Made from untreated cedar, these are long-lasting and much safer than bristle brushes. Images are burned in using a laser. Simply turn on your grille and once it is hot, scrape the grille. The heat will burn grooves in the cedar and if needed, you can cut the burned part off and have a fresh scraper. I’ve used one for about 7 years and have yet to re-cut mine. If you have a graphic, I will happily personalize one for you.
