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: "I LOVE this thing!! I bought it as an alternative to an iron (who has time to take out a big ironing board and heat up an iron in the morning??), and it was perfect. Some reviews, I believe, say it runs out of water easily, which I have not found to be true. Just be sure to screw the cap on tightly after refilling because that boiling water WILL spill out onto your hand and it HURTS! I have used this steamer on all kinds of clothes: sweaters, dresses, blazers, light blouses of all colors; it works very well on everything. Super easy to use." —AJ
