Stained Bathtub

I live in southwest Florida and just return to my home after Hurricane Irma. My house was built in '64 and has a porcelain coated cast iron tub. Upon opening the house after no power for 6 days, the tub is terribly stained. I have never seen anything like this before. It is not mold, you can't scratch it off with your fingernail. I cleaned the tub with a bleach solution, then Soft Scrub with Oxy. After that, it looked somewhat normal. 

The next day, the tub was back to the nasty stain. Any thoughts on ways to get rid of the stain?  Cleaning with a TSP solution has been suggested. Any thoughts?

Re: Stained Bathtub

Are these pictures from AFTER you cleaned, and the stains returned?

Is the tub made of fiberglass and porcelain, or is there cast iron underneath the porcelain? If the tub is older than 20 years old, it's more likely to be cast iron / steel. It looks like it had probably been repalced in the mid 1980s. Does that seem realistic?

 

Anyway, it would seem to me that the stain is being caused by something leaching from underneath the tub. Are you sure that there was no flooding? I heard that some of the homes had sewage back-up. Is there an odor in the home?

 

As for cleaning products... my first thought on cleaning this is to use CLR. If CLR (Calcium Lime and Rust remover) can't get rid of it, then nothing can. Even though I'm a big fan of SoftScrub w/ Bleach, the CLR chemically just works better.

The tub is cast iron. These photos were after "cleaning".  No on the flooding, and no odor.

Thank you for the feedback,  duly noted.

Hi Laura, try CLR then and let me know if that cleans it up. I can't remember what it looks like... but it's a green / red label on a white bottle. It's not corrosive, but chemically alters the rust stains.

Laura, I just came down to check on our condo & found the same thing. Bleach mixed with water seems to do the trick. Not sure what a good ratio is but it beat CLR, Soft Scrub, and Lime Away.

I ended up cleaning it with peroxide.  That has worked.  Bleach and other products temporarily worked, but the stain returned.  Lysol Hydrogen Peroxide Bathroom Cleaner is the winner.

Thanks for the feedback.

Glad to hear something worked. I just moved from Florida... spent the better part of 20 years living there. I still have a house there that I'm renting out... that last hurricane really hit us hard. I have roof damage, even in Fort Lauderdale.
