The Virtual Weber Bullet - Cleanup, Maintenance, and Storage Cleanup, Maintenance, and Storage Proper cleaning, maintenance, and storage of your Weber Bullet will keep your unit operating properly and looking good for years to come. Just follow the tips below to get the most out of your investment in Weber quality. It's best to clean your Weber Bullet as soon as you can after cooking. Wash the cooking grates using hot, soapy water, then dry thoroughly. Alternatively, use a brass bristle brush or crumpled aluminum foil to remove large debris, then burn-off the residue over hot coals or in your gas grill before your next cooking session.
Some folks wash their cooking grates in the dishwasher.
I've tried it, but it didn't work so well for me. The grease was removed, but a lot of debris and smoke residue was left on the grates and I ended up washing them by hand anyway. However, you might give it a try to see if it works for you. Carefully remove the water pan. If the fat has solidified on the surface of the water, skim it off and place it in the trash.
