Several chemicals found in household products can be used to take ink off paper. These chemicals include acetone, benzene, bleach and carbon tetrachloride, according to the National Check Fraud Center.
Acetone is a common solvent in many cleaning agents. Bleach can be found in many products for washing laundry. Carbon tetrachloride can be found in carpet cleaning agents. Other chemicals used include Chloromice T, a mild form of bleach found in detergent for washing diapers, and Fox IT, which is used by stamp collectors. Clear correction fluids and a high performance eraser can also be used. Criminals use these chemicals to take the ink off checks to change their amounts and names in a process known as check washing.
