1. Don’t dunk your reel in lake water. Even clear lakes have sand and other particulate matter floating in the water.
2. Use an approved reel oil and grease and don’t use WD-40. It’s a beeswax-based lubricant that when heated will leave a very hard finish that’s brutal to remove.
3. Rinse your reels at the end of every day on the lake with tap or bottled water.
4. Less oil and grease is best. Jamming too much lubricant into a reel will just slow it down.
