sunsanvil I really don't believe you've ruined anything, but try using dry wood, perhaps larger pieces, if available & only a personal preference here, but avoid mesquite....it really puts a heavy flavor quite & is a pretty oily wood (seems you know this already )
This is small oak chunks,
used for a quick cook, seen here ~~~>
http://weberkettleclub.com/forums/food-pr0n/pork-tenderloins/You can pretty much add wood for flavor to any cook, but always keep in mind the wood itself is also added fuel, meaning added heat.....that mesquite is one of the hottest............
If you'd like to use chips, just load a large handful in a double or triple thick aluminium foil packet
( make one up by hand ) wrap semi-tight (so the chips don't punch thru ) poke 4~5 small holes in the packet, get rolling on your cookup & flop the packet on the coals.......it will huff & puff for 15~30 minutes & pretty much let you know by looking when it spent.....more smoke? more packets........
Or, you can just be silly like me & throw loose chips on the coals, they burn faster, but you'll still get the flavoring.....
As far as cleaning what you have layered onto the surfaces, not sure what would work good.....you could do the whole take apart scrub down, into the garbage bag with oven cleaner, hose off, dry off, re-assemble, run a load of charcoal to make sure cleaners are gone.......
.....OR, like I do, just keep cooking.......the wife went out & bought her own OTG brand new after this: "I smelled all yours & they ALL smelled like smoke..."
