Proraso Green
I use a special product, made for facial application. No longer in production. As per the cleaning part - good point, thank you, I will have to pay attention, in case I decide to do this pre-shave on regular basis. Usually I rub in the oil after the splash and before the balm, works fine as well.Watch out for irritation or even allergic reactions with pure essential oils. Some of them need to be diluted, I knew someone who made and sold her own candles and little perfumes and she got chemical burns from some undiluted essential oils. And I agree, shaving and pre-shaving oils are great products but they're a pain to clean off the instruments and surfaces when you're done. The best one I found was "shave secret oil" . It cost like $2 for a tiny bottle, almost like the size of clipper oil, and lasted me for 6 months because you only need 3-4 drops per shave. You can even shave with the oil alone without soap or cream.
