Cleaning Makeup Brushes with Castile

Cleaning Makeup Brushes with Castile

Oh how I love a good timesaving trick! Cleaning my makeup brushes with Dr. Bronner’s Pure-Castile Soap is exactly that.

Cleaning my brushes is one of those things that often falls to the bottom of my “to do” list. The only time I remember it is right when I’m putting on my makeup. Which is usually as I’m flying out the door. Which is when I don’t have time to wash the brushes.

However, if I do possibly have one more smidgen of time, the Pure-Castile Soap saves me from a wild goose chase through my cabinet trying to locate some special brush cleaning solution that I haven’t seen in far too long. Instead, I always have a bottle of Dr. Bronner’s Pure-Castile or three sitting next to my sink.

The Pure-Castile really is powerful enough to cut through dried liquid foundation crud, but still gentle enough not to cause the bristles to fall out. Clean brushes work so much better and give peace of mind that I’m not layering my face with unknown bacteria.

And it gives a lovely thrill of satisfaction that I’ve cleaned something well, taken good care of my stuff, and not spent any extra money. And that’s what GIY (Green-It-Yourself) is all about.

How to wash makeup brushes

Wet the make-up brushes in water. Add 1-2 drops Castile Soap – Organic Sugar Soap, or Sal Suds work well too! -to the bristles. Massage in gently for 10+ seconds, then rinse. Repeat as needed until water runs clear.

Using Castile Bar Soap? Wet makeup brush thoroughly. Lather soap in hands and massage gently through bristles for 10+ seconds. Rinse and air dry.

Thanks so much, Sheila! I thought about wearing pearls, but then that might be going a bit far with the 50’s theme! Then again…

Hi Lisa, chuckled when I saw your post, did all my makeup brushes last week, cleaned them in Castille Hemp Peppermint, put them in the bathroom sink and left them to soak for a while. Gosh, I couldn’t believe the colour of the water. Had I really been using these brushes on my face. Unbelievable. Some of them, I have had for ages, they look new again.

Christine says:

Excellent idea. I love having the tiny bottles all in the kitchen & bathroom.
