How to clean a humidifier

We have a very old mustard yellow humidifier, look at it, isn't it beautiful? I'll let you admire it for a while

Wasn't that just beautiful.

Anyway, it's a working devise, despite it's looks, but after whole winters use it's become limy and not clean looking from the inside. I also suspect it would work better if it's not covered in lime. So since I'm an organized and anticipatory person I desided to clean the inside of the humidifier now before I place it in deep storage.

So how to clean a humidifier, and I mean how to clean a humidifier that works with an old fashion resistor and not one of those ultrasonic humidifiers or some other gizmo that I don't understand.

The cleaning is easy and you don't actually have to do much anything. The steps are:
  1. Open your humidifier
  2. Pour in a solution of 1:1 vinegar and water so that all icky looking parts are covered
  3. Wait
  4. Wait a little longer
  5. Brush clean
  6. Rinse
Once you pour the water and vinegar solution in the humidifier the lime starts to dissolve and some bubbles will form. I just left the solution in the humidifier for about 12 hours. I was supposed to leave it only for few hours but I forgot the whole thing and went to bed because it was bed time and then finally remembered the thing on the morning. That didn't matter at all, the longer you leave it be the better. Then I brushed the resistor and the inside a bit to make sure all the lime was loose or dissolved. And rinsed the inside. Whole lot better.


  1. We have an old humidifier just like this: but even though I've tried soaking it in vinegar--and using a toothbrush to scrub, I haven't been able to get it as clean as yours. We stopped using them a couple of years ago. I just think our water is extremely hard.

    1. Last year I cleaned it the first time for most likely in years, and the vinegar dissolved all of the lime eventhough there was a thick layer of it. Water here is quite soft, maybe that does effect..? Have you tried other acids? like citric acid?

  2. I love the yellow. It is my fav. color.
