It’s understandable to feel concerned about the potential hazards of using a wire brush on a grill, as bristles can sometimes break off and end up in food, posing a health risk. If you felt strongly about it, it could have been beneficial to approach the topic gently and diplomatically. For instance, you could have expressed your concerns by saying something like, “I’ve read some articles recently about how wire brushes can leave bristles behind on grills. Have you considered using a different type of brush or cleaning method?” This way, you bring up the matter without creating a confrontational atmosphere.

However, whether or not to say something can also depend on your relationship with the host and the context of the gathering. If it was a casual event and you didn’t have an established rapport, it might have been wise to keep your thoughts to yourself to maintain a friendly environment. If you felt the situation was serious enough, and you have a good relationship with the host, offering your advice in a kind manner could contribute positively to their grill maintenance practices in the future.
