Not that this has to do with pickle, but for a great general
cleaner, with minimal side effects, sprinkle coarse salt & baking
soda over the area to be cleaned (sinks, tubs, counters…etc) pour
some vinegar over it. use a scrubbie or sponge and wipe vigorously.
Rinse well. Cleans like a charm. Just all the talk about
vinegar/salt, etc reminded me. Oh, and I will be in the SF Bay Area
for Memorial Wknd, just down in SJ. Very bummed I can’t make it up to
the conference. 
aj in cool, spring MN. Where my lilacs are blooming!
