Can the Revive Fabric Shaver be used on all materials?

The Revive Fabric Shaver may not be appropriate for use on all types of fabrics. Using it on delicate fabrics such as angora wool, or fabrics of a “textured” or raised knit design may damage them. We recommend first testing your shaver on an unnoticeable section of fabric. Use light strokes - do not press into the garment. This product should not be used on down or feather clothing.
