Using these Bikini Pinup Decals is easy. First, clean the surface where you want to apply the decal to make sure it's dry and free of dust. Then, carefully peel the decal from the backing paper and stick it onto the surface. Smooth out any air bubbles with a credit card or a similar flat object. When it comes to choosing a surface, make sure it's smooth and non - porous for the best adhesion. As for maintenance, avoid using abrasive cleaners on the decal. A mild soap and water solution is usually enough to keep it clean. If you need to remove the decal, gently peel it off from one corner. It should come off easily without leaving much residue.
