From: Dan.Marsick**At_Symbol_Here**eh.doe.gov Date: August 18, 2005 8:12:16 AM EDT (CA) We are conducting an accident investigation at a DOE lab. The activity involved cleaning of laboratory glassware, Buchner funnels, plated with gold residue by immersing in aqua regia. Does anyone have an alternate, less hazardous method for removing gold residue from glassware? Daniel J. Marsick EH-52/ US Dept of Energy (301) 903-3954
