When
granite gets stained (and it often does), the stain has to be pulled out from the porous surface. With soap stains, it can be nearly impossible. However, there’s hope, as others have found ways to remove these stubborn stains. Here are some methods that have been successful.
Using Neutral pH Cleaning Products
You Will Need:
- Washing soda
- Water
- Non-alkali all purpose cleaner (ex: Simple Green Stone Cleaner)
- Soft cloths
- Soft bristled brush
Steps to Remove the Soap Stains:
- Mix water with a small amount of either non-alkali cleaner or washing soda. Non-alkali cleaners are simply neutral cleaners that will not damage the stone’s surface. Avoid any acidic cleaners as they can etch and dull the surface.
- Scrub the soap stain with the mixture. A soft bristled brush will help to work it into the grooves.
- Rinse well with clean water.
- Dry with a soft cloth and allow the area to air dry completely.
Removing Stains with Rubbing Alcohol
You Will Need:
- Rubbing alcohol
- Soft cloths
Steps to Remove the Soap Stains:
- Moisten a soft cloth with a small amount of rubbing alcohol.
- Rub the cloth over the stained area using small, circular motions.
- Add more alcohol as needed, and continue rubbing until the stain is removed.
- Once clean, dry with a clean cloth.
Using Ammonia to Remove Stains
You Will Need:
- Clear, household ammonia
- Water
- Clean cloths
- Soft bristled brush<strong
Steps to Remove the Soap Stains:
- Though ammonia has the power to cut through soap scum, it should be used sparingly. Ammonia does not have a neutral pH, and can dull the surface with frequent use. Using colored ammonias can discolor the surface.
- Mix one gallon of water with ½ cup clear ammonia.
- Moisten a soft cloth with the mixture and scrub the soap stains away.
- Rinse well with clean water.
- Dry with a soft cloth.
Additional Tips and Advice
- If the granite surface has not been sealed, consider doing so. This will lessen the chances of stains and other liquids penetrating into the porous stone and leaving marks that can be difficult, if not impossible, to remove.
- Regular cleanings will help remove any residue before it has a chance to soak into the stone. This will reduce the chance of staining as well.
- There are commercial stone cleaners that are designed to remove soap stains. One you may want to consider is MB-3 Soap Film Remover.
Due to its pH and the fat content, liquid soap, when left in contact with granite counter tops, can corrode and stain. If the area is stained, an application of baking soda or flour can draw the staining out. Just leave it in contact for a minimum of 24 hours, cover the area in plastic wrap and wipe clean with plain water the following day. Be sure to dry the area completely.
Use natural granite cleaner. I always use natural cleaner or biodegradable soap with hot water to clean the granite. Then I use a natural cleaner intended specifically for granite. A few sprays and then a quick wipe with a microfiber cloth and the streaks are gone! I can’t comment on how it works, but it does!
I use Pledge with my microfiber cloth and it removes any water marks or streaks.
I have a light tan granite countertop and someone let the liquid hand soap drip down and sit on the counter top. Now is is stained and nothing seems to remove it. Any suggestions?
Sounds too simple, but…
Just soak a sponge with water (don’t ring out) and leave sponge on the soap stain until the water evaporates. When the granite dries from where the sponge was the stain will be gone. Don’t know why it worked, but it soaked the hand soap over-spill right out of my granite counters.
Do you wet the baking soda or flour? My old soap stain is not out after 48 hours.
I tried your solution of using the wet sponge and it was a miracle. The stain just disappeared. Thank you so very much.
To remove a soap stain from granite, try soaking a sponge with water (don’t wring out) and leave the wet sponge on the soap stain until the water evaporates. When the granite dries from where the sponge was, the soap stain will be gone. Let us know if it works!
Thank you for your idea about putting a wet sponge on the soap stain and letting it dry. I bought a sponge that was extra thick and cut a hole in the center of it so I could slip it over the soap dispenser. I put it in place sopping wet and even placed something on the sponge to weigh it down to ensure every piece of the sponge made contact with the granite. I left it there to dry…several days. In fact, I did it twice. But, the soap stain is still there. Upon careful scrutiny, I noticed that the stain appears to be a little lighter, but the greasy soap ring still is about 1/4 inch out and all the way around the soap dispenser. Sadly, this did not work. Any other ideas?
Hey, my assessment might be a bit too hasty. I have tried using a wet sponge around my soap dispenser that’s built into my granite counter. At first, I didn’t think it worked, but I’ve done it three or four times and it seems to get lighter and lighter. I have nothing to lose. I’m going to keep trying it to see if I can get it completely cleaned. Thanks for the idea… but, if anyone has other ideas (like the baking soda), maybe I’ll try those between the wet sponge attempts.
Wow! It works!
After using recommended solutions (baking soda paste, applying rubbing alcohol with a Q-tip), I decided to give the wet sponge idea a whirl. I’m delighted to say, the soap ring has disappeared. Thanks so much!
The Magic of the Sponge!!
I had a soap ring on my new granite vanity. I did some research and found this site. I tried the sponge and IT WORKS!!! I am so happy that the sponge took the soap ring completely out. No chemicals; just the wet sponge on the granite and wait. It took four days for the sponge to dry, but once it did, the ring was gone. Thanks so much Marcy for the suggestion. It works like magic.
Amazing sponge!!!
Tried the alcohol…FAIL.
Used the sponge method and it worked great.
I used the dripping wet sponge on two granite countertop liquid soap stains. The stains were caused by liquid soap dispensers sitting directly on granite. Wet sponges were left on the stains until dry, with no lifting of sponges to check progress. Stains are gone! Amazingly simple. Thank you!
(This process just might be diluting the soap in the porous granite, hence essentially removing the stain.)
Sponge method works for me. Done it three times on a stubborn soap stain around the dispenser.
Lighter and lighter each time I do it. Almost all gone!!! Thanks.
I left a dish brush on the counter that was filled with Gain liquid soap. It leaked out over night all over my light colored granite. It was a mess, and I was really upset that our installers didn’t seal the granite. I used about a half cup of CVS white baby powder and plain water mixture (made thick like peanut butter). Using masking tape, I taped down plastic wrap over the stain. The tape was firm and closed off all air from getting into the stained stone area. I read that you should leave it on for 48 hours, but I couldn’t wait, so I looked after 14 hours. The stain looked like it was still there. When I arrived home from work that night, the stone had dried out and the stain was gone. I am having my installers put “life time” sealer on it tomorrow. It costs $5.00 per square foot, but it is worth it.
Sponge worked great! Pulled the stain right out! Thanks!
Marcy,
The stain is lighter, but the granite is still dark in areas that weren’t dark before because the water soaked into the granite. It has been three days since I removed the sponge. How long before the granite completely dries out? I am hoping that the granite is still wet and that is why those areas are dark.
Add me to the list of people who have had success with the sponge trick. We had not one, but two stains from soap dispensers on our brand new granite, days before it was to be sealed. Fortunately, the sponge trick worked like a charm – stains be gone!
Has anyone tried a paper towel (absorbent) or wash cloth and used heat from either a hot hair dryer or iron (on low heat setting)? Drawing the fatty soap toward the surface and then having it dry out might work well. Careful not to heat too high or long as you don’t want to bake the stain in.
We had a liquid soap ring which absorbed into the surface. Rubbing alcohol, ammonia, and soda paste were all attempted. I tried out of curiosity lacquer thinner on a folded-in-quarters paper towel and put a piece of tin foil over it to keep it from evaporating. We kept it covered for about 12 hours. Uncovered it, let the thinner evaporate, and the stain was completely gone. Now we have learned to seal the granite.
I used the sponge and wet method. After 24 hours, it worked well. No stain left. So I did not try the heat method.
I have left the lid of dishwashing liquid on the counter top. The dishwashing liquid contained ammonia and now there is a round stain on the counter top. How do I remove it?
My husband washed his hands using a Dial pump liquid shop and didn’t wipe up the excess. I noticed this a few days later, but the soap had already stained the new granite. After trying all of the above, we placed a new, very wet sponge on the stain and left it for 2 days to completely dry out. Once the sponge was dry to the touch, I lifted up the sponge and the stain was completely gone. The sponge absorbed the stain and I didn’t fret over adding more chemicals on the granite.
My entire soap dispenser infiltrated my beautiful granite countertops. My fabricator came over as he was installing a new granite countertop in my new bath. He told me to make a poultice of water, flour (any kind, bleached was ok) and perioxide, and make a paste like peanut butter/sour cream. He spooned in on all the bad areas and we covered with saran wrap, no tape, and left it there for several days. The mixture soaked out all the soap. I still have some around the soap dispenser that is tenacious, and may use the sponge method. But his mixture worked. Oh, he told me to put holes in the plastic to slowly allow air to dry up the poultice. This is my third treatment and I am starting to see my beautiful granite reappear. I have another treatment on and this time I am going to be patient and wait until every drop of the mixture dries out. He said after it’s dried, DO NOT WET IT. It’s getting better and better. When it’s all gone, I am going to have him come back and do more magic with sealing and some buffing to make them great again. But I have hope now that my granite is coming back to life. I can feel the edges where the saran wrap ends seeping out a soapy watery substance, so the poultice works like magic.
This is my first time posting on a site like this, but I needed to take the time and thank Marcy for her recommendation of the wet sponge method. Seven days ago I noticed the ring from the soap had stained my granite countertop. I wet the sponge and left it on the ring of stain. After five days I removed the sponge and let the countertop dry. The stain had lightened up significantly. I figured I would give it another try so I wet the sponge and left it on over the weekend. I just removed the sponge about a half hour ago and the stone has dried and the soap stain is gone!! It should be noted that I did try to remove the stain first by using Simple Green stone cleaner as the article suggests, but after that did not work I tried the wet sponge method and have stain free countertops again!!
I had a soap stain on our granite and I tried the corn starch. First try was putting it on the stain dry, covering it with plastic and setting a bowl on top. The stain was still there the next morning. Next try was getting the area wet, then adding corn starch, making a paste… Covered with plastic and put a bowl on top. A few hours later, the stain was completely gone.
Cornstarch worked for me! In the guest bathroom the liquid soap dripped from the dispenser on my white marble vanity top and left a pretty large stain. I tried the wet sponge, but it took too much time for too little results. So I tried the cornstarch method. I just put some water on the stain and sprinkled enough cornstarch to make a paste. Then put a folded plastic bag over it, then a large ceramic dinner plate on top. (For extra weight, I put another ceramic plate on top.) I let it sit overnight and ta-da…stain is gone!! It’s amazing! Thanks to all for sharing!
