How can I effectively remove a bike grease stain from my clothing?

To effectively remove a bike grease stain from clothing, first blot the stain with a clean cloth to absorb excess grease. Then apply a pre-treatment stain remover or liquid laundry detergent directly to the stain. Gently rub the fabric together to work the detergent into the stain. Let it sit for a few minutes, then wash the clothing in the hottest water safe for the fabric. Check the stain before drying, and repeat the process if needed.
