Using this Cobb Tuning rear wiper delete is a breeze. First, remove the old rear wiper arm from your vehicle. Then, take the new wiper delete and follow the included installation guide to attach it to the rear glass. Make sure to use the provided O - ring, bumpers, and nylon nut for a tight and secure fit. When it comes to maintenance, since it has a durable black powder - coat finish, you can simply wash it with mild soap and water during your regular car wash. Avoid using abrasive cleaners as they might scratch the finish. Keep an eye on the O - ring and bumpers over time; if they start to show signs of wear, you may need to replace them to maintain the tight seal against the glass.
