I've been doing some cell work in a biosafety cabinet and use 70% ethanol to spray down everything that goes into it. I spray my gloves and rub them together and then spray and rub the containers before putting them inside the cabinet. I've been noticing lately that after the ethanol dries that it leaves a white residue on the surface of the containers etc. I've thoroughly washed and rinsed the entire ethanol bottle and filled it up with new ethanol but it still keeps happening. Any ideas?
