How to Remove Mud Stains

18-year-old Helena Muffly wrote exactly 100 years ago today: 

Sunday, November 9, 1913:  Went to Sunday school this morning although I doubted at first whether I would get there or not. It rained pretty hard before I was ready and rained coming home. Got the back of my coat rather wet.

Her middle-aged granddaughter’s comments 100 years later:

Sounds like really yucky weather. I can just picture Grandma traipsing down the dirt road that ran past her house through the cold rain, trying to avoid mud puddles and other particularly muddy spots.

Did she get any mud on the back of her coat? Here’s some hundred-year-old advice for getting rid of mud stains:

Mud Stains:  On dark clothes, allow them to dry thoroughly before attempting to remove them. Then a brisk brushing will probably take all the mud away without leaving any traces of the ugly mark that would have remained otherwise. If not, rubbing with grated raw potato will often take away a bad mud stain.

Grated raw potato will get rid of mud stains? . . . really? I almost want to smear some mud on my clothes so that I can see if this really works.
