マグノリアブラシ RAD-3 | 3インチ ラジエーターブラシ

The 3-inch width is perfect for getting between those tight radiator fins without any bending or struggling. I've used it on several old cast-iron units and it saved me hours compared to my old rag-and-screwdriver method. Definitely worth the money for the build quality alone.

Finally, a radiator brush that doesn't feel flimsy—the bristles are stiff enough to actually scrub the dust out from between the fins. I’ve been through three cheap ones this year, but this professional-grade head gets the job done in one pass.

The bristles feel stiff enough to tackle caked-on grime, and the handle has a good weight for extended scrubbing sessions. I wish the head were a bit narrower for tight corners, but it’s still a solid tool for larger radiator panels.
