If you've discovered that someone sloppily spilt curry on your refrigerator seal (or gasket) as they stowed leftovers inside, you may also find that the curry will leave a yellowish stain. If you've tried to clean the gasket using a soapy rag and water and the stain persists, look to your bathroom for help.
Place a pea-sized amount of whitening toothpaste on the old toothbrush. Be sure you have toothpaste and not gel, as gel does not work to remove stains on your refrigerator gasket.
Scrub the stain gently with the toothbrush and toothpaste. Close the refrigerator and allow the toothpaste to remain for 30 minutes, then go back over the stain with the toothbrush.
Dip a rag in soapy water and wipe the toothpaste from your refrigerator gasket. Wipe the surrounding area that may have come into contact with the toothpaste while the refrigerator was closed.
Dry the gasket and surrounding area with a dry rag.
