Review on Pack of 2 EcoTools Makeup Brush Cleaner Cleansing Shampoo, 6 oz (12 Fl Oz in total) - Varying Packaging by Mary Medema

I used this shampoo on three of my favorite brushes and the bristles turned blue. I figured they might look different when dry so I let them dry overnight. They were still blue in the morning so I took the big brush and washed them again thinking it might be the result of some other chemical based on the many 5 star reviews and the fact that I read the reviews couldn't find any mention of it. Well, on the second wash it went from partially blue to solid blue. So my two favorite brushes are now blue. Needless to say, I won't be using it a third time. I will send it back immediately. I have no idea why the brushes turned blue. I will never buy again and will tell everyone I know who cleans brushes.
