Soap and water didn’t quite do the trick? You may need to move on to something a little stronger. Continue to use your soft rag, but this time use vinegar as a chrome cleaner. Because vinegar (either plain white or apple cider) is slightly acidic, it works well for taking tarnish and gunk off of chrome. This can be used to clean chrome rims, chrome pans, chrome bumpers, or whatever else you’ve got. Just remember to use different parts of the rag as you go along so you’re always using a clean section. If you need a little extra umph, sprinkle a little baking soda on the vinegar-dampened rag.
