I have an old cast iron tub. It is probably over 60 years old. I like the tub but it has always been very hard to keep clean. There seemed to be very old stains which were in the tub that I just could not get out. I have used more cleaners than I can count and scrubbed this tub with all my might and still could not get it clean. Most products would get the surface stains but it did not get deep into the tub and get the tougher stains out.
I finally purchased Scrubbing Bubbles and could not believe the results. It was very easy to use and required very little scrubbing. The product did most of the work! I just sprayed onto the surface and allowed it to set for a few minutes to get into the surface. I then used a scrubbing brush but had to only scrub lightly. Afterward, I rinsed the tub. As I saw the water going down the drain, I could not believe the amount of dirt and grime that was coming off. My tub has never looked so clean.
I also liked that it was antibacterial. Scrubbing Bubbles has a very nice fresh scent that is not over powering like some other products that I have used.
