Do you have a Dirty BathTub? You can get your dirty bathtub clean with nontoxic ingredients. This cleanser removes grime from smooth surfaces without leaving any grit. Mix 1/2 cup baking soda with enough dishwashing liquid to make it the consistency of cake frosting. Wet the tub surface and add the cleanser on a sponge and scrub in circular motions. Rinse and enjoy a clean tub that you didn’t use toxic chemicals in.
