After using Weber’s three-sided T-Brush for a grilling season, I have to wonder why I ever bothered with square grill brushes — in my experience the T-Brush cleans the grill faster and leaves it cleaner. It’s a little dirty after a year of use, but the bristles have retained their shape pretty well.
The three-sided description comes not from the shape but from the fact that it’s designed to clean the top and sides of the grill at once — sorry, you’ll have to flip the grate over to get the bottom, if that’s the kind of guy you are. The long-wearing brass bristles won’t damage your grill, not even porcelain-covered grates, and the triangle-shaped brush head lets you get right into the corners of the grill.
Weber sells their T-brush in 12″ and 21″ lengths. If you like to clean the grill after cooking a bunch of 75/25 burgers, you’ll probably want the 21″ long version. You’ll pay around $10 for either length brush.
