I've always just used my shampoo.

I run them through the dishwasher.

I just use soap and water.

Dawn dishwashing liquid. If it's safe enough to use on wildlife covered in oil it's safe enough for my brushes!

I use Dawn, too, and sometimes baby shampoo (I already have it on hand for mascara removal).

I use shampoo or a foaming facial cleanser if shampoo isn't handy.

That's interesting about Cetaphil although I have never used it. Makes you wonder if it is really removing any makeup doesn't it?

I spritz on a brush cleaner and rub them around on a terry washcloth.

I used cetaphil for years - upon the recommendation of my dermatologist. Just recently changed to CeraVe because my skin is drier. May need to switch back to cetaphil for warm weather. I always use witch-hazel toner after cleansing, and I can attest that the cetaphil leaves little residue. However, it is a mild cleanser and you can get alot of makeup built up on sponges/in brushes. On my brushes/sponges, I use soap and water or shampoo.

Next time I'm going to try Dawn or shampoo and see if it pulls the make up out. I was sorta surprised the Cetaphil didn't do much.

I use shampoo - it really gets rid of the built up makeup residue.

I use Cetaphil as a gentle cleanser for my face and use a washcloth during rinsing to make sure all makeup is removed. Other cleansers cause irritation. It's not what I would use to deep clean my brushes but seems to work well for my skin.
