like the title says, my 66 toro has mildew on some of the vinyl (cloth is ok) and it just stinks inside (mainly from mildew). I know it had mice in it, so I'm probably missing a couple mouse nests which cause odor, but how can I get rid of the smell and mildew on the vinyl?

 

Sounds like a leaking heater core.

 

Water and bleach work to get rid of mildew, just be careful of the cloth carpet etc.

I had a funky smell too in my car, I used baking soda, dryer sheets, febreeze etc but it still had the smell. Finally after the dash was out I discovered it was the old dash insulation that was retaining the smell. There would have been nothing that could have gotten rid of it except replacement. Good luck.

 

I scrubbed the entire interior of mine with 409 when I first got it. There was mildew on all of the interior panels.

 

Your local RV dealership has stuff special for getting rid of the smell.

 

Is there a cause for the mildew?

 

the mildew was caused by sitting in a damp garage for 20 years.
