In general "exotic" leather (such as elephant, lizard) are cared for by brushing off loose dirt or dust, then cleaning with a leather conditioner. Afterwards, apply a thin coating of matching wax polish then buff with a soft cloth.
After doing a little research for you... If you really want them to last, keep a beautiful shine be softer to the touch. Meltonian #170 delicate boot cream (same as caring for lizard skin cowboy boots) is the way to go on reptile skins.
Hope this helps.
