All our decals are waterproof, weather-resistant, and car wash-safe. Standard automated car washes are more than acceptable; however, you'll want to stay away from high-pressure washers and power washers. Disrupting the adhesive backside with water can damage the adhesives bond, and the aggressive nature of pressurized water can cause the vinyl to separate from your installed surface. In short, car washes are okay, but car washes using power washers are not!
