Surprising Citrus Clean: Carpet Upholstery vs. Multi-Safe tested = Win! We were intrigued by the Chemical Guys CWS20316 Foaming Citrus Fabric Cleaner when it promised to tackle everything from car carpets to office upholstery. The 16 fl oz bottle felt petite, but its citrus scent was surprisingly invigorating—not overly sweet or artificial. We tested it on a stubborn coffee stain on our living room rug and a dirty car seat, and the foaming action was efficient, lifting grime without harsh chemicals. The multi-safe label held true; we even used a tiny amount on our office microfiber chairs without any damage. While it wasn’t a heavy-duty degreaser for industrial use, it excelled in versatility. The cleanup was easy, and the lingering citrus freshener was a delightful bonus. For us, it’s a winning product for quick, reliable, and safe cleanups—perfect for homes, cars, and beyond.
