I still have to clean mine even though they're the day/night contacts you leave in, and have gone through any number of different solutions. Some of them were terrible and made the contacts cloudy or dry out faster (even the more expensive ones). I can't remember which ones right now.
My favorite to date is Clear Care, where you have to let it sit and bubble for 6 hours. It looks like this:

If you put them back in before then, it feels like you washed your eyes in hot sauce! It's hydrogen peroxide activated by some little disk. I need to buy a new bottle of plain saline or cleaner as a backup pretty soon.
