Reward for performing salaah by applying itr, wearing a turban or after performing miswaak

Q:

1. Is there any hadith that states that the reward for praying salah applying itr (fragrance) is 70 times more than offering salah without applying itr?

2. The same reward I have heard for offering salah wearing an عمامة (turban) for men, is it stated in any hadith?

3. Is the above mentioned reward given for a person praying salah after doing Miswaak as well?
