Micro-Mark Nゲージ トラッククリーナー・オン・ア・スティック用 交換クリーニングヘッド（2個入り）

These replacement heads fit perfectly on the cleaner stick and made short work of the gunk on my N scale rails. The rubberized silicon carbide material scrubs effectively without leaving any residue behind.

The silicon carbide surface on these heads really bites into the track grime—my N scale layout runs noticeably smoother after just one pass. They’re a perfect snug fit on the stick, easy to swap out when dirty.

These heads are doing a noticeably better job on the gunk buildup than the felt pads I was using before, and the 3/4-inch size gets right into the tight spots on my N scale layout. I've already run a train over the same track after cleaning and got a much smoother ride than I did before.
