So the other day my GF said her neighbor had a grill she was wanting to GIVE away because her landlord said she couldn't have it at her apartment anymore. I go and look at it and I'll be damned if it wasn't a weber. Pretty sure its a summit S420. The outside is pretty nasty but the inside isn't too bad. Every thing works, each igniter for each burner works perfect, I put a tank in it and it fired right up. Have no clue how long its been sitting, looks like it wasn't used a whole lot. I looked it up on Amazon and I couldn't believe this thing goes for $1800!! Anyways, I have no clue how to clean the outside up, any advice?
