Customer review from the Amazon Vine Programme (What's this?)
I wear only white shirts for work, since I'm a practical kind of guy and I want to be able to get as much use out of each shirt without the colour fading - hence sticking to white shirts. However, this only works if the shirts stay white instead of going '100 Wash Grey' and Vanish is the only product I've found that consistently keeps my shirts looking presentable. I tend to go through my entire collection of shirts before I realise I need to do a white wash, then cramming all of them into the washing machine. Just adding a scoop of this in the machine's drawer always does the job admirably. Even collars and under-arms come out white. There are cheaper alternates out there, but not better ones.
