Help! How do I remove blue over tones?

[snips@home]

I've coloured my own hair for a long time now (I'm platinum blonde) I always use bleach and 6% then after with a koleston 10/8 toner always perfect. But for some silly reason I used a purple shampoo this time and I now have blue/grey streaks and I don't like it!! Please help me get rid!!

Try a clarifying shampoo it will wash out don't worry! If your hair is quiet porous from the bleach it should be out within the next couple of washes
