Clean the area thoroughly with rubbing alcohol or soap and water. Do not use Window cleaning products as they can leave a residue behind that will prevent the sticker from adhering well.
Firmly rub a squeegee or credit card over the top of the clear transfer tape. This removes any air bubbles that may have formed and makes the sticker cling to the transfer tape.
Peel the transfer paper and the sticker away from the backing paper. If the sticker stays on the backing, slowly replace the paper backing and repeat Step 2.
Apply the sticker to the cleaned area and rub over the transfer tape with a squeegee or credit card.
Slowly peel the clear transfer tape off at an angle at 45 degrees. Be careful that you don’t pull the sticker off the surface. If sticker pulls away from the surface, lay it back down and repeat Step 4.
