What is the proper way to get laboratory glassware clean?
“Wash labware as quickly as possible after use. If a thorough cleaning is not possible immediately, put glassware to soak in water. If labware is not cleaned immediately, it may become impossible to remove the residue. Most new glassware is slightly alkaline in reaction. For precision chemical tests, new glassware should be soaked several hours in acid water (a 1% solution of hydrochloric or nitric acid) before washing. Brushes with wooden or plastic handles are recommended as they will not scratch or abrade the glass surface.” See: http://www.corning.com/…/cleanglass.asp For more information.
