What is the best way to get spaghetti sauce out of a grey t-shirt?

To remove spaghetti sauce from a grey t-shirt, first, gently blot the stain with a clean cloth to absorb excess sauce without rubbing it in. Rinse the affected area with cold water to dilute the stain. Apply a stain remover or a mixture of liquid laundry detergent and water, let it sit for about 5-10 minutes, then wash the shirt in cold water. Check the stain before drying; if it persists, repeat the process.
