How do you clean a liquor flask?

Answered by James Kissner

Cleaning a liquor flask is actually quite simple. I’ve had to clean mine a few times, and I’ve found a method that works really well. Here’s how I do it:

1. First, I gather all the necessary materials. You’ll need vinegar or lemon juice, hot water, a small brush or sponge, and a dish towel.

2. Next, I remove the lid from the flask and pour out any remaining alcohol. I make sure to do this over the sink to avoid any spills.

3. Then, I fill the flask about halfway with either vinegar or lemon juice. Both of these options work well as natural cleaners and help to remove any lingering odors.

4. After that, I heat some water until it’s hot but not boiling. I fill the rest of the flask with the hot water, making sure to leave a little bit of space at the top so it doesn’t overflow when I shake it.

5. Once the flask is filled, I securely screw the lid back on and give it a good shake. This helps to agitate the mixture and loosen any residue or stains inside the flask.

6. I let the flask sit for about five minutes, allowing the vinegar or lemon juice to work its magic. During this time, I make sure to keep the flask upright to avoid any leaks.

7. After the five minutes are up, I remove the lid and empty the contents of the flask into the sink. I’m always amazed at how much dirt and grime the vinegar or lemon juice has managed to remove.

8. Now it’s time to give the flask a thorough rinse. I use hot water to flush out any remaining residue, making sure to rinse both the inside and outside of the flask.

9. To clean the inside of the flask more effectively, I use a small brush or sponge. I gently scrub the walls and bottom of the flask to remove any stubborn stains or buildup.

10. Once I’m satisfied with the cleanliness of the flask, I give it one final rinse with hot water to remove any soapy residue from the brush or sponge.

11. Lastly, I dry the flask with a clean dish towel. I make sure to dry both the inside and outside thoroughly to prevent any water spots or mold from forming.

And there you have it! A clean and fresh liquor flask ready to be used again. I hope this method works as well for you as it does for me. Cheers!
