One of my DIR firends when in fact I did flooded my 1st stage after soaking it with the dust cup on sold me a tip. - After the dive in the resort - as mentioned by Marek - while the regulator is still attached to the tank simply pure a bottle of mineral water over the first stage. The same with 2nd stage, unattached it and then put the dust cap on.
Max - I've flooded the DIN because all my regulators are DIN.
