S8 Red Needle Cleaner removes any ink, vaseline and biological matter from your needles. It contains plant extracts which dissolve any material which may collect in your needle groupings. Adding Red Needle Cleaner to the water in your rinse cups will result in better needle performance and cleaner colours when you're switching between inks. S8 Red Needle Cleaner is compatible with tattoo needles as well as cartridges. It is alcohol-free and will not cause any irritation or inflammation and it is safe for all skin types. Just like all S8 Red products, S8 Red Needle Cleaner is never tested on animals and is vegan friendly.
