If a brush was better, wouldn't MB have designed one for use in their cars?

I didn't have the reamer handy or I would have tried the reamer then blow it out and see if the brush can scrape off more dust. Note, there wasn't a lot to begin with.
They also designed the 722.6 which was said to be lifetime fill. I tend not to take the word of MB as the final word. Sure, they have a say but I don't take them as the be all and end all.
