Unless it has been waxed before I wouldn't use Pledge. I don't particularly like waxed finishes, much prefer an oil finish. Any of the rubbed in oil finishes will be fine. When dry they won't attract dust. Just don't put too much on at once. On areas that are particularly dry looking you can give several applications a day or so apart.
We have cherry in our coach and I just give them a light wipe a couple of times a year. Teak oil, tung oil, etc will give a durable finish, but don't apply too much at once. There is a difference between Pure Teal Oil and 100% Teal Oil. 100% Teak Oil does not contain dryers and takes about 24 hours to dry. Pure Teal Oil usually contains dryers and will therefor dry much faster.
Hint: If you want to see what it will look like when done, give it a wipe with mineral oil. It dries fast but isn't very durable.
Did I mention, don't apply too much at once and don't leave it too long ) more than 10 minutes) before wiping off any excess.
