good ol’ school chalk sticks are absorbent much like the silica gel packs inside of packages you buy.
Place one in many hidden locations like door pockets, glove box, under each seat etc.
– heck, if you can save some of those silica gel packs, use those too.
Take measures to not introduce moisture yourself like drying out the mats and kicking off as much mud or snow as you can.
When the oportunity presents itself,
have some windows open a tad and run the heater on high to push air out of the cabin while drying some.
do not park the vehicle with the a/c-heater in the recirculating mode.
My 06 Escape hybrid had interior frost two seasons in a row till I did these things.
