Like beautiful ambition above said, scrub it with a new tooth brush(your used one could have a lot of bacteria) and then take another good look at the roller and make sure the needles are free of debris. Put it in alcohol for a while and rinse it in water for a few seconds right before use.

Alcohol won't be enough, I would use a toothbrush and some soap to clean off the needles or a denture for people who don't have teeth ... tablet. Hibiclens is good to use even on the skin before you needle, you can find it in the first aid. Finally Iodine is a great bacteria killer, it does stain a little bit because it's so dark but you can also use that on your skin and or the needles to disinfect. You can pour boiling hot water over the needles as well, just don't put it in the pan.

I would try a few of these things, beautifulambition.

If in doubt about rust, throw it away.

Thank you for your reply, beautifulambition.

It's too old, buy another dermaroller or dermastamp.
