@captainsnowball 70% IPA still contains 30% water. So you may add water to an already water damaged board. Don't use it!
 
Isopropyl alcohol has good solvating characteristics for removal of fluxes, ionic contaminants, residues, organics, oils, greases, fingerprints, water, and particulates. It removes moisture to submicron levels specifically in the higher percentage rangesranges (hydrophilic properties) . I use nothing less than 91% (Walmart ~$2.50) but prefer my 99% from TrueValue Hardware

Denatured alcohol is actual ethanol (C2H6O)that has added substances to make it inedible :-J. Those substances can be kerosene, acetone, turpentine or naphtha (and yes even isopropyl alcohol (C3H8O)) etc. and thus not something you want to use to clean your board of water damage. Let your teacher know that the distinction here is that denatured alcohol is a process whereas isopropyl alcohol is a product.
