Whoa would never think to this technique on my own

Once the chalk is removed, pop the stained garment into the washing machine and wash it as you normally would. Use the warmest water temperature that’s safe for the fabric in question, as heat can help break down any remaining grease. If the stain is still visible after the first wash, repeat the chalk application before drying.
Step 7: Air Dry (Optional)
If you're worried about any remaining stain, avoid putting the fabric in the dryer. Heat from the dryer can set a stain if it's not fully removed. Instead, let the fabric air dry and check for any leftover grease spots. If there’s still a bit of the stain remaining, repeat the chalk process again.
Additional Tips and Tricks
Prevention is key: If you know you’ll be in a greasy environment (like a barbecue or restaurant kitchen), consider carrying a small piece of chalk with you. Treating grease stains immediately can make all the difference in how easily they come out.
Works on other oily stains too: Chalk isn’t just limited to removing grease from cooking. It works well on motor oil, lotion, and even makeup stains. Anytime you encounter an oil-based stain, reach for the chalk!
Be cautious with delicate fabrics: While chalk is generally safe to use on most fabrics, always do a small patch test on delicate materials like silk to ensure it doesn’t leave any chalk residue or damage the fabric.
Pair with other household cleaners: In case the chalk alone doesn’t completely remove the stain, you can follow up with a dish soap treatment (known for breaking down grease) or a sprinkle of baking soda for an added boost before washing.
