How to tone hair

I bleached my hair twice in one day, and it's orange. (I know that's bad but my hair as been able to withstand ALOT of torture.) I also wouldn't care if I had to cut it off.

Anyways, it's platinum on the roots and orange for the rest of it. I'm going to wait at least a month or two to bleach it again. (I'm not going to a hair salon, the ones near me have messed up everytime) and are outrageously expensive. I heard a toner can lift some of the orange?

What's the best products? I read somewhere that mixing blue dye and conditioner works, but that doesn't really make sense. I honestly don't even know what a toner is since ive never run into this problem.

Thanks in advance
