I have heard of a SL Rib being a spare rib with the tips taken off but not the skirt. A KC rib is the same as the SL but with the skirt taken off. But most people will still refer to it as a SL rib because more people know that terminology. Heck, even I do that.

All I do is put foil down on the bottom, the heat shield, and the drip trough on the right before I use mine. This speeds up the cleanup process. Beyond that, I vacuum it out after using it and clean the racks off. Then every 2-4 months, I scrape down the sides of any excess buildup. That's it.

And yes, you can spray down the racks with vegtable oil to help in the cleanup

I've heard of KC Style spares being the same as the St Louis style except with the fat scraped off of the back side or the ribs.
