My standard cleanup is:
1. remove and discard the pad under pass side footwell
2. pour water in, wet-vac it out
3. repeat until water seems coolant-free
4. soak up remaining water with towels
5. use plastic containers (cool-whip or similar) to prop carpet up off floor
6. open both doors. remove dome lite fuse
7. aim box fan into pass door
8. let it blow over nite.
9. get new padding. I got a roll of that JCWhitney stuff with aluminum foil on 1 side. Used 2 layers.
You can probably rinse, dry the padding and re-use it. I choose not to. HTH
