Nitromors is the best paint stripper around. If you are sure there is lead in the paint then use a facemask as well as gloves. The trick is not to generate too many fumes or dust so sanding and burning the paint off is not recommended. Nitormors do a tester kit too if you are unsure about the surface you are about to strip.
