Mast Archer Wireless Tattoo Machine Rotary Tattoo Gun Pen Style Supply Coreless Motor 2,000mAh Battery Power 4.2mm Stroke Black

Q: can you adjust the stroke?

This does NOT have adjustable stroke. Clearly the people answering don't know the difference between stroke length and needle depth lol. Mast does have a cordless machine with adjustable stroke, but the archer is not it.

Q: What can I use to clean it ?

This should be wrapped to protect it from bloods borne pathogens. Do not use in direct contact with anything that has touched the tattoo or gloves. It cannot be cleaned it has way too many moving people ya and pieces blood will always be present.
