My wife (being the most-prepared person on earth

) actually keeps a fire extinguisher in each of our cars.
Yesterday, she set back and reclined the front seat to realx, and caught the extinguisher's trigger and the thing exploded inside the car

.
She spent the next 90 minutes wiping the fine green gains from the interior, but being at night, we didn't know if she got it all. Map pockets, ventilator flaps, etc. etc.
I have an appoinement with a detailer to let the pros handle this. Does anyone, especially Greg, know if these extinguisher grits are corrosive, or can do long-term damage to the interior?
No, no, no it's not the M5

but our 4 days old Highlander.
Thanks for your education.
