Happy to see this thread. I'm having a bag washing emergency!
I'm in Spain, trying how to figure out how to clean vomit off my Synapse and Aeronaut. Thanks to a random woman on the meto for puking on my back and bags. We have only 3 nights before we move cities, and I'm thinking I'll have to spot clean instead of soak, for fear that the bags won't dry in time. I am so grossed out by the fact that all many little crevices and buckles seem to have gotten vomit in them.
5 minutes into my visit to Madrid, and I'm covered in vomit. Gag.
