Hi ksg

I also think no harm can be done to electrics or to the metal floor as the coolant is glycol based, being a little sticky and greasy. I thought taking the car to an auto cleaning shop to have the carpets washed but there are too much corners and small round surfaces for it to be effective. I liked your idea about using some absorving polymer and then vacuum it, but what I'm really worried about is if some kind of nasty smell persists after all this has been done.
Climate here is still hot and sunny which might help a lot.
