This should be fol- lowed up by a soapy wash, rinse, and dry as noted above. Tougher contaminants like bug splatters, bird droppings, and tree sap should be removed as soon as possible. If they dry on the surface of the wrap, they should be softened with hot soapy water be- fore washing to avoid damaging the wrap's surface. "Can I still take it through the car wash?" This is probably the most common ques- tion we get asked and the answer is, "Yes." But hand washing or touchless car washes are the best option to avoid dulling, lifting, or scratching of the surface of the graphics that can be caused by the brushes in some car washes. PRESSURE WASHING Since we do a lot of commercial wraps and fleet graphics, many of our customers use professional pressure washing companies to clean their vehicles. For larger vehicles and trailers, hand washing is too time-consum- ing, so pressure washing is the most efficient option. This means we often get asked about pres- sure washing, which is an option as long as it's done correctly. It's much easier to lift or remove graphics off a wrapped vehicle with a pressure washer, so we include a list of do's and don'ts on our handout: • Avoid excessive pressure • Do not spray damaged graphics as wa- ter can get under the graphic, causing lifting and curling • Do not direct the spray at a sharp angle to the graphics • Avoid spraying directly on wrap seams • Trim back all lifted edges and seal with an edge sealer or replace sections of graphics if necessary • Maximum water pressure: 800-2,000 PSI • Spray nozzle pattern: 40 degrees • Spray angle: 45 degrees, sweeping spray • Water temperature: maximum 72-80 F • Minimum distance of nozzle to graph- ic: 12"-18" • Never use a Turbo pressure nozzle WAX Another question we often hear is if the cus- tomer can wax over the wrap. I'm sure the thinking is that this will protect the graph- ics, but it could actually cause damage. We let our customers know that a Teflon-based polish is fine, and that they should look for one that is specifically designed for wraps. Carnauba-based waxes should be avoided. These waxes melt in the sun and become greasy, attracting dirt. The stain in the wax can also damage the surface of the graphics. If the wrap is a matte or textured finish, Excessive pressure or sharp angles can damage or remove graphics from the vehicle's surface. (Image courtesy Charity Jackson)
