Whoa! Using compressed air is a bad idea, unless it goes through special designed ionizing air guns.  Compressed air will create a static charge and may kill your circuits if you have semiconductors.  Use a soft tooth brush lightly.  Or clean with electrolube SWAS, then dry it properly in the oven for say 24 hours at 70 degrees C.
