Placing a musalla on an impure carpet and performing Salaah

Q:

1. If I place a clean musalla on an impure carpet can I pray on that musalla?

2. Also, if I make wudhu and then stand with my wet feet on the musalla that is on the impure carpet will the musalla become impure since the water penetrates the musalla and goes to the carpet or will it be pure. Because I heard a masala that if you wrap a wet impure cloth inside another cloth the other cloth won't become impure.
