A lightening shampoo stained my acrylic bathtub. How would I remove the stain?

I had a John Freida blonde lightening shampoo in my shower and it started to leak out and I didn't notice for a few hours. Now it is stained this weird light yellow/white color. I've tried Magic Eraser and that does nothing. Any product that would remove this or any tips would be greatly appreciated.

Clorox Bleach Clearer will help you as well as the Magic Eraser.

Comet cleanser with bleach will work.
