For the usual cleanup, of dirt, spatter, insect spotting, I think Windex or maybe 409 work well. When we got our Burro
, I felt a bit more was demanded in certain areas involving various sorts of stickum. Used GooBegone and Bestine. Good ventilation required when using either or both. I like Turtlewax "Icewax" car polish but almost any spray furniture wax (Pledge) produces a barrier layer that makes it easier to clean the next time. I don't have spider cracks in the interior liner so no experience trying to hide them.
