Removing pressure-sensitive adhesive is similar to a science experiment that is largely based on trial and error in combination with knowledge gained from experience. As of 2010, there are seven pressure sensitive adhesive types being manufactured that range from permanent acrylic, which is intended for indoor and outdoor permanent adhesion projects, through badge, which is intended for temporary sticker-type badge applications. With the correct solvent it is possible to remove pressure-sensitive adhesive without damaging the surface it is on.
Natural Oil-Based Adhesive Remover
Pour a small amount of natural oil-based adhesive remover, such as one containing orange oil, on a clean cotton cloth.
Rub the dampened cloth over the adhesive until it starts to ball up on the cloth.
Press the edge of a small paint scraper against the remaining adhesive and use it to scrape it off of the surface.
Pour a small amount of an acetone-containing solvent on a clean cotton cloth.
Place the cloth over the pressure-sensitive adhesive and allow it to sit against it for five minutes.
Rub the adhesive off of the surface with the acetone-dampened cloth.
