How do I remove adhesive from a painted surface?

Woodwork is often treated with a thin transparent-colored liquid that changes the color of the work without hiding the grain of the wood, and if the latter is good a very fine result is obtained. Sometimes the stain is produced by the combination of two or more chemicals applied separately, or soluble pigments may be mixed with a transparent vehicle and applied in the usual way. The vehicles for the pigments vary considerably, and include water, methylated spirit, size, turpentine and clear raw linseed oil. Varnish is made by dissolving certain gums in linseed oil, turpentine, spirit or water. They give a transparent protective coat to painted and stained surfaces or to wallpaper or plain woodwork. Varnishes usually dry with a very smooth, hard and shiny surface, but flat or dead surfaces that are without gloss may be obtained with special varnish. The gums used for hardwearing or carriage varnishes, such as those to be exposed to the weather and frequently cleaned and polished, are amber, copal and gum anime. Amber is a yellow transparent or clouded gum found on the coasts of the Baltic, and particularly in Prussia. It makes a hard, durable and slow-drying varnish that does not darken with age. Copal gum is brought from the West India Islands and also from the East Indies. It makes the most durable varnish, and being tough and hard is generally used for external work. Gum anime, is a variety of copal found in the sandy soil of the East Indies.
