Spot Cleaning
As the name implies this is treating an individual spot of dirt or grease. The technique involves carefully working at the dirt, grease or tape adhesive residue with a cotton bud that is liberally wetted with a suitable solvent (not water!). Work from the edge of the spot towards the centre as this tends to leave less residue to deal with.
All safety precautions such as good ventilation and protective equipment must be adhered to.
