Sigma Mr. Bunny Brushes. I'm pleased with how well this cleans them I find it takes a bit extra soap to get out foundation and concealer from the brushes but that has been the case with baby shampoo as well.
I picked this up mainly because I liked the price, $3.00 and how small the bottle was. I don't have a lot of room in my bathroom so the smaller the bottle the more convenient it is for me. Before this I was using baby shampoo and I found that my brushes were becoming kinda dry using that. Even if I mixed it with olive oil which I don't really like to do because I find it leaves behind a residue and I just don't care for the way it feels on the brushes once they have been rinsed and dried I can still feel it, weird I know.
This brush cleaner is super convenient to use and it has little to no smell. If anything it kind of has this just plain soap smell to it but I can't smell much of anything. This really suds up nicely and gets in and cleans all the bristles with ease. I also like that this is a lot faster than having to mix up a bunch of stuff to get your brushes clean.
If your looking for a fast and affordable brush cleaner I recommend giving this one a shot for $3.00 you really can't go wrong. You can find this in store or online at places like Target or Eyes Lips Face website.
