I'd like to know if this is used in a bathtub, does it make it slippery? I have also used the astonish product (not on bathtub) and it works well for what I used it for. My current favorite, although contains chemicals, is kaboom because it really works wonders with my old stainless sink. Don't recommend kaboom for bathtub because, with my experience, made it very slippery Think I may order while they have different scents and give it a try.
