I spilt a perfumed oil from one of those fancy air freshener diffuser bottles (with the bamboo sticks inserted) into my bathtub. I just ran water over it at the time. Now i notice it has blotchy marks and it looks like it has removed the surface of the the tub. I have not tried any products other than microfibre cloth to date.
