Old English furniture polish will cover a multitude of sins as long as you aren’t talking about fine furniture. Try wiping some on in an out of the way spot to see if it suits your needs.

I agree. Any dark stain that is approximately the same tone as the finish will darken up those worn, light spots and make them much less noticeable. What I wouldn't try to do is sand and re-stain: the damage is not that bad, and doing something more ambitious will open up a whole new set of issues.

I've found that leather dye in an appropriate color works very well for wood touch up. Use a cloth or semi dry brush it on and finish with a cloth...don't spill it! (:

Oh good, I love easy solutions and lucky for me I already have a bottle of Old English!

Old English Scratch Cover is pretty good stuff. Works great if the wood you're polishing is reasonably close to one of the two shades (light and dark) they offer. Been using it for close to 5 decades now.

More recently I discovered Howard Restore-A-Finish, which comes in NINE wood shades. I like it even better.

The RAF can is twice the size of the Old English bottle, but less than double the price at the hardware store up the road from here. So I guess it's a better deal. However, one bottle of Old English usually lasts me 10-15 years, so I'm not sure that matters much.
