I did this last week. I used Johnson & Johnson Baby Oil Gel.
Then I put socks on and slept through the night.
It was hard to get the stuff off of my feet, but they looked as if they had been treated to a paraffin dip! It was really nice, and no need to do it every night or anything! I changed the polish on my toes and it looked like a brand new salon pedicure even though it had been over a month since my last one.
