One of the most tedious tasks in many retail jobs is scraping away the adhesive left behind on hard surfaces where a sales tag has been removed. Some tags come off cleanly, but those with particularly tacky adhesive, or tags that have been in place for a long time, provide you with instant job security; the glue they leave behind may take a while to get off. Your best approach is usually to start with scraping, unless the surface is extraordinarily delicate, and then work your way up to scrubbing.
Instructions
1. Use the edge of a razor blade to very carefully scrape the leftover sales tag adhesive away; take care not to scratch the surface you're cleaning with the razor blade. If you're working with a very delicate surface that may be damaged by the razor blade, skip this step.
2. Dampen the tip of a rag with water, then add a drop or two of pure eucalyptus oil to the damp spot, and use this to scrub any remaining adhesive away. If you don't have any eucalyptus oil on hand--and it does have to be actual eucalyptus oil, not a synthetic imitation--try using any citrus oil like lemon or orange, or using an orange-based cleaner like CitraSolv.
3. Wipe the area clean with a damp rag--no oil or cleaner this time--both to remove any last traces of adhesive residue and to get the oil off the surface immediately; some volatile oils might discolor the surface you just cleaned if not wiped away.
