Can anyone suggest a tried-and-true procedure for cleaning out these spargers? When I worked in a synthetic lab, I used to clean fritted glass funnels with conc. HCL (I used nitric for a long time until a run-in with some leftover organic residue...), let them sit until all the acid dripped through, then wash with water, organic solvent (e.g. acetone) and then leave in the oven for at least 4 hours. This rarely got rid of the staining, however.
Any ideas most appreciated.
