I have a Weber Propane model if that makes a difference

My Weber brand gas grill is coughing. It’s got two burners, and when you light it, the fire is supposed to spread over to both burners. However, that does not happen. I thought the small holes that inject the gas were blocked so I used a steel brush trying to open them but that did not help. Now I think the gas pipe is blocked, so I’m wondering how to remove the blockage. Any ideas?

What can I use? Tried vinyl cleaner, lysol etc.

I have a Weber grill. It is my second one; the first one caught fire and so I used a fire extinguisher on it. Since it was covered with a layer of white chemical powder, I got a new one. Today, it happened again, but the grill is pretty new. Can I just replace the grill and flavorizer bars, scrub the rest and start grilling again? Or will those chemicals make the food unsafe or taste bad no matter how I clean it?

first …go to a restaurant supply place and get a grill brick..its pumice and will form to the grate width. minimal pressure will make it look like new… and they are very very inexpensive.
