I have a plastic container that milk went off in. It is part of a coffee machine. Any hints how to get rid of the smell would be greatly appreciated


Fill up half the container with boiling water and close with lid. So that, vapor can't go out. Wait till it the water cool down completely. Do this with couple of times.

Still you feel the smell, half-feel with water close it with lid and keep that container at your rooftop where it can have direct sunlight throughout the day. Keep it there for at least a week.

    .. and after that week, you have replaced the sour milk smell with a nice algae scent?

I use warm water and baking soda, and a soft sponge-scouring pad to wipe rub all.

Source: Myself, when cleaning stuff that had moldy milk in it.

  • After the baking soda bath, fill coffee maker with water, add1/2 cup of white vinegar and run a cycle. Rinse out and run one more cycle of plain water. That really outta do it.

The best trick I've used for protein shaker bottles that stink is to fill the container with hot water and washing up liquid and leave till cool.


Bleach is a miracle chemical for removing smells. Of course you should first wash it with dish soap as suggested in the other answers, but if the smell remains, soak it in water with just a bit of bleach added--a tablespoon per gallon of water should be enough if you soak it for a while. An aggressive bleach solution is one part bleach to nine parts water, but something much weaker is sufficient to remove smells.

If there is any metal involved, you cannot use any but the mildest bleach solution. The chlorine in bleach causes metal to rust, sometimes even forming compounds that will encourage future rust and can't be washed off.


Try rinsing the bottle with a little bit of white vinegar.

  • Hi!. Can you explain why this is a good answer? We expect answers to not just suggest solutions, but explain why they would work.
