I love a clean bathtub and this totally does it :) This also works if you got something sticky or greasy on your oven top and an all purpose cleanser isn't working.
CREAMY SOFT SCRUBBER
1/2 Cup baking soda
Make texture like frosting and scoop onto sponge, and scrub surface! You have to make this one batch at a time, or else add a vegetable glycerin and then put in a glass container that shuts to save for another day.
