Frequently Asked Questions

  1. Can Carbona® Stain Devils® be used in the washing machine?

    Stain Devils are not a pre-wash. For best results, you need to treat each stain completely, before laundering and drying.

  2. Can I use Carbona® Stain Devils® on carpeting?

    Carbona® Stain Devils® have not been tested for use on carpeting. However, we have had many consumers use them on their carpeting with great success. Doing so is at your own discretion.

  3. Will the formula for ink remove permanent ink?

    Permanent ink is permanent. Unfortunately, the stain is there forever.

  4. Why do I need to put a cloth under the stain?

    Stains can spread while being treated, so you need somewhere for the stain to go when you remove it from the material you are treating.

  5. What if I can't put a cloth behind the stain or put the stained area in a bowl?

    For best results we recommend that you follow the directions on the bottle. However, as a last resort, you may try dabbing the material with a white cloth soaked with the formula then pat dry. Repeating process as necessary until stain is gone.

  6. Why do I need to flush the stain with hot water after treating it with Carbona® Stain Devils®?

    You need to rinse out the formula because if you let the stained area dry out without rinsing, the stain can reappear. The hotter the water, the faster the stain removal process.

  7. Will Carbona® Stain Devils® also remove the odor (like perspiration)?

    Carbona® Stain Devils® are formulated for removing stains. Follow with regular laundering to remove odors.

    No two stains are the same, so an all-purpose stain remover isn’t the answer to treating them. That’s why we created Carbona® Stain Devils® – 9 powerful formulas that treat specific stains. Stain Devils are safe and effective on washable and water-safe fabrics, excluding silk, acetate, carpeting, or upholstery. Every formula is dermatologically tested to be safe for your hands and environmentally friendly for disposal.

    Look for the little yellow bottles of Carbona® Stain Devils® in the laundry section of your store. View all of the Stain Devils here.

  1. Use the formula that’s right for your stain. Follow the directions.

  2. Because Stain Devils are individually formulated, stain removal instructions may change from formula to formula. Follow the directions printed on the label of the bottle you are using.

  3. Some are instant, some aren’t. Be patient. While the appropriate Stain Devils formula should completely remove your stain, the time required may vary from immediately to several minutes or more.

  4. Combination stains. This can make stain removal a bit more complicated and may require more than one Stain Devils formula to remove it completely. But if you value your garment, it’s worth the extra time.

  5. Directions

    Spot remover for washable and dry clean only fabrics.

    Just 3 easy steps to stain removal:

    1. Before treating, remove as much of the cause of the stain as possible.
    2. Do not dilute. Place an absorbent white cloth beneath stain. Apply solution directly to stain. Tap stain with your finger, pushing it onto the cloth beneath it.
    3. Rinse with warm water.
  6. For Large Stains

    In shallow bowl, immerse stained area in solution. Soak for 10-15 minutes. Gently rub fabric together and rinse with warm water. Repeat steps with fresh solution and longer soaking time, if necessary.


    Before use, test for colorfastness on an inconspicuous area.

    I tried Iron Out and it didn’t work to remove the rust stain (we have iron in our water and our treatment system wasn’t working) but this did! This stuff is great!

    The rust remover product works excellent! I had a white shirt for my son and after the first time he wore it, the shirt was stained with rust. This product took the rust out with ease. I highly recommend this product and will be buying it again!

    I just wanted to let you know that I have purchased my 3rd Carbona product and have yet again gotten the desired results from each product. There has been a rust stain on a pair of shorts and shirts for more than 5 months and I could not find the rust product in the food store. I was shopping one day and I got lucky and found the last bottle of stain devils #9 rust. I came home, put your product on the stain and washed them. Sure enough they were gone. So you know, I did try other products and nothing worked. I will definitely be telling everyone about how great I think Carbona is and continuing using only them in the future. Sincerely, A Very Satisfied customer

    When sunscreen got on my white clothing and left behind a stain similar to a perspiration stain, I used this product and the stain disappeared.

    I restore vintage linens. Rust spots are a common problem from old pins that have rusted on the fabric. Fortunately for me, I discovered Carbona Stain Devils several years ago, and they have helped me save MANY beautiful old linens and get them back into circulation. Now when I see rust, SD#9 is my “go to” product — because it works! You can see for yourself here:
