I know, I know. I should have taken my aligners out :( I didn't think two sips would do anything. Now my top tray is stained yellow. I've already used Retainer Brite, baking soda, whitening toothpaste, and even a bleach+soap solution. Nothing is helping. It's lightened up a bit, but it still has a yellow tint. Any tips on removing turmeric stains from plastic?On the bright side, I only have 4 more days with this aligner. I guess I can keep my mouth closed .
