How do you remove glue from a dashboard?

It depends on the type of glue.

Elmers white or wood glue: use warm water and a cloth rag.

Rubber cement: Peel it off if possible. Use toluene (type of paint thinner) for residue that doesn't peel off.

Krazy/super glue: Assuming a plastic dash, use your thumb to apply pressure to the dash and make it flex slightly. Repeat this process for a few minutes, the peel the glue off. Cold temperatures may help.

Hot melt glue: Peel off.

Rearview mirror glue: If it doesn't peel off easily, shine a blacklight on it for a few weeks, then peel off.

Epoxy: Submit a query to the epoxy manufacturer. There are so many different epoxy type glues available.
