Title: Getting water out of decanters, bottles, etc
Post by: ahremck on April 29, 2011, 02:45:20 PM: I have from time to time found this to be a pain - especially the last couple of drops. I came across this suggestion that I passed on to a friend some time back. Hope it is useful to someone else.

Find an airtight(as close as possible) box that will fit the decanter plus a small open plastic container(or an old tin) which will have Calcium Chloride in it. Calcium Chloride is very hygroscopic – it seeks out water. It will eventually dissolve itself in the water it extracts from the air. It is closely related to salt (Sodium Chloride) so care must be taken to keep it away from metals or they will corrode rapidly. It can be bought at a Chemist’s I seem to remember. Place the Calcium Chloride in the plastic container and seal the box. Check regularly and you will find it extracts the water from the air so that in the bottle (or decanter) will evaporate and is then trapped. You can re-use the calcium chloride by gently boiling the water away until you havre the dry "salt" again.

Invert to get the alcohol out. Alcohol absorbs water. We use it in histological labs to dry water from tissues. Works wonderfully and quickly for glass.

Just buy some 91% Isolpropyl Alcohol, add 1/2" to the piece & swirl it around, pour it out & stand it upright to drain what few drops of alcohol are left. It will displace any water & the alcohol will evaporate within 5 minutes leaving it spotless.

Edit: Well I see Anita & I were posting at approx the same time.

(I did once. Lost my eyebrows, but I nearly lost the contents of my bowels as well.)

The easiest way to get the last bit of water out is to do the final rinse in distilled/deionised water, then shove in a wick of kitchen roll. It's hygroscopic and will grab hold of any moisture.

(But I keep distilled water in the house at all times anyway - I need it for my insectivorous plants)
