I love this brush from Griot's. Not only is it good for cleaning lug holes, but it's also great for those hard-to-reach gaps or cracks. I have an old Mercedes (white) and there are a lot of side moldings on these 2000 320's. And when it's a white car, these areas are sometimes brushed over with fine detail or soft brushes. This dirt isn't visible to most, but it really annoys me. This brush gets into all those areas and doesn't scratch them because the tips are smeared. This brush is soft and hard enough to hit those crevice areas and really clean anything. It works great around trim, valve stem holes, around headlights, just about anywhere. Highly recommended!
