Rejuvenate® soap scum remover is specifically designed to power through tough soap scum buildup and grime without harsh scrubbing. Gentle enough for daily use, this non-bleach, non-abrasive formula is safe on glass showers and multiple surfaces, including ceramic tile, chrome, plastic, and fiberglass. Simply spray and rinse to easily remove soap scum. Always test on an inconspicuous area first. To use, spray directly onto a wet surface, then allow the product to penetrate. Once complete, rinse surface thoroughly with water. For tougher soap scum buildup, allow the product to sit for 2-3 minutes and repeat as necessary. <br><br>Note: this product does not remove hard water stains, mold, or mildew.
