Is removing grease stains from clothes a job i can do myself?

yes, easily. dish soap is literally made to cut grease. work a few drops into the stain from both sides with your fingers or an old toothbrush, leave it 15-20 min, then wash in the warmest water the label allows. if the stain is still fresh and oily, put cornflour or baking soda on it first to soak up the excess. main thing is check it before it goes in the dryer. heat sets grease and then it's really there for good.
