My grandfather grew up on a farm. He said they always had a bucket of corn husks in the outhouse and that was what you used. He was totally serious. If cheap toilet paper makes my bum feel raw, I can't even imagine what a corn husk would do to it.
I think you may have misheard him: farmers used to use corn cobs to wipe. https://www.farmersalmanac.com/what-did-people-use-before-to...
"In Rome, people cleaned themselves after using a public latrine with a sea sponge lashed to a stick, stored in a bucket of salt water or vinegar. It was considered polite to give the sponge a cursory rinse and a squeeze before putting it back in the bucket to get it ready for the next person."
