Waxy finish on cotton pillowcases - how to undo?
Our cotton poplin pillowcases have developed a stiff and "waxy" feeling to them.
We have two such sets, and they're interchanged and washed every week, and used for maybe eight months a year, and we've had them for maybe three years. These are 100% cotton.
I'd presume that it's our normal oils from our scalp and hair that are doing this. But it's never happened with our 100% cotton flannel pillowcases, which we use, wash, and put back on the bed every week for the four winter months. And it never happens with the sheets that match the "waxy" pillowcases.
I'm less concerned with the cause than with the cure though. What might I do to treat the pillowcases to remove the "wax" and possibly prevent the problem from occurring again?
They're washed in cold water, with regular Tide and no fabric softener, and dried in an electric drier with moisture sensor.
