WASH & WHIPS Car Wash Kit - 3-Gallon Bucket with Particle Interceptor Trap, Shampoo, Chenille Mitt & Microfiber Soft Towel, 5pcs * 3-Gallon Bucket & Particle Interceptor: This kit includes a 3-gallon bucket made from high-density polyethylene construction and the Pit Stop Particle Interceptor. The Pit Stop Particle Interceptor is designed to fit perfectly in standard 12-inch buckets, reducing the risk of swirls and scratches. * Prevents Swirls and Scratches: The bucket's technology separates abrasive dirt and debris from the wash water, protecting your vehicle's delicate finish during cleaning. The textured underside and small holes act as a one-way valve, capturing spent dirt at the bottom of the bucket, ensuring it doesn't get back on your car's surface.
