Cloth is reusable, and can be used to remove marks on wood caused by water, alcohol, and heat. It can also be used to polish metal and chrome.
Promising review: “I must admit I ordered this as a last hope. I had a mark on my bedside table that I tried various things to remove, but was totally unsuccessful. I tried this today, and there is NO sign of the mark. It is like brand-new again. I was thrilled with the result and highly recommend it to anyone, but would suggest you try it first to save yourself grief! It is inexpensive in the first place, but to know I can reuse it if necessary on another mark, (hopefully that doesn’t occur, but life happens), makes it an even better value.” —Kritik
