Bleaching is a careful cleaning process used in manuscript and document restoration to make yellowed or discolored papers whiter and more readable. It's similar to how we might brighten white clothes, but with specially controlled methods safe for delicate historical documents. Restoration specialists use this technique to remove stains, age-related yellowing, or damage from water and mold, while being very careful not to harm the original text or artwork. This is just one of many conservation methods, along with deacidification and stabilization, that helps preserve important documents for future generations.
