Well....MAC uses MAC brush cleaner.


Other makeup counters would use their brush cleaner.


Any counter that sells brushes sells a brush cleaner as well.

i believe you can by a solution. also, water will work.
Each product line has their own Brush cleaners. Some brushes they can also use water. And other tools they will use alcohol.





Then there are others that they will use qtips and throw them away. This will be for lips.
It is the cleaning solution. That is what makes it disinfected.
