Specifically, the foil. Just tried to hoist new jib into the Schaefer roller furler, but could not get more than 1/3 of the luff tape and sail to travel up the forestay. Using a winch did not help. Absent another problem (we'll see) I figure the foil could be dirty inside the channel where the luff tape runs, and since it is a pretty close fit, the dirt could prevent smooth movement. Does anyone have general advice on this problem, and specifically a good, easy way to clean out the foil channel? I'm imagining a hook fashioned from a coat hanger to run up and down using the halyard and a line, with a small piece of soapy cloth attached inside the channel.
It never hurts to clean the foil, but if you couldn't raise it even by using the winch, I'd suggest you look for another cause. A friend had the identical problem that you describe with a Hunter, and the cause was a broken masthead sheave.
The way I would clean the foil on a C25 would be to use mineral spirits or denatured alcohol on a rag. Stuff the rag into the slot and change the rag often as it becomes dirty. You can either lower the mast and do it that way, or use a bosun's chair. My preference would be to lower the mast. It isn't difficult with the help of 2-3 strong friends. If you lower the mast, you can inspect and/or replace the sheaves at the same time.

I assume, with a C-250, that you have a CDI furler with its built-in halyard, so being a C-25/Hood furler PO, I can't speak to the sheaves involved. But indeed on the C-25, they become a problem and need replacement.
I'll assume you had this furler with an older sail that you could bend onto the furler without this trouble. On that basis, two thoughts: (1) Try a dry lubricant like Sailkote, spraying liberally into the slot as far up as you can reach, and then on the full length of the luff. (2) Talk to the sail maker and tell them you have a CDI furler (?) and are having this problem. (It's not unlikely they've heard this story before.)
Also, watch for bunching up of the sail fabric around the luff cable where the sail enters the slot.

Not sure the product is still around, it was called "Fasttrac" (no "k:). I think it is a French product. It came with a glide and a soft cloth that you ran up and down the sail track. I still have a little and use it on the mainsail track. I would not use a petroleum lubricant as they will gunk up.
