I add this ingredient to baking soda and I get a powerful stain remover!

Polishing silverware
With toothpaste, you can also polish your matte silverware. All you have to do is put a dab of toothpaste on a cotton pad and then wipe it on the matte surfaces. Leave it on for a few moments and then rinse with cold water. This way, they will shine as if they were new.
Black marks on shoes

In this case, all you have to do is moisten an old toothbrush and add a little toothpaste to the bristles. Then rub on the stains of the shoes in order to use the abrasive action of the product. Once this cleaning work is finished, rinse and after that your shoes will be perfectly clean.
Clean the joints between the tiles
Whitening the joints between the tiles is very easy. Just add a little toothpaste to an old toothbrush that no longer uses it and go and scrub vigorously. I recommend that you use this method by cleaning a small area at a time and obviously adding toothpaste from time to time. You can also clean the yellowed or moldy corners of the shower. Then, you just have to rinse and dry carefully.
