text: Safety hazards of bleaching chemicals and methods; some bleaches are toxic or explosive and must be disposed of properly.
text: Disadvantages: Should not be used on paper with conspicuous traces or stains of heavy metals (e.g., iron, copper) or their salts or oxides (can promote decomposition of bleach and increase mechanical and oxidative deterioration of paper); can degrade paper if improperly used or stabilized since H 2 O 2 may decompose to release oxygen gas; in some cases darkening of paper may occur and stain may return in a very short time, as little as a few months; oxygen gas evolution during immersion can blister short fibered, degraded, mold damaged, or thick, laminated papers; can sensitize paper to light if residues not removed; can bleach iron gall ink; hydrogen peroxide (or its by-products) and ether can be explosive, even at room temperature.
