I have had luck with the liquid Bar Keepers Friend creamy cleanser and a scrubber.

Those sinks are wonderful! Think of all they’ve been through, looks like they might have been used for dyeing? Or paint clean-up? So you know anything you do with them will be just fine. (We had a concrete double-sink in our old house, we used one side for muddy or snowy boots, wet and dirty Christmas tree stands, and the like. So useful!)

Ditto on the Bar Keeper’s Friend. If it doesn’t get white enough, then I sprinkle Comet with Bleach and let it set for a bit, like 10 minutes, before scrub and rinse.

As others have suggested Bar Keeper’s Friend, a scrubby, and elbow grease, although you will probably never get them completely clean.

I would start with something like LimeAway or CLR to remove rust & hard water deposits. Rinse well. Stopper the drain and fill w/ hot water and several glugs of chlorine bleach. Let set for an hour or so. Drain. Follow up with a straight edge razor blade to remove any dried paint drips. Scrub the rims w/ BarKeepers Friend.

Then you MUST post another picture. (I'm having serious sink envy/ sink lust over here!)

Try cleaning with baking soda and a scrubby. Just make a paste with a bit of water and scrub!

Are they still plumbed? Are you keeping them plumbed or using them for storage/decor, etc.? I've had really amazing luck with this product. I first found it as a sample at Ace Hardware and couldn't believe how well it worked to remove scale and rust and hard water stains, on tile, porcelain sinks, metal and metal look plastic in the shower. My window guy uses it to remove spots from the outside of the windows where the sprinkler hits them once in a while. I've only used the cream in a jar, not the liquid in a bottle, tho. You can look for a free sample on their website, too. There is another bioclean product without a hyphen in the name so don't get that. This is non toxic, smells great, not hard on your hands, etc.

Thanks for all the suggestions. They are still plumbed and I’m dying to get them in use again! I’m pretty sure they were used for some paint clean up at some point but will post pics as I work on them!

Be very careful if you use CLR. LimeAway, or a similar product - they can pit and roughen the finish of the tubs if left too long or used excessively.

Those are great tubs! I've never seen one with legs like theirs.

I would suggest getting them RE-glazed. That will make them look like new.

Cool sinks! I see why you want to keep them. If the finish is porcelain, try baking soda before anything else suggested. Sprinkle baking soda on a wet sink surface. Let it dry then scrub with a wet yellow and green scotch brite sponge. It will take a lot of elbow grease.

I would suggest getting them RE-glazed. That will make them look like new.

For a few years, maybe. The process usually called "re-glazing" actually entails nothing more than etching the old surface and spraying a hardened paint-like acrylic over top of it. It's nothing like the original porcelain enamel, and it doesn't last. Ask anyone who's had a bathtub "re-glazed."

Just hit 'em with bleach. Scrape off any paint residue, then polish by rubbing carefully with Bon Ami. That should get them as white as they're going to get at this stage in their long lives.

Wow, major Sink Envy here. Ditto reglazing — some may do it well, but whatever was done to my sister’s bathtub became a train wreck in two years.

Are they porcelain? If so you can use a pumice stone. This article has some good tips. https://www.abbottsplumbing.com/blog/bathroom-remodeling/how-to-clean-your-bathtub/

I would start with paint stripper....if all those splotches are dried paint. Won't hurt the sink and will make your next steps of Bar Keepers friend and/or clorox easier. Great sinks!! And 3 of them!!

I recall seeing posts on the Kitchen forum years ago, about someone sending vintage sinks away to be restored. IIRC it was a true re-enameling, not something like Miracle Method.

ETA: must have been this place, the article I read says it is the only place in the country that does it, and it is not cheap www.customceramic.com

Congratulations. I am sure they come in handy for a lot of things. Good job.

You might want to give them a coat of paste wax since the finish is probably etched some. I wonder if a car wax might work? It will make clean up easier, less stains. Just apply as needed.

Forgot add. Try some non chlorine bleach. I've seen people complain that bleach leaving some kind of stain that only the non chlorine seems to help.

OH I has the jealousy!!! I hunted high and low for sinks like that before I finished the laundry room and settled for a very nice, functional SS Apron sink, but I wanted one like that!!!

I do have several old enameled fixtures - my favorite housekeeper told me to use the MrClean sponges. If you think that there is paint - I'd start with a very gentle stripper - like the soy gel or citrus strippers. Then MrClean & barkeepers friend. And remember some patina isn't bad.

They ;look wonderful!!....and 3! You could bathe triplets!

Thank you for the update, they look fantastic. I’m even more envious now lol.
