Rinse your lures down with fresh water after use and give your lures and lure trays a good clean with warm soapy water before storing for extended periods. This is important as it is often the residual salt in the lure tray or other rusty hooks that will set others off. In light of that you may also wish to remove or replace rusty hooks before storing. Vegitable oil or deoderised fish oil will also help to displace water and reduce corrosion to your trebles. Finally to hooks. Not only are better quality hooks stronger and sharper but often have better corrosion resistance. VMC and Owner hooks are 2 stand outs. VMC's can be purchased in bulk boxes at chain stores keeping the cost down but the owners can be 1 or 2 dollars a treble (i only have owners on some of my favourite lures that get used the most)
