When it's cold outside, some household water-based products (liquid soaps, wet wipes) become cold to the touch as well. Since these products are used directly on the skin, their coldness may cause discomfort to the user (especially babies and the elderly).

I am wondering if there is any convenient way to warm these products at least to room temperature of 23-25°C to reduce the discomfort. I am guessing the main obstacle is water's relatively high specific capacity (at 15°C, it is approximately 4.19 J/g∙°C, according to this table, taken from this blog entry), which may also be influenced by other ingredients of the soap, but I'm not sure in which direction...

As a possible solution, I thought of putting hot water in some vessel and submerging the soap container in it. I haven't tried it yet, but I wonder how hot should the water be and how much water do I need (i.e. how deep should the container be submerged), when taking into account the volume of soap and the plastic container itself.

And there's still the issue of the wipes, which can't be submerged in water...

Repeating the question: Is there any convenient way to warm water-based products to room temperature at home?

    $\begingroup$ Find a room. Put the objects to be warmed in the room. Wait. $\endgroup$ – Curt F. Feb 22 '17 at 9:37

    $\begingroup$ Yes there is a convenient way: a microwave oven. Note, though, that it is pretty easy to overheat things to dangerous temperatures. $\endgroup$ – Ivan Neretin Feb 22 '17 at 10:09
  • $\begingroup$ I think that is one of the reasons why most people, especially infants and the elderly, prefer to have their bathroom inside a building. It has something to do with rain as well, but let's not get carried away. Btw, most babies don't use soap directly, their parents put it in their hands first and warm it that way. Try it, it works. If I understand correctly, you want to heat soap while living outdoors? If you're stuck in a blizzard in the forest, I don't want to have to use cold soap after washing my hands, yes. Maybe carry them close to your body at all times instead of your backpack? $\endgroup$ – AMT Feb 22 '17 at 12:47
