Abstract
Iodine and iodophor stains are masked by applying to the stain sufficient starch to impart a bluer coloration to and thereby mask the stain. The masked stain can be left as is until further cleaning or other surface repair or replacement can take place. The masked stain may instead or also be subjected to the action of a suitable decolorizing agent. Meanwhile, the masked stain typically will be much less objectionable in appearance than the original stain.
