How to take an oatmeal bath: Fill a knee-high nylon or thin sock without holes with 1/2 to 1 c. of oatmeal (not quick cooking or instant). Tie tightly at the top. Place it in your warm bath, with you, and squeeze it softly every so often to release the oatmeal “water.” Before leaving the bathtub, scrub your entire body lightly with the sock. To clean: Over a trash can, turn the sock inside out and scrape all of the oatmeal off the outside, then rinse well with warm water. Wash as normal.
