What brand do you recommend in a stain remover for grease and oil stains on clothes?

The one I use for my four year old son who gets into everything, is oxy stain remover.  This is from Woolite.  It says it is for carpets.  Well let me tell you, it works on clothes.  It is impossible to get some stains out of my sons but this works magically.  You just spray it on. You don't have to scrub at all.  Let the spray dry a little and throw in the washer.  Pull it out to make sure the stain has disappeared.  Sometimes I do wash it twice just to make sure it is gone.  My son is really hard on his clothes and it works for us.  You should really give this a try.  I hope it works for you as well.  Thank you for the question.
