Mixing toothpaste and baking soda is, in fact, a very popular and effective home trick for certain cleaning tasks. The combination of the gentle abrasive power of both ingredients can be a simple solution for removing stains and adding shine.

How this mixture works
Baking Soda: Acts as a natural exfoliant, helping to remove dirt and stains without scratching. It’s also an excellent deodorant.
Toothpaste: Contains mild abrasives, detergents (such as sodium lauryl sulfate, which creates foam), and polishing agents, which help lift dirt and restore shine.
Where you can use it (and where you shouldn’t)
This mixture is ideal for surfaces that resist gentle scrubbing. However, it’s essential to avoid using it on delicate surfaces such as marble, natural stone, varnished wood, or any non-stick surface, as the abrasives can cause damage.

You can use it for:

Cleaning tiles and grout: The mixture is perfect for removing mold and darkening from tile grout in the bathroom and kitchen.
Removing sink stains: It works well for cleaning stainless steel or ceramic sinks, removing coffee, tea, or food stains.

Polishing metal: It can be used to polish chrome faucets, restoring their lost shine. Test on a small, inconspicuous area first.
Cleaning white sneaker soles: This is one of its most popular uses. Toothpaste removes dirt and leaves the soles looking like new.
How to prepare the mixture
The recipe is very simple.

Ingredients: A small amount of white toothpaste (gel or colored toothpaste don’t work as well), baking soda, and a little water (if necessary).
Instructions: Mix equal parts toothpaste and baking soda in a bowl. If the mixture is too dry, add a few drops of water to create a thick paste. Apply with an old toothbrush or a soft cloth. Scrub gently, then rinse with water and dry the surface.
Remember to prepare only the amount you need for immediate use, as the mixture doesn’t keep well.
