Get rid of toothpaste stains
It is not uncommon to have some toothpaste drip on your shirt when you are brushing your teeth. Just make sure you rinse it off quickly because once it dries it will be a pain to remove. Titanium dioxide is a common ingredient in many brands and can stain clothes pretty badly. If you wish to remove a dried paste dot, try this.
It will not take much time. Before you put the shirt into the laundry basket, make a mix of detergent, stain remover, and water. Apply this onto the stain and make sure to rub it in. Then toss it into the washing machine the next time you do your laundry and it should come out clean as new.
