An ultra-violet tag dye, visible only when exposed to ultra-violet light is blended with a fabric protection compound in a suitable evaporative carrier for application to a fabric so that, after evaporation of the carrier, the extent of coverage can only be detected visually by exposure to ultra-violet light. A suitable fluorescent dye has the composition 2,2'-(2,5-thiophenediyl) bis (5-tert-butylbenzoxazole).
