Stain Devils #9 (1.7 Fl Oz), Targeted Spot Cleaner for Rust & Perspiration Stains, Safe on Skin & Washable Fabrics

Okay. It seems a bit pricey, but trust me when I say a little of this product goes a long way. I first used it this summer, and dabbed just a little on some sunscreen and rust stains on a pair of white linen shorts. I let it sit for an hour, per the instructions on the bottle. I laundered the shorts on a delicate cycle, hung them to dry, and was delighted to see the stains were gone. Fast forward to this week, when disaster struck - we had a water outage in my building while I was doing laundry, which included my beautiful white Wolford bodysuit. I stopped the machine, and restarted it when the water was restored.... and found, when I took my laundry out, that a lot of copper had been come in with the water. My beautiful bodysuit was now a dingy orange-y brown. With the garment still damp, I put on rubber gloves, stoppered up the sink, and poured the bottle slowly over the blouse. I didn't think there would be enough product, but I would pour a little, and squeeze it gently through the garment. Then more product, then careful squeezing through the top, trying to make sure I got the stain remover everywhere on my blouse. I was very excited to see the blouse looking cleaner within ten minutes. I let it sit in the sink for an hour - but I went back at 8-10 minute intervals, to turn the garment over (sopping up the little bit of liquid at the bottom of the sink, and making sure to gently work the product through the blouse). At the end of an hour, my blouse was sparkling white again. I rinsed the blouse in several sinkfuls of water, then I hand-washed it (as I normally do), squeezing gentle soap through it. I rinsed it several times, and let it dry on a flat rack. And I got my blouse back! I AM SO HAPPY WITH THIS PRODUCT. It isn't cheap, but it WORKS. Worth every penny. You don't need the garment to be soaking wet and dripping. You just need to put some gloves on, apply enough of the liquid to cover the stain, and then gently work the product throughout the stain you're trying to lift. Please note that this product is very liquid, like a water-consistency, and will pour out of the bottle fast.

I ordered this to use on sunscreen stains from avobenzone sunscreen that showed up after washing a white shirt. The stain disappeared after 10-15 minutes. I have well water that is rust heavy. The stain came back after washing again but everytime I used carbona #9 the stain would get lighter and lighter until it stopped coming back all together.

Doesn’t work.

I tried everything to take some rust stains of my clothes and nothing worked. Then I tried this product, one wash later and the stains were gone. I never write reviews but this product saved me from having to replace a whole outfit.

Got this to try and fix a favorite t-shirt’s crusted armpits from deodorant build up. Needed some serious scrubbing power but it worked really well.

Nothing exceptional here. I was hoping this would remove some more stubborn laundry stains but no joy. Yes I followed the directions. Yes I tried it on several different pieces of clothing and fabrics. I'm wouldn't count on it to get rid of that stubborn set in stain.

It’s good , but needs to be a larger bottle.

I recently learned that a chemical in sunscreen can react with iron or copper in water—like in well water—to create rusty stains on clothing. I had tried everything to remove these burnt orange stains from my shirt and bathing suit. I used multiple stain removers, soaked the clothes in vinegar, washed them repeatedly with various stain-fighting products—nothing worked. I even had to dry the clothes because I had a flight the next day, and I was ready to throw them out. As a last resort, I ordered this product, though I didn’t have high expectations. When it arrived, I was a bit disappointed by how small it was. But I dabbed it onto the stains, let it sit for an hour, and to my surprise, the stains vanished completely! I wish I had taken a before picture to show the dramatic difference, especially on the collar, which was intensely orange. This product saved my clothes—I couldn’t be happier!

This product didn’t work at all. It’s overpriced (100 SAR for only 50 ml) and was a complete waste of money.

Managed to remove sunscreen stains from white clothing.

This does not work at all -- as in, it literally does nothing. I may as well have splashed water on the stain for all the good this did. And you have to use it undiluted (according to the instructions) so I had to use the whole bottle on one stain. A total scam -- do not buy.

j’avais de la rouille sur un jeans pale et tout à partie mais je ne l’avais pas mis dans la sécheuse avant de la nettoyer avec le produit. je suis bien heureuse de mon achat même si le contenant es petit

I was so surprised to find a product on the market that works! I had rust stains on my white pants, and they have sat ruined in my cupboard for a few months before I tried this 2 washes and they are free from all the stains Super impressed
