Biostrip is my favourite, alavilable from local sources if you Google it - plenty of recommendations on here.
Dosn't stink like Dettol, not toxic like Brake stripper and won't melt your plastic/bendy plastic/resin figures.
Its also quick, dab on an 10-20 minutes later, scrub (gently) with an old toothbrush under a tap and back to the original.
I like Vallejo Surface Primer (73.602 in Black)
