After a recent ice storm, my car was left with one of the windows cracked open (apparently my husband had accidentally hit the window control and didn't know it was open). When it started to warm up enough to melt some of the ice off my car, the water went right onto my passenger seat & the passenger side carpet - then refroze in the next cold spell. It started to mold and mildew while still frozen, but I don't know if I can get it cleaned up without ripping the carpet out.

Is there a cleaner that anyone knows of that is good for getting mold &/or mildew out of vehicle carpetting?
