You know what’s a frustrating problem to any soap maker? Soda ash. I tried all the tricks before I learned how to remove soda ash from my handmade soaps in a way that was easy and effective.

From shaving it off the outside layer, steaming it, spraying it with alcohol. Nothing really worked well in my opinion. Some recommend preventative measures by spraying the freshly poured soap with 99% isopropyl alcohol but my mold has individual cavities and the soda ash also forms after coming out of the molds on the 5 sides where the mold covered the bars so that’s not really going to work.

Soda ash also seems to be a seasonal problem for me, though I don’t understand why that would be… it always give me the most problems with the soap I make in the fall and winter.

Some types of soap seem to be more prone to it than others. I’ve had it on my Homesteader’s Tallow Soap on occasion, but have yet to see it pop up on my Gardener’s Super Scrub Soap. Bizarre. It really drives me up the wall when I make a pretty swirly topped Flower Infused Milk Soaps and all the lovely peaks and valleys are ash dusted like snow on a mountain range. Super frustrating!

Thankfully, soda ash is perfectly harmless and is only a cosmetic problem. (Pun not intended.) If I were making soap just for personal use, I wouldn’t worry about it at all, but if you would like to give your bars away as a gift, then you’re going to want them to be beautiful I’m sure.

So when my bars start looking like they’ve got white mold, what do I do?

How to Remove Soda Ash from Homemade Soap

*Consider wearing gloves so you don’t leave any fingerprints.

1.) Use a spray bottle of water set to mist and finely spritz your bar of soap with the water.

2.) Use a dry, lint-free rag to polish the soda ash away.

3.) Brush the rag across the surface of the soap in one direction.

4.) Blow dry each side that you need to clean until it is fully dry before handling with your fingers.

Couldn’t be any easier, could it? (Unless it wasn’t on there to begin with that is.)
