How often do you clean / wash your discs?
As title states. I just got back from a muddy round where several discs found some poison ivy. I usually give them a scrub in the shower with me and some Technu (probably doing too much) or Dawn in this situation. Sometimes I realize a handful of discs have some light dirt on them and I'll toss my whole bag in the tub to let them soak.
I've also played with some guys who don't ever clean them more than a quick wipe on the course and back in the bag.
Have you noticed anything different with the flight or your grip with a freshly cleaned disc vs. one that's never seen water and soap?
