Spanish english translation please help!?

I am in mexico and am wanting to get a tattoo from an artist here who doesnt speak great english.

I want to ask him-

1. How does he sanitize his equipment?

2. What kind of needles does he use?

3. I have a tattoo on my arm and I would like his opinion of how to finish it, because I am not happy with the original idea.

4. I have a tattoo on my shoulder I would like covered/disguised, and need to know if this is possible.



Can someone please tell me how to ask these questions in spanish?

(btw, i am a tattoo artist, my spanish just sucks)Spanish english translation please help!?
