roller disinfecting

[Spring~Roll]

Hello. I bought the roller with the shortest needles but I have not used it yet. Is it alright to spray the roller with 70% ethyl alcohol, or do I have to soak it?

The problem with spraying is that it does not remove skin detrius (spraying only wets it, does not remove it), so it has time to develop bacterial growth between rolls. A 0.2 mm roller however does not need to be sterilized every time you use it, only cleaned in some lukewarm water with a drop of dishwashing liquid and then rinsed and left to dry - (to remove skin flakes, oil from the skin etc.)

I see. Thanks for the help!
