Unfortunately I can't stand the smell of the stuff, so I added a few drops of lime essential oil to help mask it a bit. The measures below will create about 60ml (give or take depending on the essential oil), you should increase proportionally if you need more - to be effective the alcohol content must be at least 60%, the measures given will create a 64% concentration (assuming your total essential oil addition weighs in at 1ml, which is perhaps over generous).
