanitizers. Same here. I would use either commercial cleaner and descaler, of which there are lots of options, or a blend of 50/50 water and white vinegar or 50/50 water and lemon juice.

I would do it 2–3x then finish off with 1–2 runs using just clean, cold water. That should more than address any issues you are having or trying to avoid.

Customer Review:

I would say you don’t, you don’t want to end up with any traces of bleach in a coffee brewing device, A) for potential health reasons, B) Will probably leave trace notes of bleach in your next coffee.


If you need to deep clean your coffee maker there are coffee-specific non-toxic descalers and cleaners on the market, most can usually be found from coffee roasting companies or even on Amazon.

Customer Review:

Please don’t use bleach! To clean out a coffee maker run a solution of 1/2 water and 1/2 white vinegar thru the longest cycle and rinse 3 times with plain water to remove any vinegar smell.

The vinegar removes built-up oils from the coffee and any hard water residue. This works just fine for regular drip coffee makers and Keurig machines. It’s cheap and easy if a bit time-consuming.

Customer Review:

I once noticed how nasty my coffee maker had gotten, and I partially disassembled it and soaked it in a solution of bleach.

Then I washed it with dish detergent to get the bleach off of it, and then when I reassembled it, I ran some white vinegar through it.

When I got done, it was fine, but I doubt many people would go to this much trouble, given what a new one would cost.

I would not recommend bleach while using coffee makers. The coffee maker’s certain parts like brewers are sensitive and the blech might damage it both internally and externally.
