I learned this valuable trombone accessory while I was in the U.S. Army Band as a trombone player. Use Lemon Pledge on your trombone slide. Lemon pledge has a wax in it that makes your slide move very easily, so if you spray it on your slide it makes it move very freely. Not only that, but Lemon Pledge actually tastes much better than trombone oil, Super Slick or even Rapid Comfort. Also if you are in a real pinch you can wipe some of the residue off your slide and wax your furniture with it. What more could you want from a trombone accessory?
