Thank You scrutinizer. :g/^ *#/d cannot take care of TABs.

ie. It cannot remove the line with #some comment1 shown below which has a TAB at the beginning. Any idea , how lines with TABs can also be dealt with ? Using vi or some other utility ?

Code:
$ cat config.properties2
    #some comment1 
parameter1=blablah
#some more comment2
another parameter=blablah
#another comment3
parameter3=xyz
