I mean sure, the shower helps some! But it's no match for this gem, which is safe to use on cotton, wool, linen, nylon blends, and sequins and beads. And — although the listing doesn't explicitly say so — many reviewers safely use it on silk (you'd just want to make sure the dyes wouldn't spot, first).
Promising review: "This little thing is fantastic!! Its amazingly simple to use: just fill with water, plug it in, flip the switch to 'on' and give it about a minute. So far I've used it on my work shirts and pants but fully plan on using it on anything that isn't synthetic. Depending on how set in the wrinkles are you can get about 2–3 shirts done on a single fill, but once you refill you don't have to wait as long for it to be ready to use again. The photos I've attached are of a shirt that was brand new out of the packaging so the wrinkles were pretty set in, but after about two minutes it was fully work ready. I have a ton of weddings requiring overnight travel this year and this will definitely be coming to all of them." —Ruari O'Shea
