John,

I didn't say, but after you clean the track and bolt rope very well with the power washer you will still need to apply liquid soap as a lubricant to get the trampoline out of the track. Apply liberally. Don't use other stuff, it's not any better and won't incidentally clean the track.

Try flexing the trampoline as best you can along its length, be patient, and work from one end to the other. EG don't just pull at one end, but work along the length of the track/boltrope.

Unless you can't get the trampoline out... when you do remove the tramp, be sure to take a bottlebrush and ream the track out thoroughly. I have found that the bottlebrush that came with our kitten nursing kit was just right diametre.
