Half. It gives good step-by-step methods for common stains, but fabrics react differently. Always check the care label and test on a hidden spot first.
01Why half-bot
- Stain removal methods are well documented.

I'd be happy to help you remove the red wine stain from your 100% cotton shirt. Here are the steps to follow: 1. **Act quickly, but gently**: Since the stain is still slightly damp, we'll start by blotting it with a clean white cloth to remove any excess wine. Don't rub the stain, as this can push it deeper into the fabric. 2. **Test a hidden spot**: Before applying any cleaning solutions, test a small, hidden area of the shirt (like the inside seam or a hem) with a tiny amount of liquid dish soap and water to ensure it won't damage the fabric. Gently apply the solution, let it sit for a minute, and then rinse with cold water and blot dry. 3. **Apply dish soap and water**: If the test area looks okay, mix a small amount of liquid dish soap with cold water in the bowl. Dip a clean white cloth into the solution, blot the stain gently, and work from the outside in. Don't soak the fabric, just apply a small amount of solution to the stain. 4. **Rinse and blot**: Use a clean, damp white cloth to rinse the soap off the stain, and then blot it dry with another clean white cloth. 5. **Apply white vinegar**: If the stain is still visible after rinsing and blotting, mix equal parts white distilled vinegar and water in the bowl. Dip a clean white cloth into the solution, blot the stain gently, and work from the outside in. Let it sit for about 10 minutes, and then rinse with cold water and blot dry. 6. **Check the stain**: If the stain is still visible after the vinegar treatment, it's time to consider taking it to a dry cleaner. However, if you'd like to try one more thing, you can sprinkle a small amount of baking soda over the stain, let it sit for about an hour, and then brush it off with the soft-bristled toothbrush. 7. **Wash the shirt**: If the stain is removed or significantly faded, wash the shirt in the washing machine according to the care label instructions (machine wash warm, 30°C, non-bleach). 8. **Take it to a dry cleaner**: If the stain is still visible after trying the above steps, it's best to take the shirt to a professional dry cleaner. They will have the necessary equipment and expertise to remove the stain without damaging the fabric. Remember to always follow the care label instructions and test any cleaning solutions on a hidden spot first to ensure the best results.

The made-up sample (a messier one):
[WHAT IT IS, HOW OLD]A dark brown, slightly crusted sauce stain (looks like a curry/tomato mix) on the left sleeve of my sweater. I think it happened about 5‑7 days ago after dinner.[FABRIC, LABEL INSTRUCTIONS]100% wool sweater, label reads: "Hand wash cold, gentle cycle only. Do not bleach. Tumble dry low. Iron on low heat. Dry clean recommended for tough stains."[SUPPLIES]I have liquid dish soap, white vinegar, baking soda, a soft white cloth, a small bowl, cold water, and a gentle wool detergent (like Woolite). No commercial stain remover.

What came back (excerpt):
Use a soft white cloth to gently blot the stain, focusing on soaking up as much of the excess sauce as possible. Do not rub the stain, as this can push it deeper into the fabric.

Given the care label and the available cleaning agents, here's a step-by-step guide to help you remove the stain: 1. **Test on a hidden spot first**: Before attempting to remove the stain, apply a small amount of the gentle wool detergent (like Woolite) to a hidden area of the sweater, such as the underside of the sleeve or a seam. Gently rub the detergent into the fabric with a soft white cloth, then rinse with cold water and let it dry. This will ensure that the detergent doesn't damage the wool fabric. 2. **Blot the stain**: Use a soft white cloth to gently blot the stain, focusing on soaking up as much of the excess sauce as possible. Do not rub the stain, as this can push it deeper into the fabric. 3. **Dilute detergent solution**: In a small bowl, mix 1 part gentle wool detergent with 2 parts cold water. Stir the solution gently to create a mild cleaning agent. 4. **Apply detergent solution**: Dip a soft white cloth into the diluted detergent solution, blot the stain gently, and work from the outside in. Avoid soaking the sweater or applying too much pressure, which can damage the wool fibers. 5. **Rinse and blot**: Use cold water to rinse the soap off the cloth, then blot the stain again to remove as much of the detergent as possible. 6. **White vinegar treatment**: If the stain persists, you can try applying white vinegar directly to the stain. Dilute the vinegar with an equal amount of cold water, then use a soft white cloth to gently blot the stain. Let it sit for about 10-15 minutes before rinsing with cold water and blotting again. 7. **Baking soda paste (optional)**: If the stain is still visible after the previous steps, you can try making a baking soda paste. Mix 1 tablespoon of baking soda with 2 tablespoons of cold water to form a paste. Apply the paste to the stain and let it sit for about 30 minutes to an hour. Then, rinse with cold water and blot dry. 8. **Assess and repeat**: If the stain is still visible after these steps, you can repeat the process. However, be cautious not to over-saturate or over-manipulate the wool fabric, as this can cause damage. 9. **Consider dry cleaning**: If the stain remains after attempting the above steps, it's likely that the stain has set and may require professional cleaning. Given the care label's recommendation to dry clean for tough stains, it's best to take the sweater to a dry cleaner specializing in wool garments. They will have the necessary expertise and equipment to safely remove the stain without damaging the fabric. Remember to always prioritize the care label's instructions and handle the wool sweater with care to maintain its quality and longevity.

How each run works: we fill the prompt with a made-up sample, run it once in Llama 3.3 70B, and GPT-OSS 120B grades the answer against the prompt's own rules. Word limits are counted by code, and every quote flagged as made up is checked against the full answer. Your results can differ. How we test.
