Solution using: “mix 7 oz. Borax, 3 oz. boric acid, and 2 qts. warm water” (soak & dry)


Note: According to the Bureau of Engraving and Printing , US paper currency is made up of 75% cotton and 25% linen

I’m fire retarding some emergency US Cash LONG term, but I’m concened about it destroying/disolving the cash over a long period(because of the acidity treatment).


Thanks for any help (any refs / links are extra appreciated!) : ) ,
