I agree, smokers are designed to accumulate grease and soot. Did you ever look at a commercial smoker and noticed how often they clean them...almost never when in continuous or semi-continuous use. Same with the flavorizer bars on my Summit 670. No rust as long as I use it; which is increasing a problem now that I have the SF.You guys need to get some grease in those grills. Mine is a big black grease ball.
This looks terrible, it means your barbecue accessories need to be replaced, I am using the Weber series of products now, there is no major problem at the moment, the quality is still very good, I bought it here-https://grillpartsreplacement.com/search?q=Weber&options[prefix]=last&type=product , If you encounter some problems and need to replace your grill, you can see if there are any products you need here, I hope my answer can help you, good luck!
Listen to none of the advice about sourcing new parts as bow.Mine has had plenty of grease in it, but I do scrape it into the drip tray regularly. I don’t do burn off but do cook high temps sometimes. These pics were after it ran at 500 for about an hour and I vacuumed out.
They are stainless per mfg, yes, but there is a small amount of ferrous content for them to have rusted. Try taking a magnet to them? If it barely sticks, low iron. If it sticks tight, they are low grade SS.Yeah it mostly seems like surface rust at this point but was surprised to see some on the flavorizer bars since I thought they were stainless.
Yeah Carl has to go!Listen to none of the advice about sourcing new parts as bow.
As you (Hopefully) already know, your EX is still very much under factory warranty.
Do NOT buy anything for it, and IF you do, be careful if you are not buying OEM! If you are concerned, reach out to Weber.
