I've found a lot of great cleaning tips and recipes on various blogs, so I thought I'd share one of my DIY concoctions. Actually my dermatologist gave me the "recipe" about 5 years ago, but I've been using it and saving money ever since.
Equal parts rubbing alcohol, witch hazel and regular water. Pour each one in the bottle of your choice (I still use my old Clinique pump), and give it a little shake to mix everything. Done. This works well for normal to oily skin, but may be a bit harsh for sensitive skin.
