I would not get pillows dry cleaned, even if it is possible, as I wouldn't like to sleep with my face pressed for 8 hours onto the chemicals they use. You can definitely get pillows, and duvets, washed and dried in a launderette. Launderette machines are bigger than domestic machines, which makes it easier to do bulky items. In an ideal world I would get my pillows/duvets washed at a launderette then bring them home to air dry in the sun.
