What is the best way to clean the bbq's, including the lid and the bottom of the inside of the webers. can you use oven cleaner?

Question edited for clarity, so few words, so many mistakes :>D
Question moved from Kitchen Ranges to Weber Grilling category.

Just behind the knob and valve there is a tube called a venturi that mixes propane and air and shoots it down to the burner. Your Venturi has a spider nest in it and is causing a flame just behind the knob.

There is a special brush made to clean it out.

I clean the burner holes with either a very small drill bit or a gas welding tip cleaner. its amazing how fast they get restricted or plugged.

You can actually get some good cooking tips at the weber on-line site. That said, you really don't want to concentrate on efficiency but rather on the type of food you are cooking. I always used to stack the brickets in the beginning to get them lit and graying and then spread them for an even heat to enable cooking on all of the grill surface. If you need more concentrated heat from below then leave them stacked or in a bricket rack.

Hello,
Either the cleaner you used is partially clogging the burner holes or you inadvertently moved the air adjustment and are starving it from getting the air it needs to burn properly. Douglas

My Genesis after a year or so begin to blister the inside of the lid

Also if you BBQ with lost of sauces your flavor bars could be your issue Try celaning them

Check to see if the probe where it sparks to the burner inside the grill is clean and not shorted by grease or other gunk and the burner itself in this area is not too heavily rusted or corroded. If not, short of disassembling the whole grill and replacing the spark module, spend $2-3 and buy one of those pistol type grill lighters. The ignition systems on BBQ grills rarely seem to last long.

you may have to remove the burners and clean the inside of them. they could have insect webs inside preventing the flow of gas. hope this helps. also, try opening the tank really slowly.

CLR is good .

Get rid of the fake coals they will only collect grease and cause a fire.

you can only use oven cleaner on enameled hood not on the cast painted parts like the body and sides of the hood those you can scrape and vaccum or brush

The best thing to use to clean the grill grating is a brass brush these may be bought at most hardware stores and even wal mart.
