303® High Tech Fabric Guard NOT for Use on Synthetic Suede
The Label on the 303® Fabric Guard warns not to use it on "synthetic suede". Why Not?
303® Fabric Guard imparts enduring water repellency to all natural leathers - upholstery, clothing and footwear (including deerskin and suede). 303® Fabric Guard protects against soiling & staining as well as helps the leather be water resistant.
303® Fabric Guard should not be used on synthetic suede, not because of the product itself, but because of the carrier, Odorless Mineral Spirits (OMS), a mild solvent. As a general rule, even mild solvents should not be applied to rubbers & plastics. Synthetic suede is a plastic.
