A paste of baking soda and water?

I am reading on the internet after a quick search. Some people have removed stains with Bar Keeps Friend, a Magic Eraser or 409. I don't know what type of Quartz you have. These are just suggestions that have worked for other people. I would call the manufacturer and get their advice and/or search the Internet.

I have Caesarstone. When it was installed they told me not to use anything with ammonia in it (window cleaner).

No abrasives! It can dull the finish! I got a new countertop because of Barkeeper's Friend applied by the installer.

Look at your Use and Care info online. Cambria won't let you use anything, but Caesarstone allows Soft Scrub Gel with Bleach. That's what I use, but since you're not supposed to leave bleach on quartz (it can yellow it), make sure you rinse thoroughly.

Hey, that looks just like my counter! (I just enlarged the photo.)

Test anything new on a piece of scrap (I hope you have one!) or an out-of-the-way, poorly lit spot. I use Bar Keeper's Friend for rust spots, but my counters are metal so it doesn't hurt them.

I called and asked - they said to use soft scrub with bleach and elbow grease, and after a few minutes of scrubbing that seems to have worked (this was pental quartz btw)

Is it Botticino? That's what I have. Glad the Soft Scrub worked!

Great - I use Soft Scrub too (Ceasarstone).

Yes to the baking soda/lemon juice combo + a little elbow grease

For my now replaced silgranite white sink which stained awfully, we used mineral oil and baking soda powdered soap like bar keepers. Also works great for oil baked on stainless cookie sheets etc.

I just tried the baking soda and lemon juice- it worked like magic!! I'm glad I peeked on here!

After testing this product on a sample to make sure it did not damage my quartz, I used this on my rust stains and they disappeared like magic. I just dabbed it on the stain, let it sit for an hour and rinsed it off. https://www.amazon.com/Davis-Instruments-Fiberglass-Remover-16-Ounce/dp/B001446K4G/ref=asc_df_B001446K4G/?tag=hyprod-20&linkCode=df0&hvadid=312151608179&hvpos=1o1&hvnetw=g&hvrand=3453028626857896826&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9012131&hvtargid=pla-569632687188&psc=1

Baking soda and lemon juice rubbed in with a paper towel did the trick. It took several rounds, but it worked.

Thank you for these comments and easy tricks. Also got rust stains on my white quartz countertop. Tried the baking soda and lime, scrubbed a little and it got off right away. I would just recommended not even using a scrub pad. The spot where I rubbed not even long does appear a bit more dulled out (changed the shade of white a bit and depending on the light angle). So very good trick just rub softly.

Teaspoon of baking soda combined with 2 - 3 drops of lemon.

It worked so well I was able to get the rust stain off using my finger in a matter of seconds. After it wiped off I washed the counter with soap and water with a soft cloth. No elbow grease was required.

After I shed a few tears finding rust on my Cambria countertops, thankfully I saw these posts. Baking soda and lemon worked perfectly and in a matter of minutes ! Thank you !!

I know this is old, but a soft pencil eraser (preferably white) works as well. Just have to lightly scrub the area with a magic eraser to get the residue off when you’re done. Try it!!

Easy, just use Vim (cream). Remove quartz stain in a sec.

The eraser worked like a charm! Thanks for the suggestion!!!

Moved in a new house a week ago. Put a cast iron Dutch oven on the counter for about an hour And when I moved the cast iron there was a perfect rust stain circle. Uggg.

initially scrubbed most of it off using simple green cleaner and elbow grease. Then coated the counter with simple green for about an hour. Then refreshed simple green on the counter and coated with baking soda. With very little effort the stain was gone.

so I recommend baking soda with simple green or use lemon juice. Either will work on most any kind of stone

like material.

I did the same thing as the original poster. Put an Iron skillet that was wet on quartz. it left a dark ring of rust. I tried bleach spray and let it sit for 2 min. It didn’t work. I jumped online and found this post.

We used baking soda with lemon juice, and elbow grease. Worked perfectl! We let it sit for approx. 4 min then scrubbed gently. Thanks for the advice all.

I tried many of these ideas but nothing worked on rust stains on a bathroom granite or quartz (waiting on the previous owner to tell me the material). Looks like it is from metal containers left on the counter probably with water underneath. Anyone ever has success with removing these stains when the baking soda didn't work?

Tricia:

Look under your countertops please. Do you see a logo or printing? If so, your top is very likely engineered stone. If you post a picture I may be able to tell. Either way, I'd try some of this.

Thx...it is quartz. Does your product work on that?

Has anyone had a problem where they’ve managed to remove the rust, but can see a dark patch (almost like a shadow) where the rust once was? It almost looks like the white in our quartz has disappeared in a circular line where the rust was.

We just had white w/ grey lines quartz installed and so disappointed. I think it is fake quartz. From day 1 we keep seeing little Yount spots, literally everywhere. Now a metal wster bottle was near faucet.. has left a ring. Hell. I’m ready to get new counters. Stains are everywhere. I have Bar Keepers and a spray called Stone Care. Help

OMG THANK YOU for the baking soda/lemon juice tip! New quartz countertops (that we have been saving to buy for years) went in Saturday, Sunday was Superbowl. Used a little crockpot for a dip (that I haven't used in a year) and when I went to clean up last night, the stupid thing must have had condensation build up inside and it leaked from the bottom and it left a rusty wet stain on my new counter!!! I've never had that happen with a Crock-Pot and I was sick to my stomach when I saw it. The countertops are a medium gray so it was very obvious. I tried water and a gentle cleaner and it didn't work. I was afraid to try CLR or something more serious because I thought it might ruin the surface. The baking soda / lemon did the trick and didn't do any damage to the surface. I can breathe again! Thank you!

Hydrogen peroxide works for rust.

Just used baking soda and lime juice and it was instant!!!!

Note that lime juice is about 50% more acidic than lemon juice. So, if you are concerned about the sheen of your countertops stick with lemon juice and rinse well after.

several rounds of baking soda and lemon juice worked! Thank you!!!

I couldn’t find it to take a picture of the spot!

Thanks for the lemon juice + baking soda tip!! Perfect.

The eraser worked on the rust stain! Thank you Jennifer C.

Wish I saw this before I used Brillo.....Now the area;s finish is rubbed off...anything to remedy?

It might not be the finish that is damaged. The Brillo may have left a cloudy layer. Use a good, non-abrasive cleaning product (even just gentle dish soap and clean water). Scrub hard (but with a non-abrasive towel or sponge). Rinse very well after - even dish soap residue will dry cloudy on the surface. Odds are this will fix the issue. Try baking soda and water as well if you need to. You can get a more aggressive cleaner (Caeserstone recommends Soft Scrub gel cleaner with bleach). Important though that you never use an abrasive sponge (not even the scratchy side of a plastic sponge).

If that fails, you can try polishers such as Quartz Renew or Granite Gold Quartz Brite. They don't actually polish though, they just give a temporary shine. Only a true mechanical polish will repair it if it is actually damaged. It would be something best left to the professionals (you risk overheating when you polish mechanically, which would cause other issues).

Thanks here it is....same advice after seeing it?

Quartz Renew is certainly a polishing system; not topical. That's what it's going to take to fix that. Tenax Quartz Toner is topical. Fine product, but not for this.
