Question: can i use surgical spirit to clean my derma roller?
Answer: Step 2 is to clean your derma roller again, but this time in alcohol, surgical spirit (mix of ethanol and methanol) or you can use 60-80% of methanol or ethanol. ... Then use the same plastic container but filled with alcohol this time and soak your derma roller in it for about 20-30 minutes, to kill all bacteria.
