Zen-Xero's super water-repellent coatings have excellent dirt protection and ease of maintenance. Ordinarily, you should use a special maintenance shampoo on them, but depending on the vehicle’s storage conditions and maintenance methods, dirt may inevitably adhere to them. Such dirt can be cleaned using this special Zen-Xero maintenance cleaner. Apply it to a sponge and gently clean the surface to remove the dirt and revitalize the coating. Rubbing too vigorously can damage the Zen-Xero water-repellent coatings, so be careful when cleaning.
