a light acid scrub with a Mr Clean Magic Eraser should take it right off
I'm absolutely beside myself. The tub is drained. I applied brake cleaner both directly to the stain and to a bright white Mr. Clean Magic Eraser. After scrubbing, the eraser looks as it did when it came out of the package. As far as I can tell, I have not been able to remove a single molecule of this stain.The dealer is coming here Friday with polishing pads, which I imagine is a process similar to the headlight restoration mentioned earlier. The dealer also spoke to the chemical company who simply mentioned that the chemicals could turn rust-colored if poured into water with a high iron content (as suggested earlier in this thread). Other than that, they offered no information or assistance.FL Person
Here's how you remove it, if this doesn't work I'd be shocked.....fill a smaller bowl with 16-18 ounces of good warm/hot water out of the faucet, take your granular pH reducer product, measure out a good 2-3 ounce quantity, pour it into the bowl of warm water, use a spoon to stir it up good and dilute it completely...glove up, soak a mr. clean magic eraser in that solution and scrub that baby off :-)
If you think it is iron precipitated out as I mentioned earlier I like the chance of the above ph down mentioned above as working. Worth a try.

I would try "Goof Off" brand name product, it comes in a yellow can. Not Goo Gone, that isn't nearly close to the strength of Goof Off. I've always been able to get rust spots off of shells with Goof Off.
I doubt this will work, but worth a try....You might also call the Bullfrog headquarters to see what they would suggest. You could email them the picture you have, and see what they say.
