Perfect. Good link and statement by Don. If you do not have bleach, use caustic media (NaOH solution, etc.).

1,2 ethanedithiol, a.k.a., 1, 2-dimercaptoethane, seems similar to ethyl mercaptan.   One method for dealing with ethyl mercaptan spills, as mentioned here is to apply 5% calcium hypochlorite.  Other sites mention household bleach (sodium hypochlorite).    Perhaps a dip in a dilute bleach solution as part of the glass washing process would do the trick.

Dear members,


Hope the Summer is finding you well and somewhat rested(?). A question came from  our sister school re:  working with Ethane dithiol in a glove box. Any thought on this? Also  what kind of  decontamination procedures for glassware before disposing?  We usually find glass only boxes full of smelly broken glass and our custodial group  would refuse to remove them.


Again thank you so much for any thought you may have.   Continue doing great work and enjoying the last of Summer.   


Best wishes
