Orange Gatorade has the same active ingredient as your furniture polish, orange extract. If you're in a pinch, it can work as a makeshift polish.
Don't go rushing to pour an entire bottle of Orange Gatorade on your furniture, though—you probably won't like the result. Fill half a bottle of Gatorade with water so there's a 50/50 mix. Then just use a small amount of that on your furniture and wipe it down with a clean soft cloth.
I was a bit skeptical, so I tried this out to make sure it wouldn't leave any residue or stickiness. Instead of pouring the Gatorade directly on the furniture I put a swig on the cloth. I got the same shine as my furniture polish would have left and not only was it not sticky, but the surface wasn't even oily to touch like I've seen in the past.
