I have wooden counters in my apartment. My landlord is cheap and never put any type of sealer or whatever to protect the counter surface. So the counters are just bare wood basically. Not sure on the type of wood.

So as you’d imagine over the years some substances have come to stain the wood. Wine, coffee, etc. have left some splotches and rings from the wood.

Does anyone know any clever ways to remove such stains from the wood? Obviously I don’t want to do anything too harsh that may discolor the wood or something.

Help!
