Sta-Kleen Silicone, part of the Sta-Kleen family of coated fabrics from Mitchell Faux Leathers, stands up to quaternary, phenol, and ammonia-based chemical cleaners. Sta-Kleen Silicone has passed the colorfastness to light test at a minimum of 1,500 hours, which measures a coated fabric’s ability to resist fading, gloss change, and surface deterioration.
