We only put DI water on the sponges, from a spray bottle. One of the
soldering iron manufacturer's sites, perhaps Metcal's site, claims that
using DI water on the sponge will make your tips last longer. Not having
that much free time I haven't tried to prove or disprove that, but using DI
can't hurt, and it means 1 less source of possible contamination.
We use a spray bottle because our environmental auditor was concerned that
running the sponge under a tap may wash bits of lead (solder) into the
drain.
Maybe we could let the operators drink DI water??? Seriously, our fix is to
have fountains in the area.

Hi Brian,
Thanks for the reply. You say that there may be a problem with spills but
it's only water, nothing else is allowed. You put water on your sponges and
in a lot of companies people keep a small bottle of water on their bench to
refresh this sponge.
