All I use is a cup of lukewarm water, and some kind of liquid soap. So for example right here in using Cussons imperial leather but I’m pretty sure you can use anything!
For some reason I really like doing this, I just like watching all of the product come off of the brush into your hand. It’s weird but it’s a fact.
After that, I rinse off my brush and set them on a towel, I repeat that with every single brush I have.
Bonus – how I clean my beauty blender
All I do is I get hot water and add it to a cup with my beauty blender. I add my liquid soap and squeeze all of the access foundation out of my beauty blender.
Once again, clearly I’m not a professional haha. I might be doing things completely wrong but I don’t really care, it’s how I’ve always done things!
