Avoid using your Steamfast Fabric Steamer on temperature-sensitive materials (suede, leather, waxed fabrics, or plastic), and surfaces prone to heat or moisture damage, such as delicate rugs, paper products, and unsealed wood or laminate.
For a clearer look at materials to avoid and why, here is a breakdown of what should never be exposed to your steamer:
Fabrics to Avoid
-
Leather & Suede: The high heat and moisture can permanently warp, stain, harden, or shrink both natural and synthetic leathers.
-
Waxed Fabrics: Steaming will melt the wax coating, ruining the finish and leaving stains.
-
Silk & Velvet: Extreme heat can cause delicate silk to spot or shrink. On velvet, high heat can permanently crush the "nap" (the raised fibres) and cause irreversible streaks.
-
Thin synthetics: Plastics or thin synthetics may melt, pucker, or bubble when directly hit with hot steam.
Household Items & Surfaces
-
Glued items: High heat weakens and melts adhesives, which will damage laminated items or glued upholstery.
-
Painted or wallpapered surfaces: Steam can strip paint off surfaces like wooden windowsills or toilet seats, and cause wallpaper to bubble or peel.
-
Electronics: Never steam clean objects with electrical components or touchscreens, as moisture can cause permanent damage.
-
Cold Glass: Spraying hot steam on a cold window or mirror can cause it to shatter due to thermal shock.
-
Biological Stains: Steaming pet urine or bodily fluids will "bake" or fixate the stain and odour into the fabric fibres.
Even on “safe” fabrics and surfaces, we always recommend that you spot test using the steamer in a discreet spot first to see how your fabric or surface reacts before using the steamer on the entire area. You can check your garment’s care instructions on the label. For household items and surfaces, refer to the manufacturer or manual.
