Mascara: Get yourself a pre-wash stain fighter like Shout and apply to the stain using the brush that comes with the pre-wash. Let it sit for about 10-15 minutes, then rinse with hot water. Launder the garment immediately either by hand or in the machine (whichever is most convenient for you).
ADA accepted bleaching gels use a 10 percent concentration of carbamide peroxide. When used in a water-based solution, carbamide peroxide breaks down into hydrogen peroxide, which is the active whitening ingredient. Have your dentist show you how to apply the gel to your tray. Brush your teeth before applying. You only need to wear the tray for a few hours during the day or overnight. Your dentist may recommend using the mouth tray for about two weeks to get whiter teeth.
