Stopped by the bar to meet some friends last night. A block after hopping on my townie I realized I neglected to roll up my right leg. I now have grease stains all inside the leg of my new pants (arrived in the mail hours earlier - never even been washed).

Whats my best bet? Simple green? Mineral spirits? They're a pair of khaki dockers - cant use anything that might alter the color of the fabric.
