Hi everybody, I'm housesitting for some friends with stainless appliances. They warned me not to open the fridge and oven doors at the same time because they were installed too close to each other. Well, you can probably guess: I forgot about this unusual restriction and opened the fridge to add something to the oven—bam! There's now a dark mark, about 1/4" wide, on their practically-new Samsung side-by-side (see photo). The mark's a different color from the fridge, so I can't tell if it's actually a scratch, or just some kind of coloration that was transferred from the oven door. I've tried Windex, baby oil, baking soda applied with a Q-tip... but it's still there. I'm just sick about this. Have any ideas how I may be able to fix it? I'm reasonably handy, so suggest away. Thanks!
