How to Renew a Weber Grill

Pull out every removable part of the Weber grille internals, including the cooking griddles and the ceramic flame covers if restoring a propane model. Use a paint scraper or brush scraper to chip off and remove all of the burnt residue on the inside BBQ walls. Place a bucket underneath the drain hole to catch all the residue and waste. Use oven cleaner if necessary to break up grease deposits. Wash the entire surface down with soap and water and use a steel wire brush to remove smaller bits from the inside surface. Do the same kind of work on the griddles and ceramic covers that were removed.

Let the washed BBQ body dry and go over the entire surface again with a steel wool or wire brush. Smooth out the entire surface with sandpaper so that it forms a grit and tractable surface (skip this step if the outside BBQ paint is still in good condition). Remove any rust that is visible, inside and out. Wash the BBQ down again with soap and water and let dry a second time.

Mask the handles and control areas with masking tape so they won't get painted. Use a spray paint (preferably black) that can handle temperatures up to 1000 degrees Fahrenheit. Apply the paint back and forth in thin layers. Do not paint the inside of the BBQ. Paint a good layer on the top and bottom components of the BBQ body. Let the paint dry between each coat and apply again. Allow the finished paint work to dry completely for a day. Remove all of the masking tape afterwards.

Start up the BBQ to heat it up. If the started doesn't work properly, clean it out with pickle juice and a scrubber. Replace the pilot flame nozzle with a new one purchased from your local hardware or garden store. Heat up the BBQ to at least 500 Fahrenheit and hold it there for ten minutes to cure the paint.

Scrub the griddles and upper deck wire tray for bread with the wire brush. Replace them with new parts if the rust won't come off from a thorough scrubbing. Check the propane hosing underneath the BBQ for any kinks or cracks in the hosing. Replace the tank spigot and hosing if necessary with a new set. Install a new drip tray underneath the BBQ body. Recover until needed for cooking.
