Re: Saltwater reel
I carry a large spray bottle filled with a of 3:1 mixture of water & windshield washer fluid on every salt trip (regardless of tackle choice, fly or conventional).
After fishing we always remove the reels from the rods. Each guide & reel seat get a liberal spraying to remove any salt residue (seems so many worry about their reels and forget the rod).
The spools are removed so these and the inside frame of reel can be sprayed down. At home we strip all the fly line and run through clean water. Same for the rod & reel. Let all of this dry throughly.
All reels and reel seats are rubbed down with a old tee shirt soaked in CorrosionX. Use a old tooth brush with a bit of the CorrosionX to get in every crevice and around real seat. Bit of oil to the handle. EXTRA focus on your anti-reverse bearing, as NONE of these are Stainless Steel and are the first part to give you grief.
If you use extra effort on your gear suprisingly low end reels will work fine. During this time you can save for the the big $$ reels when you actually will fish for some of the real barn burners (tarpon & large pelagic fish).
