What solvents can get rid of oil stains? What kind of solvent would you use to remove an oil based stain? 

I need help for a chemistry lab report and I tried to look it up but nothing seems to be helping me
Depending on where you live different dry-cleaning solvents are indeed the best choice. Perchloroethylene $\ce{Cl2C=CCl2}$ is probably still the easiest one to get.
