Sometimes the wonderful world of chemistry can be frustrating.
I love it when it works its magic to make oils and lye turn into soap.
Not so much when the soap ends up with soda ash on the surface. Ash is sodium carbonate, the harmless product of the reaction between sodium hydroxide and air.
It can look nice sometimes. Like on the tops of these bars it looks like frosting.
But I hate when it happens on a soap that I want to be able to see the surface.
Exhibit A:
Great swirl, huh? If only it didn’t look like it needed a good dusting. It’s batches like this that I can’t leave well enough alone.
And now I’ve discovered what may be the easiest way to get rid of the ash: steam!
When I first say this on some YouTube videos, it looked like magic. Then I tried it myself. And you know what? It IS magic. I now believe in magic.
All you need is some source of steam. I like to use my kettle because I get a concentrated stream of steam that way. But you could just use a saucepan filled with water.
Or maybe one of these?
Just take your ashy soap bars, like these
and hold it over the rising steam. Careful! Steam is very hot so protect your fingers.
The ash just disappears. It really does! Then it’s just a matter of waiting for the surface to dry.
Gorgeous.
And those swirly bars? Oh, yeah… magic.
Do you steam off ash? Or do you use a different technique?
Fabulous solution! I have a travel steam iron. I will try it next time this happens.
Oh, that sounds perfect! With something handheld like that you can lay out your bars and just wave the steam over them. I bet you’ll be done in a jiffy!
We keep recommending this technique – now we can send people here to see how it works! Thanks!
That’s great! I was so impressed with the results that I knew I had to take before and after shots, if only to prove the magic. 😉
Beautiful soaps, Ruth! I love those swirls. I find steaming to be the easiest way to get rid of ash, too. It’s especially great for bars with textured tops!
Thanks, Jenny! Yes, it’s great for that. I used to use a spray of alcohol, but could never do it with the wavy tops. This method works with any surface.
I’ll have to try this with a kettle or the steamer. I tried steaming my soaps once with my Rowenta iron but it didn’t seem to help much. I wonder if it had something to do with the water- I can only use mineral water with it. I have been cleaning my ashy bars by scrubbing with nylon and a little water. Your technique seems easier.
Yes, JV, I think that having a strong, steady stream of steam really helps. It will be much easier (and more gentle) than scrubbing each one.
I always spray the exposed top with 90% rubbing alcohol and then cover the mold tightly right after I pour. Upon unmolding, I rarely get ash anymore.
I do that sometimes, too, Rene. But I was finding that it didn’t always work for me. So I’m happy to have another method for those times.
I turn my microwave into a steamer. I pour hot water into a pan and place a cooling rack full of soap bars over it. I shut the door and in about 10 min- no ash! I do not turn on the microwave at all- I just use it as an airtight box.
That’s so clever, April! Thanks for the great idea.
thanks for this tip — will be trying it soon.
Merci beaucoup, je vais terster
Bonne journée
