The cost is a penny, and the effect is like that of expensive products: wash the yellow bathtub simply
Make your own effective bathtub cleaner. You don't need to buy expensive ingredients or store-bought products—a homemade cleaning mixture will work just fine!
To create the mixture, you will need baking soda and hydrogen peroxide, Ukr.Media reports.
Mix them in such a ratio that you get a cleaning paste that is easy and convenient to apply. Take enough baking soda to clean the entire bathtub, and then gradually add the pharmacy hydrogen peroxide, mixing it with the baking soda.
Apply the paste to the entire bathtub with a sponge. Rub in a little and leave for 15-20 minutes. Then rinse with tap water.
The yellowness will disappear without much effort!
Just remember – this method is not suitable for acrylic bathtubs!
