To ensure the longevity of the red paint and realistic wood look of your polyurethane sign, please observe the following care instructions: Clean the sign regularly with a mild soapy solution and a soft microfiber cloth to remove dust and dirt. Absolutely avoid harsh cleaning agents, solvents such as alcohol or acetone, and abrasive sponges, as these can dull the surface or damage the paint. Protect the sign from prolonged, direct exposure to the elements and extreme UV radiation to prevent fading. When storing the sign, ensure adequate air circulation and avoid tightly fitting plastic packaging to prevent blistering or peeling of the coating due to trapped moisture.
