IF no joy then using same method start with soap then if available.

traffic film remover, then a mild bleach surface cleaner.

If no joy then a steam cleaner will deffo work, but be prepared to do all the headlining

I prep cars for resale and still cringe at doin headlining.

just use min effort

& chemicals, keep it dry as poss AND DO NOT RUB
