Using these Dirty Diesel Decals is easy. First, clean the surface where you want to stick the decal, like your truck, toolbox, or toys. Make sure it's dry and free of dust. Then, carefully peel off the backing paper from the decal and place it on the surface. Smooth it out with your fingers to remove any air bubbles. When it comes to care, just wash it with mild soap and water occasionally. Avoid using sharp objects on the decal to prevent scratches. Also, don't expose it to extremely high temperatures for long periods, as this could affect its adhesion.
