Anyone know how to dry clean at home?

Those at-home dry cleaning kits (the bag and sheet that go in the tumble dryer) freshen and de-wrinkle, they don't actually clean anything. For a sofa cover, a dry-clean-only label is usually about shrinkage, not about water wrecking it: hand wash in cool water with a wool wash, don't wring, dry flat or back on the cushions slightly damp so it stretches to size. Silk and anything structured with a lining I'd still send out.
