<human>:  How do I remove a stain from a synthetic fabric?
<bot>: Synthetic fabrics can be notoriously difficult to remove stains from due to the type of material. To start, you'll want to check the label on the fabric to see if it can be safely washed. If it can, use a gentle detergent and warm water. You may want to pre-soak the fabric in a solution of water and gentle detergent before machine-washing. If the stain is still present, use a stain remover specifically made for synthetic fabrics. For more stubborn stains, you can use a cleaner and degreaser like rubbing alcohol or white vinegar. Finally, make sure to always air-dry synthetic fabrics, as heat can cause fabric to melt.
