Known for revolutionizing the rinseless car wash with ONR No Rinse, Optimum Polymer Technologies is devoted to innovate car detailing products for professional detailers and serious enthusiasts. We have always pushed boundaries with ONR and our industry leading ceramic coatings, and now have transformed a trusted classic with a purpose-built design update. We've taken the Big Red Sponge, and made a more controllable and streamlined version that will make you a more effective detailer. After testing a full range of contoured sponges, our easy-grip profile has a squared interior edge for a more positive grip, allowing greater control as you wash. We looked at hard-to-reach areas, like mirrors and door handles, and created a pointed edge for better access, so you don't miss a spot. Our new angled cross-cut pattern is designed to more effectively trap dirt and protect the vehicle surface as you agitate at different angles. Like the BRS, the BRS 2.0 is designed for rinseless car washes and traditional bucket washes with your favorite car soap or car shampoo. A great addition to the BRS, use the original BRS to wash large areas, and use the BRS 2.0 to access tight spaces and tackle wheels. Ditch the knock offs and go with a USA-made Big Red for a pro level detail. OPT manufactures and develops a full range of car wash products in Memphis, TN USA.
