Your SR has a tung-oil finished neck, whereas your Fenders either have a gloss finish, or a matte satin finish. The latter two, you can just wipe with a cloth, and take all sweat, oil, and other crap off. Tung-oil finishes require something like lemon oil, to get sticky gunk off your neck or body (your SR's body is oiled, too). Tung-oil finishes are simply a cheap and/or "natural" alternative to hard gloss or satin finishes. It's just finishing oil that penetrates into the wood, to create a hard seal INSIDE the wood, so you feel the natural texture of the wood. A lot of people like oil finishes because not only for the natural feel, but since they are a lot lighter/thinner than gloss or satin, they believe this lets a lot more of the natural tone through. But, you do have to use more than just a towel to get gunk off here, since the tung oil leaves the surface of all the wood's pores exposed. Also, an oiled finish can decay, by drying out over time. That's why you need something like lemon oil. It's acidic enough to get into those little pores, and take junk off a natural tung finish, but safe enough that's it's an oil, so you're feeding the wood at the same time. Remember, don't use a lot of oil-too much will leave a lot of build-up, and a little goes a LONG way. Finally, DO NOT use regular guitar polish or car polish on a tung oiled neck and body. This will ruin the wood. Gloss and satin finishes totally cover up the wood surface, and are really hard and thick, so a regular heavy-duty polish is safe for these finishes, and will not harm the wood-kind of like hard finishes on furniture. Oh, and besides lemon oil for finish, never use any oil cleaner (like Murphy's Oil Soap), that has petroleum-based ingredients-these are too harsh on tung oiled INSTRUMENT surfaces. I hope this helps!
