I’d say laundromat. If you don’t want to do that and don’t want to pay, do you have a bathtub? Put in water, a very little detergent (or cleaning vinegar, but not both together) let it soak quite a while, then dry it in the dryer.
Alternatively, if not visibly dirty you can just run it through a long hot dryer cycle (add some tennis or laundry balls) and that will help at least get rid of some of residual dust, dust mites and dead skin cells.
King size comforters are one reason we always get washers with large enough tubs.
