The Primo Grate Cleaning Bar is for cleaning cooking grates. You work it along the bars of the grate, taking off the carbon and cooked-on residue that builds up over a run of cooks.
Timing does most of the work. Residue that is still warm comes away with very little effort, while the same residue cold and set takes real scrubbing, so the habit worth forming is to run the bar over the grate at the end of a cook while the grill is still hot rather than at the start of the next one. Clean bars also stop old fat carrying its flavour into whatever you cook next.
Keep it with the Primo Grate Lifter so you can bring the grate up to a comfortable working height, or the Primo Grate and Deflector Lifting Tool if you are handling deflectors as well. Browse grilling accessories for the rest, or the full Primo range for everything Primo.
