Old English works really well,if it's really dusty I would use a swifter duster 1st.Will probally use several duster refills.Hope this helps!!!
Ron look at old school hardware stores for a product called Soilex. It is incredible at cleaning paneling. Mix it with water..it will turn green...wash the paneling down (no rinse needed) and when the water is longer greenish, change the water for fresh and go again. It usually only takes one time over and it will be clean.
I moved into a home built in the 60s that had knotty pine in 3 spaces. When I initially cleaned it, I used Murphy Oil Soap but to maintain it, I use something like Orange Glo. I get one of those cheap sponge mops and cut that plastic flap off of it and use it to apply the cleaner. Much easier on the back. Works like a charm. HTH
Dish soap, water, and a micro fiber mop. You don't need much soap to clean it.

And the best of luck to you! it's a PITA but after it's thoroughly cleaned you can paint it if you like!
If it is sealed with a polyurethane the cleaners you use could create damage or dull the surface. You also need to dry it after you clean it so water doesn't create more damage such as buckling.
I love Liquid Gold.
@Dottie Unruh me too.
I take an old hand towel and safety pin it on/over a broom. Spray the towel with whatever dusting; cleaning mix you want to use. I do not use a Swiffer duster. My sister did that to make it easier than the towel. She then had to remove fuzzes from the Swiffer duster.
so watch out for rough wood. Towel worked fantastic
