Tide Oxi saves the day!
A friend recently moved and the tub in the new house looked like it had NEVER been cleaned. We tried everything but the black bottom would not come clean. I had just purchased Tide Oxi on sale and thought, what the heck let me give it a try. The tub looked BRAND NEW when we were finished! I can't believe it. Not only does it work great on laundry too, but it smells nice and clean! A definite on my shopping list from now on! I noticed that it is on sale at one of the major retailers and there are coupons available out there. I would definitely recommend!
