Help With Cleaning Headliner

[MacBB55]

So I have a 2004 525i, I have wanted this car for a long time and I finally got one, the best part is it came in excellent condition with only 118k miles on it, since I have gotten it I have put about 2k miles on it, it runs great. Here is my question, I have black interior with dark wood grain and a white headliner/roof whatever u want to call it, I have noticed lately that since that is the whitest part of the car its the part that shows dirt the most, I am wondering if anyone knows anything I can use, both solution as well as rag, or toothbrush/any other kind of detailing tool?

I would try woolite on a microfiber cloth. Of course in small area first.

I use Meguiars APC (gallon of concentrate), diluted to 10:1 and a microfiber towel.

So just an update, I figured out what works best for me to clean the headliner was a toothbrush with nothing on it and then vaccum, for the one spot I had that needed a lil scrubbing, I took a brand new microfiber cloth and put a tiny tiny bit of cleaner on it, scrubbed the spot for a second then finished it with the dry, new tooth brush, you could never tell this car is as old as it is due to the excellent condition I can only hope to keep it this way.
