Clean glassware is simple and fundamental in organic chemistry practice. The knowledge of how to remove tough stains, residues, and contaminates provides the confidence to use glassware without worry of contamination.

By following the guidelines to cleaning glassware, the chemist can focus on the chemistry and worry less about contamination from glassware. The above protocol demonstrated how to clean glassware using warm, soapy water, acid wash, base bath, and aqua regia, and how to dry glassware, as well as advice for cleaning glass ground joints. Disposal of cleaning solutions were also discussed briefly. These glass cleaning procedures work for all kinds of glassware including, but not limited to: round-bottom flasks, Erlenmeyer fl
