Hi you! :)
I use plain old antibacterial soap, and it can be from any brand, just as long as it says 'antibacterial' on the bottle. This is important since an antibacterial soap will really get rid of any bacteria that is sitting on the bristles. This method does not leave the bristles dry, and my brushes really look and actually are squeaky clean! I simply pour a tiny amount of soap on my hand, wet it a little, and go back and forth on my hand with the brush and rinse and squeeze out all of the soapy water. Make sure you never get any water above the ferrule of your brush (the metallic part) since getting some in there might loosen the glue that holds the bristles together and cause them to fall. I recommend deep cleaning your brushes at least once a week.
For spot cleaning:
I use isopropyl (rubbing) alcohol, which kills bacteria instantly. I buy a big bottle and transfer some into a travel size spray bottle, spray some on a paper towel, and go back and forth on it with my brush and repeat the process for all of my brushes until all the color has transferred onto the paper towel. I spot clean my brushes before every use, just to be on the safe side since I am prone to breakouts and try my best to avoid spreading unwanted bacteria
back on my face.
Best part? You can get both for under $5 at the drugstore or at the grocery store. Now that's a bargain! :)
