Removing stains from bathtub and sink

Hello,

We are currently in the middle of restoring one of the bathrooms in our Colonial Revival to a mid 1910s appearance. We are getting ready to begin work on the sink and bathtub, which are in decent shape to be almost 100 years old. Both are the usual cast iron with porcelain surfaces. There are a few small stained and discolored areas on both. We were wondering what would be the best way to get these out as much as possible without damaging the porcelain. The two stains I am the most concerned with is a darkened area in the tub near the front and a rust-colored stain on the top of the sink near one of the valve openings.

I've seen people try to use chemical products like CLR or Lime Away that have ended up badly etching the porcelain, so needless to say I don't want to even try either of those. Does anyone know of any milder products or any home remedies to effectively get stains out?

Thanks!

Tom and Jada

I'll second the Barkeeper's Friend. I've seen my wife do miracles with it.

We used the "magic eraser" on our cast iron tub, with very good results. Do a test first.

I second the magic erasers! try them with Kaboom! cleaner. Worked wonders on my old porcelain tub. Mine is not cast iron though. dont know if that makes a difference.

Another vote for Barkeepers Friend. I also polish my brass and copper with it.

Magic erasers are great for cleaning the greasy chrome stovetop of my Chambers Stove. No scratches at all :D

There's also a whole peroxide process that has worked well - not the 3% stuff, but the hard stuff that they use to bleach hair - If someone remembers that thread, one of us or one of our former members used a peroxide solution to clean her/his subway tiles and tub in an old bathroom and they came out great - no scratching or etching. who the heck was it? I am thinking it was the guy who broke up with his partner then moved to san fransco - great gardener and pretty darn good renovator . . . who was it??? Maybe google the process and see if something comes up - but first - bon ami or barkeepers is no risk to your surfaces. Good luck.
