The KIT Makeup Brush Cleanser is a liquid cleanser in a squirt bottle.  You spray the product onto your dirty brushes, massage the product through, and rinse the brush under water.

This absolutely did clean my makeup brushes.  I could see how much cleaner they were after finishing the cleaning process.  However, I do have a few issues with it:

- it tells you to rub the product through to "form a lather" -- I found it next to impossible to form any sort of lather.

- very little product comes out with each squirt, so it seemed like I was having to squirt several times for each brush (larger ones, in particular).

- I'm not sure that this process was really any faster or more effective than my normal way of washing my brushes in the sink.

The third point is probably my biggest gripe.  I was hoping this would cut down on the amount of time it would take to clean my brushes, but I was still having to stand at the sink for a long time squirting, massaging, rinsing, squeezing out excess water, and laying flat to dry.

Although this definitely did its job, I'm not sure that I would pay $10.49 for another bottle of this when I achieved the same results as I typically so with mild soap and water.
