Chromex 99% Isopropyl Alcohol, 1 Gallon (128 Fl Oz). Anhydrous - under one percent water - so it flashes off without leaving a film behind. That is what puts it on a service truck: wiping flux and paste residue off copper before a joint gets soldered, pulling moisture out of a gauge port or a line, cleaning thermostats, contacts and control boards with no rinse step after. Bottled in the USA. ANHYDROUS, UNDER 1% WATER - flashes off with no film left behind, so a soldered joint, a contact or a control board is ready to work on as soon as it dries. BUILT FOR SERVICE WORK - flux residue off copper before soldering, moisture out of gauge ports and lines, thermostats and contacts wiped down between calls. PACKAGED FOR THE VAN - one 128 fl oz jug. Sealed jug with a tight cap, so a partly used container rides along without weeping. MADE AND BOTTLED IN THE USA - consistent purity batch after batch, so the jug you open next month behaves like the one you opened today. FLAMMABLE LIQUID - use in a ventilated space away from heat, sparks and open flame, and keep it tightly capped. UN1219, Packing Group II.
