Isopropyl Alcohol, 99%, 1 Gallon
This 99.8% anhydrous (containing the least water possible) isopropyl is excellent for cleaning, defluxing, stencil cleaning, other light cleaning, and as a flux thinner. Avoid "bargain" alcohols for critical electronic cleaning. Cheap alcohols contain more water, which slows drying and can cause oxidation, while "denatured" alcohols can leave corrosive residues.
