just your standard acetone and cotton balls - the thing about MVP is that the stamps are a little deeper, and on proton are still perfectly readable (in my admittedly limited experience) after wiping and the neutron is less so, i believe due to the transparent nature of proton making the "etching" of the stamp stand out more. i haven't dyed any Z or champ plastic so i'm unsure if that is a common theme across candy plastics.
