Hi Mario and Eric,
I have had some very bad experiances with dry cleaning of wool garments (not uniforms), it depends on the quality of your dry cleaner. I have a friend who had several hundred uniforms damaged in a flooded basement, and dry cleaning was the only way that some of the were successfully salvaged, but for a uniform that is just a bit dirty, I would not dry clean, as the chance of damage is too great, and even if it is not actually damaged, the cleaning process can not be good for the longterm condition of the fibers.
