Removing Grease Spots- Laundry

I was just saying to myself- "Why can I never get grease out of my clothing?  It's a common problem- a little spatter during cooking, C helping Dad wash the car and leaning into something (like a greasy tire), Dad changing the oil...and so much more.  I've tried so many things and rarely get a grease stain out.   I wonder what other ideas are out there?"  Two days later- a solution.  Or so I thought.

Re-nest suggests the use of chalk.  Wipe some on top of the grease stain and it will soak up the moisture so it actually comes clean in the wash.

I tried this idea and it didn't work.  Is there something I'm missing?

Instead I went to my fallback that sometimes, truly, maybe 30% of the time works.  I dabbed some dawn on the spot and let it sit for about an hour and rewashed.  The grease was gone- thank goodness.

I'd like to say thanks to my friends who suggested the use of oxiclean for poopy undies.  Yeah- something they don't tell you about when you have a child.

Do you have a favorite way to remove grease stains or other laundry tricks?  I'd love to hear them.
